                          Connecting to growth markets

We have refocused CNT's strategic direction and positioned the company to
address customers' needs by achieving leadership in more robust technology
markets. Our long-term goals are to provide effective business solutions in
these markets in an effort to achieve sustainable revenue growth and improved
returns to shareholders. To help CNT achieve these goals, we are addressing
dynamic markets:

Storage Area Networks (SANs) With vital corporate information dispersed over
many different servers and networks, SANs provide a high-performance
infrastructure to protect that information against loss and also make it easily
available to those who need it. By the year 2000, the SAN market is expected to
be nearly $1.2 billion according to Strategic Research Corp. (SRC), an industry
research firm.

Web-to-Host Providing rapid access to mainframe information is an escalating
requirement for corporations seeking Web-based connections to link corporate
data and applications with open systems. International Data Corporation (IDC),
an industry research firm, estimates this market to be more than $1 billion by
the year 2002.

We will grow by serving the increasing global need for Storage Area Networks
(SANs).

     Businesses worldwide, including many CNT customers, now face a critical
need to make data accessible to users at all times because downtime causes
significant productivity losses and measurable costs. Millions of dollars in
annual downtime losses are not uncommon today because computer networks were not
designed for mission-critical applications such as mainframe data centers. For
this reason, a new kind of infrastructure is needed: one that provides network
availability, data accessibility, and manageability. The SAN is a high-speed
network that establishes a direct connection between multiple storage devices
and servers, thereby externalizing storage from the server and allowing
information to be shared among multiple `host' servers without affecting the
performance of the primary network. The SAN market segment is a natural
evolution of the channel networking market, encompassing both open systems and
mainframe environments.

     Our new UltraNet product family with our enhanced FileSpeed software and
Channelink products are uniquely positioned to provide customers with
applications such as disk mirroring, data archiving and retrieval, backup and
restore, and data sharing

between different environments. The SAN is quickly becoming an industry standard
among server and storage vendors, and CNT has established itself as a
connectivity leader in this rapidly expanding market.

We will grow by serving the accelerating need for Web-to-Host connectivity.

     Web-to-host integration is helping businesses leverage their huge
investments in mainframe systems by providing access to data and applications on
these systems in cost-effective and highly flexible ways. Extending the
enterprise to employees, customers and vendors via the Web enables businesses to
become more competitive, provide new products and services, and reach new
markets.

     The CNT Application Re-engineering Environment (CARE) solution suite,
comprised of the Enterprise/View (formerly the Web Integrator),
Enterprise/Connect and Enterprise/Access products, is well positioned to play a
leading role in this evolving market. As corporations begin to re-engineer their
applications for the Web, an orderly progression of development takes place,
from establishing a communications infrastructure to extending and integrating
host-based business logic and data into new applications. With CARE, these
corporations can now come to one vendor, CNT, to provide the products and
service that meet their Web-to-host integration needs.

We will grow by increasing our share of the traditional channel networking
market.

     CNT has long been a market leader in channel connectivity which had total
industry sales of approximately $189 million in 1996, according to IDC, an
industry research firm. Since l985, the Channelink family of intelligent
networking products has extended channel networking to unlimited distances
between host computers, and to local area networks (LANs), wide area networks
(WANs), peripherals, and workstations. Today as users look for effective ways to
preserve their investments in mainframe systems and peripherals, Channelink
provides a powerful, industry-leading tool for data center consolidation, data
center load balancing, and remote, high-speed digital printing and imaging.
CNT's leadership of the channel networking market also provides a strong base
for the evolution to a SAN environment.

Implications of this Strategy

     During l998 the successful execution of this strategy should position CNT:

 .    to be a leading supplier in the rapidly-growing Storage Area Network (SAN)
     and Web-to-host markets;

 .    to be the dominant vendor in the traditional channel networking market;

 .    to generate more revenue from products and services outside of the
     traditional corporate data center with products for administering
     distributed open systems and storage;

 .    to derive more revenue and earnings from the sale of higher-margined
     software and professional services;

 .    to employ broader distribution channels, including OEM partnerships,
     strategic alliances and arrangements with outsourcers, service providers,
     value-added resellers (VARs), and systems integrators; and

 .    to achieve improved expense ratios, sustainable revenue growth and
     consistent profitability resulting in improved shareholder value.
                                                                                
                                                                               3

                          CONNECTING WITH OUR SHAREHOLDERS

In l997 we set the stage for a new, stronger CNT that's more favorably
positioned to compete in new growth markets. This strategic refocus was
essential to strengthen CNT's potential to grow and deliver better financial
results and improved shareholder returns.

     We enjoyed the first signs of CNT's accelerating business momentum in the
second half of 1997. Revenue grew 33 percent between the third quarter and the
record fourth quarter of 1997. The new UltraNet product family accounted for 14
percent of fourth quarter product revenues. Fourth quarter service revenues also
rose 27 percent from the third quarter. This growth had two sources: the
addition of the service business of the Internet Solutions Division of Apertus
Technologies Inc., which we acquired in October, and CNT's growing installed
base. Fourth quarter operating earnings per share rose 50 percent compared with
the third quarter. 

     In 1997 we had marginal revenue growth, reporting record revenues of $97.8
million, compared with $97.1 million in 1996. Excluding non-recurring charges,
1997 net income was approximately $619,000, or $.03 per share, compared with
$3.1 million, or $.13 per share a year ago. After the acquisition and
integration charges, the 1997 net loss totaled $2.3 million, or $.10 per share.

     Fourth-quarter and year-end 1997 results reflected approximately $4.9
million, or $.13 per share, in non-recurring charges associated with the Apertus
acquisition and subsequent business integration. 

     CNT began 1998 with $10.8 million in cash and marketable securities.

     Although our net results for 1997 were not satisfactory, we are very
encouraged by our improved business momentum and the important initiatives that
continue to support our growth. 

New Strategy. We refocused our strategic direction to: 

 .    concentrate on critical new opportunities in the rapidly growing markets of
     Storage Area Networks (SANs) and Web-to-host integration, which are
     substantially larger than our mature, traditional markets; and

 .    increase our share of the traditional channel networking and SNA gateway
     markets. 

New Products. New products accounted for more than 30 percent of our 1997
product revenue. Among our most important new releases are:

 .    the UltraNet product family, which supports SANs and enables high-speed
     sharing and movement of data among diverse servers and data storage
     systems. The UltraNet Storage Director was named a 1998 "Hot Product" by
     Data Communications magazine.

 .    the FileSpeed software product, which provides high-speed data transfer
     between open systems and enterprise environments.

 .    enhancements that expand Channelink's versatility in wide area networks
     (WANs) including ATM, compression and disk mirroring (IBM and EMC).

 .    the Enterprise/View product suite, which provides cost-effective and secure
     access to mainframe applications and data from Java-enabled Web browsers.

                          Computer Network Technology

 
Investments and Acquisitions. To help support our new strategic direction, we
made several investments: 

 .    the $11.4 million acquisition of the Internet Solutions Division from
     Apertus Technologies Inc., which we expect to increase our market share in
     the rapidly growing Web-to-host connectivity market. This acquisition,
     along with ongoing quality and process improvements, improves our operating
     efficiency and profitability and gives us a critical mass to be a more
     aggressive player. We subsequently sold this division's Vision product line
     for approximately $3.5 to $4 million. 

 .    the acquisition of data movement technology for FileSpeed solutions, an
     investment that is beginning to pay off in new business such as our OEM
     contract with IBM.

 .    the purchase of more than 1.4 million shares of common stock for $6.7
     million out of a planned 2 million share repurchase program. 

New Customers and Partners. In 1997 we added more than 100 new accounts. We
continued to expand our distribution channels by entering into OEM agreements
with Bay Networks for our SNA gateway and Web browser technologies; Exabyte
Corp. for our UltraNet technologies; IBM for UltraNet and FileSpeed
technologies; and Hitachi Data Systems (HDS) for FileSpeed technologies. In
addition, our acquisition of the Internet Solutions Division significantly
expanded our business relationships with partners such as Lotus,
Hewlett-Packard, Sun Microsystems, Bluestone Software, and NetDynamics.

Management. Our senior management team strengthened in 1997, including the
addition of Patrick W. Gross to the board of directors, Greg Barnum as vice
president of finance and chief financial officer, Mark Knittel as vice president
of marketing and business development, and Martin Hahn as vice president and
general manager of the Internet Solutions Division. 

Looking Forward. Our goals in 1998 are to successfully execute our strategic
plan, grow revenues and return the company to consistent profitability. 

        We are encouraged by the market's reception of our new UltraNet and CARE
solution product families. These new products, along with others planned for
l998, are designed to foster direct and OEM sales and boost 1998 revenue. We
will also benefit in 1998 from increased demand for our systems consulting
services that support complex networking and Internet solutions.

        With the completed integration of the Brixton and Internet Solutions
Division, we expect to generate incremental revenues, realize significant
savings and improve profitability as we increase our presence in the gateway and
Web-to-host market.

        We expect to complete installation of a new enterprise resource planning
system in 1998. This will give us a new information technology infrastructure to
handle growth into the next century.

        Throughout 1998 we are seeking every opportunity to trim operating costs
as we grow revenues. Cash utilization should improve with close management of
inventories.

        The elements for CNT's success are in place. Excellence in execution is
our focus. We are aggressively pursuing new opportunities in high-growth markets
with new products, new customers, OEM partners and strategic relationships. I
want to thank our outstanding employees, whose diligence and expertise embody
the revitalized CNT every day.

        I believe our fourth quarter 1997 results are an indication of the good
revenue growth and steady profit improvement we hope to achieve for our patient
investors throughout 1998.


Sincerely,

/s/ Thomas G. Hudson

Today's businesses depend on the network to provide high-speed, reliable and
secure access to mission-critical stored information, whether it is centralized
or remote, from a variety of systems. CNT's UltraNet product family -- the
UltraNet Storage Director, the UltraNet Storage Gateway, and the UltraNet
Storage Multiplexer -- reduces information technology managers' resource expense
for storage management by connecting to any transport protocol on any platform,
using any operating system in any network. By providing high levels of
connectivity, performance, and manageability, the UltraNet product family
enables Storage Area Networks (SANs).

     The SAN is a high-speed network that establishes a direct connection 
between storage devices and servers, thereby externalizing storage from the 
server and allowing information to be shared among multiple `host' servers 
without impacting system performance or the primary network.

     Storage Area Networks provide an infrastructure for a wide variety of
applications such as disk mirroring, backup and restore, archiving and
retrieval, and data sharing that solve widespread business problems such as data
warehousing and business resumption. CNT's UltraNet family supports these
applications by enabling external and centralized storage as well as remote
clustering.

     The UltraNet product family is complemented by the existing Channelink
product line, and the two product lines can be combined in the same network.
CNT's FileSpeed software solution also works with both product lines to enable
high-speed data movement between mainframes and open systems.

     By providing a SAN solution, CNT is leading the market in addressing vital
customer requirements for lower total cost of ownership for integrated networks,
more timely business recovery and cost-effective, shared access to information
across the entire enterprise.

"When we consolidated operations during the recent merger, CNT UltraNet products
allowed us to transfer customer data from Portland, Oregon, to St. Paul,
Minnesota, quickly and reliably with less disruption to customer service than
traditional tape courier methods employed in past consolidations. They also
allow data to be transferred to and from our headquarters and two remote
distribution centers that support more than 1,200 bank branches located in 17
Midwest and Western states."

To keep their competitive edge, businesses today understand the importance of
providing information to anyone who needs it -- customers, employees, business
partners -- regardless of location. These organizations understand the strategic
benefits of Web-to-host integration in helping them leverage their enormous
investments in existing mainframe systems.

     As businesses begin to re-engineer their applications for the Web, an 
orderly progression ensues. First, a communications infrastructure is 
established to provide access to mainframe applications. Second, existing 
applications are extended to current users or employees. Third, existing 
applications are extended to new employees and customers, and other external 
users. Finally, mainframe-based business logic and data are extended and 
integrated into new applications that enable more efficient and targeted uses 
of mission-critical information.

     The CNT Application Re-engineering Environment (CARE) solution offers a
comprehensive set of products that takes an organization through each level of
the Web-to-host integration process. Enterprise/Connect provides the
interoperability between Web browsers and mainframe applications and data
through a channel-attached enterprise gateway. The Enterprise/View (formerly the
Web Integrator) is a Java-based emulator that provides familiar "green screen"
access to mainframe applications without reprogramming. The Enterprise/View Pro
(also part of the Web Integrator) is a re-screening tool that creates an instant
graphical user interface (GUI) on a Web browser for mainframe applications. The
Enterprise/Access is a powerful development tool and production environment for
extending existing applications to new environments.

     The CARE solution is an industry first in supporting all the steps in the
evolution of a successful Web-to-host integration. With CARE, CNT helps its
customers compete better, lower costs and develop new markets while leveraging
their mainframe investments.

"When one of our customers undertook a multimillion dollar initiative to deliver
new products and services, we looked for a scalable Web-to-host integration
solution. We selected CNT's technology because it was reliable, it was available
on a number of different platforms, and could support thousands of users rather
than hundreds. CNT's Enterprise/Access won hands down because of the ease with
which it can be implemented, and because it is much simpler to manage and
maintain."

Customer satisfaction is the number one priority at CNT. This commitment affects
the way we conduct business, from the development of new products and
applications to customer service and quality assurance programs.

     CNT's comprehensive support program uses remote diagnostic tools to support
customer networks. This unique ability to dial into dedicated networks worldwide
and perform on-line troubleshooting enables service teams to provide customers
with seven-days-a-week, 24-hours-a-day technical support. As a result, CNT's
customers get their problems resolved faster -- often without one of our trained
specialists having to visit their sites -- thereby reducing downtime. Customers
also depend on CNT to diagnose problems that are often identified as other
vendors' hardware and communications issues.

     CNT service teams provide pre-sales support by analyzing customer
requirements, developing solutions, and offering project management guidance
during product implementation and installation. Secure records are maintained of
all changes made to each customer's network, so that the network can be restored
more quickly in the event of a failure.

     With ever more complex networks handling mission-critical functions, there
is increasing customer demand for even broader services, especially
pre-installation network planning and design consultation. CNT also provides
more than 20 standard instructional courses on our product lines, as well as
customized courses geared to customers' specific networking issues.

     From the customer's pre-purchase contact to post-installation
reconfigurations, CNT's value-added services are focused on helping customers
achieve maximum long-term productivity from their networking investments.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS


ACQUISITION

     On October 24, 1997, the Company acquired substantially all of the assets,
including in-process research and development, of the Internet Solutions
Division (ISD) of Apertus Technologies Inc., (Apertus) a provider of
Internet-to-mainframe connectivity products and Web-access-to-legacy
applications. The purchase price totaled $16.4 million, including a cash payment
of $11.4 million, and assumption of $5.0 million of liabilities and related
acquisition costs. The amount related to in-process research and development of
$2.7 million was charged to expense in 1997 as the underlying research and
development projects had not yet reached technological feasibility. Subsequent
to the acquisition, the Company recorded a charge of $2.2 million for costs
incurred to integrate existing businesses, including accruals for severance,
facility closure, relocation of employees and other productivity initiatives.
The Company believes that it will be able to provide its customers with new and
enhanced products by combining the best elements of its existing technology with
new technology acquired from ISD. The Company anticipates that the acquisition
will increase its engineering and sales capabilities and expand its customer
base in the market for enterprise connectivity between Internet and intranet
users and IBM hosts. The Company also believes that the productivity initiatives
it has undertaken by combining ISD with its existing businesses will create
synergy and increase economies of scale.

REVENUE

     The Company's revenue primarily includes the licensing, sale and support of
products for high-performance enterprise networking and connectivity, enterprise
access and enterprise information management and recovery that integrates
traditional legacy data processing systems with open systems to create
enterprise-wide networks.

     Revenue from product sales totaled $68.8 million in 1997, a reduction of
approximately 7 percent when compared to the $74.2 million of product revenue
recorded in 1996. The decrease in 1997 product sales is primarily attributable
to a reduction in revenue from the Company's OEM partners of $8.2 million when
compared to 1996. During 1997, the Company recognized revenue from OEM products
sales to IBM, Bay Networks, Sun Microsystems and others of $4.8 million,
compared to revenue from OEM products sales of $13 million for the same period
of 1996. The reduction in 1997 OEM revenue was due to IBM's cancellation of an
order for the Company's channel connectivity controller. The decrease in 1997
product revenue resulting from lower sales to the Company's OEM partners was
partially offset by sales of the Company's new ATM and SRDF products and initial
sales of the Company's new UltraNet Storage Director products. In addition, the
sale of products acquired from ISD accounted for $2.3 million of new revenue in
1997.

     Revenue from product sales totaled $74.2 million in 1996, an increase of
approximately 22 percent when compared to the $60.9 million of product revenue
recorded in 1995. The increase in 1996 product sales was primarily attributable
to OEM sales of the Company's channel connectivity controller to IBM and initial
sales of the Company's new integrated gateway product. During 1996, revenue
recognized from OEM product sales to IBM, Sun Microsystems and others increased
approximately $10.6 million when compared to 1995 OEM product sales.

     Revenue from service fees, which primarily reflects maintenance, network
reconfiguration and professional services from the Company's technical support
personnel, increased in 1997 and 1996 by 27 percent and 28 percent,
respectively. The year to year growth in service fees is primarily due to the
growing base of customers using the Company's enterprise-wide networking
products and service fees resulting from the acquisition of ISD which accounted
for $1.3 million of revenue in 1997.

     During 1997 and 1996, international revenue increased 8 percent and 7
percent over the prior year, respectively, primarily due to increases in service
and product sales to international distributors. The Company derived 28 percent,
26 percent and 30 percent of its revenue from international customers in 1997,
1996 and 1995, respectively. The percentage of revenue derived from
international customers for any given period is subject to fluctuation because
of the variable timing of sizable orders from customers both internationally and
in North America.

     No single customer accounted for more than 10 percent of the Company's
revenue in 1997. Sales to one customer and its multiple divisions accounted for
18 percent of the Company's total revenue in 1996.

     During 1997, the Company announced its new Storage Area Network (SAN)
strategy and related UltraNet family of products which provides for high-speed
connectivity between storage devices and servers from anywhere anytime. Initial
shipments of the Company's UltraNet Storage Director products accounted for $5.5
million of revenue in the last two quarters of 1997. In addition, the Company's
new UltraNet Storage Gateway and Multiplexer products are expected to be
generally available and provide incremental revenue in 1998. The Company
believes the UltraNet family of products positions the Company for growth in a
new market segment.

     Integration of the ISD business acquired from Apertus with the Company's
existing business in the Gateway and Web-to-host growth markets should increase
the Company's presence in these markets and allow the Company to provide
customers with a new and improved set of products and services based on the best
elements of the existing CNT and ISD technologies.

     In addition, the Company obtained a number of new OEM contracts in 1997 and
early 1998 including Bay

                          Computer Network Technology

 
Networks, Exabyte and IBM, which should provide additional revenue in future
periods. The OEM agreement with IBM should result in increased sales of the
Company's UltraNet and FileSpeed products.

     The Company believes these new products and relationships should result in
increased demand for its products in both domestic and international markets.
The Company believes that it can increase revenue by continuing to acquire and
develop new products and services and by continuing to identify new applications
and markets for its technology, including the sale of these products through
OEMs, VARS, and other outbound technology initiatives.

     The Company expects continued quarter-to-quarter fluctuations in revenue in
both domestic and international markets. The timing of sizable orders, because
of their relative impact on total quarterly sales, may contribute to such
fluctuations. The level of product sales reported by the Company in any given
period will continue to be affected by the receipt and fulfillment of sizable
new orders from OEMs and others.

SPECIAL ITEMS

     During 1997, the Company recorded pre-tax charges of $2.7 million for
in-process research and development associated with the acquisition of ISD and
$2.2 million for productivity initiatives subsequent to the acquisition to
integrate existing businesses.

     In 1996, the Company recorded a $2.7 million pre-tax charge for the
write-down of purchased technology due to changing market conditions and
evolving customer requirements for SNA, Internet and open systems gateway
products.

     During 1995, the Company recorded a $2.5 million pre-tax charge related to
its management reorganization, which was included in the consolidated statement
of operations as follows: sales and marketing: $.2 million; general and
administrative: $.8 million; engineering and development: $1.5 million,
including $1.1 million to record an obligation on the part of the Company to
repurchase its common stock. Engineering and development was increased in 1997
by $.1 million and was reduced in 1996 by $.8 million to reflect changes in the
amount accrued for this obligation (see note 7 to the consolidated financial
statements).

GROSS PROFIT

     Gross profit margin from product sales in 1997 was 67 percent, as compared
to 65 percent in 1996 and 71 percent in 1995. The increase in gross profit
margins from product sales in 1997 when compared to 1996 and the decrease in
gross profit margins from product sales in 1996 when compared to 1995 is
primarily due to the high level of 1996 lower margin OEM sales of the Company's
channel connectivity controller to IBM. The gross profit margins generated from
the sale of products acquired from ISD are consistent with the gross margins
from the sale of the Company's existing Web and Gateway products. Actual gross
profit margins on product sales in 1998 will depend on a number of factors,
including the mix of products, market acceptance of the Company's new products,
the relative amount of products sold through indirect distribution sources and
the level of continuing price competition.

     Gross profit margins from services in 1997, 1996 and 1995 were 34 percent,
25 percent and 18 percent, respectively. The improvement in gross margins from
services in each of the last three years is primarily attributable to economies
of scale resulting from the steadily increasing base of customers contracting
for services. In addition, gross profit margins from services generated by ISD
have historically been higher than the Company's service margins. The Company
believes that any improvements resulting from economies of scale in 1998 will be
offset by additional investments the Company expects to make in its service
business to support new product introductions, including the Company's new
UltraNet family of products.

OPERATING EXPENSES

     Excluding the impact of special items, sales and marketing expenses
increased in 1997 and 1996 by 5 percent and 37 percent, respectively, when
compared to the prior year. The increase in sales and marketing expense in 1997
when compared to 1996 is primarily due to marketing expenses associated with the
launch of the Company's new UltraNet family of products and investments the

                          Computer Network Technology

                                                                              17

Company has made in its marketing organization to identify new market
opportunities for the Company's products. The sales and marketing organization
acquired from ISD also contributed to the increase. The increase in sales and
marketing expense in 1996 when compared to 1995 is primarily due to the
expansion of the Company's sales organization and an increase in commission
expense due to the higher level of sales. Improving the productivity of the
Company's investments in sales and marketing and controlling sales and marketing
expense as a percentage of revenue represent key objectives for the Company.

     The Company has identified the Web-to-host and Storage Area Networking
markets as strategic growth markets and believes that its future success is
highly dependent on its ability to successfully compete and sell products in
these markets. The sales and marketing employees acquired from ISD have
extensive experience and knowledge in the gateway and Web-to-host markets. The
acquisition of ISD has provided the Company with an opportunity to have a
dedicated and experienced sales organization focused on the sale of products in
each of the Web-to-host and Storage Area Networking markets. The Company
believes this dedication of resource will improve its sales productivity, allow
it to compete more effectively in the Web-to-host and Storage Area Networking
markets and should result in increased revenue in future periods.

     Engineering and development expense primarily relates to costs associated
with development of new products and enhancements to existing products.
Excluding the impact of special items, engineering and development expenses
increased in 1997 and 1996 by 20 percent and 32 percent, respectively, when
compared to the prior year. The increase for both periods is primarily
attributable to costs associated with continued development of new products,
including the Company's new UltraNet Storage Director that generated $5.5
million of product revenue in 1997, and its new UltraNet Storage Gateway and
Multiplexer products that are expected to add new incremental revenues in 1998.
The engineering resource acquired from ISD also contributed to the 1997
increase. The Company anticipates that the integration of the ISD engineering
team into its existing engineering organization should improve productivity in
future periods.

     As a percentage of total revenue, engineering and development expense
excluding special items increased to 18 percent of total revenue in 1997,
compared to approximately 15 percent of total revenue in 1996 and 1995. The
increase in engineering and development as a percentage of total revenue in 1997
is primarily due to the expense associated with the development and launch of
the Company's UltraNet family of products. The Company anticipates investing
approximately 15 percent to 20 percent of total revenue on engineering and
development in 1998, which includes investments in current and future products.
The Company believes a sustained high level of investment in engineering and
development is essential to customer satisfaction and future revenue.

     General and administrative expenses decreased in 1997 by 4 percent when
compared to 1996. The decrease is attributable to incremental costs incurred in
1996 for employee severance, and costs associated with the management
reorganization that occurred at the end of 1995. General and administrative
expenses excluding special items increased in 1996 by 23 percent when compared
to 1995, primarily due to higher costs for director and executive compensation,
including costs to recruit and retain a Chief Executive Officer and employee
severance. As a percentage of total revenue, general and administrative expenses
excluding special items were approximately 5 percent of total revenue each year
during the 1995 to 1997 period.

     Interest income decreased by $.3 million or 16 percent in 1997 when
compared to 1996 due to lower balances of cash and marketable securities
resulting from the Company's common stock repurchase program and acquisition of
ISD. Interest income increased by $.2 million or 15 percent in 1996 when
compared to 1995 because cash flow from operations in 1995 and 1996 resulted in
higher available balances of cash and marketable securities for investment.

     In 1997, 1996 and 1995, the Company recorded a provision for income taxes
at an effective rate of 41 percent, 33 percent and 38 percent, respectively. The
fluctuations in

                          Computer Network Technology

 
the Company's effective income tax rate for 1997 and 1996 is primarily due to
changes in the amount of non-deductible foreign losses and the large
non-recurring charges recorded each year. At December 31, 1997, the Company has
recorded deferred tax assets of $6.1 million. Based on an assessment of the
Company's taxable earnings history and prospective future taxable income,
management has determined it to be more likely than not that its net deferred
tax assets will be realized in future periods. The Company may be required to
provide a valuation allowance for this asset in the future if it does not
generate sufficient taxable income as planned. The Internal Revenue Service has
concluded its examination of the Company's United States income tax returns for
the years 1993 through 1995. No additional provision for income taxes resulted
from the examination.


LIQUIDITY AND CAPITAL RESOURCES

     The Company has historically financed its operations through the private
and public sales of equity securities, bank borrowings under lines of credit,
capital equipment leases and cash generated by operations.

     Cash, cash equivalents and marketable securities at December 31, 1997
totaled $10.8 million, a decrease of $24.2 million during 1997. The decrease is
primarily attributable to the cash paid to acquire ISD of $11.4 million and
repurchases of the Company's common stock totaling $6.7 million. Additional uses
of cash included the purchase of property and equipment, field support spares
and technology assets of $10.9 million. The use of cash noted above was
partially offset by cash provided by operations of $1.8 million, proceeds from
the sale of the Vision product line of $2.0 million, proceeds from the exercise
of stock options and issuance of stock under the employee stock purchase plan of
$.7 million and other of $.3 million.

     The Company's computer systems and those of third parties with whom it does
business will be affected when the year changes to 2000, commonly known as the
"year 2000 problem." The Company is currently conducting an internal study to
determine the full scope and related costs of modifying the products it sells to
ensure proper processing of transactions into and beyond the year 2000. The
Company expects that it will begin to incur costs in 1998 to address the year
2000 issues identified during the internal study. Although the costs to modify
its products are not expected to be significant, failure to achieve timely
completion of required modifications or conversions or failure of third parties
with whom the Company has relationships to be year 2000 compliant could have a
material adverse impact on the operations and financial condition of the
Company. In addition, the Company has determined that certain of its internal
business systems are not year 2000 compliant. The Company anticipates that it
will spend up to $3 million in 1998 for new capital equipment and software to
acquire and implement a new business system that meets the processing
requirements of year 2000.

     In addition, other expenditures for capital equipment and field support
spares have been, and will likely continue to be, a significant capital
requirement. Also, the Company intends to continue to repurchase shares of its
common stock on the open market from time to time pursuant to the previously
authorized common stock repurchase program.

     The Company believes that its current balances of cash, cash equivalents
and marketable securities, when combined with anticipated cash flow from
operations, will be adequate to fund its operating plans and meet its currently
anticipated aggregate capital requirements, at least through 1998.

     The Company believes that inflation has not had a material impact on its
operations or liquidity to date.

FORWARD-LOOKING STATEMENTS

     Certain statements in this annual report (which are summarized below) and
in the Company's press releases and oral statements made by or with the approval
of the Company's executive officers constitute or will constitute
"forward-looking statements." All forward-looking statements involve risks and
uncertainties, and actual results may be materially different. The following
factors are among those that could cause the Company's actual results to differ
materially from those set forth in any such forward-looking statements:

 .    The expected benefits of the ISD acquisition, including the development of
     new products and services, improvements in engineering, production and
     sales capabilities and increased market presence, may be impacted by
     unforeseen technological barriers, unanticipated integration expenses
     (including higher than expected commitments of management, engineering,
     financing and marketing resources) and customer acceptance.

 .    Future OEM revenue is dependent on the successful completion of engineering
     activities and the level of customer demand.

 .    The introduction of new products and the receipt of new product revenue is
     dependent upon the timely completion of required engineering activities,
     obtaining any required licenses and the product offerings of competitors.

 .    The results of successfully implementing the Company's new market strategy
     could be impacted by its ability to timely respond to customer demands
     through the acquisition or development of new technologies and the actual
     level and timing of the growth of the identified markets.

 .    The expected benefits of maintaining two sales organizations to address
     each of the Web-to-host and Storage Area Networks markets may depend upon
     the successful introduction of new products as planned by the Company and
     the actions of existing and future competitors.

 .    The amounts spent on engineering and development in l998, and what
     percentage this will be of total l998 revenue, may be impacted by the need
     to enhance or modify products due to changing market requirements, the
     success of current product programs, the need to meet unanticipated product
     opportunities and the amount of total revenue received in l998.

 .    The cost of achieving Year 2000 compliance, including the level of l998
     expenditures so related, will depend upon the actual amount of engineering
     and expense required to modify the Company's products and to implement its
     new business system. Successful installation of the Company's new
     enterprise planning system in l998 will depend upon obtaining the
     appropriate level of resources and management commitment. 

 .    Whether the Company enjoys increased demand for its systems consulting
     services in l998 will depend upon the successful introduction and market
     acceptance of new service offerings.

 .    Whether the Company has sufficient cash resources to fund its operating
     plans and capital requirements through at least l998 may depend upon the
     Company's ability to generate revenue as presently expected, unexpected
     expenses and the need for additional funds to react to changes in the
     marketplace.

         Other factors that could cause the results of the Company to differ
materially than those contained in any such forward-looking statements include
general economic conditions, costs and availability of components and
fluctuations in exchange rates. In addition, the markets for the Company's
products are characterized by significant competition and the Company's results
may be adversely affected by the actions of existing and future competitors,
including the development of new technologies, the introduction of new products
and the reduction of prices by such competitors to gain or retain market share.
The Company assumes no obligation to publicly release the results of any
revision or updates to these forward-looking statements to reflect future events
or unanticipated occurrences.

NOTES TO CONSOLIDATED 

FINANCIAL STATEMENTS 

December 31, 1997, 1996 and 1995 

(in thousands, except per share data)


1/ SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


DESCRIPTION OF BUSINESS

     Computer Network Technology Corporation (CNT) is a leading worldwide
provider of high-performance networking solutions that allow mainframe systems
and open systems environments to share data and information.

PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
Computer Network Technology Corporation and its subsidiaries (together, the
Company). All significant intercompany balances and transactions are eliminated
in consolidation.

REVENUE RECOGNITION

     Revenue from product sales is generally recognized by the Company upon
shipment or signed customer acceptance depending on the terms of the contract or
purchase order. Revenue from software license agreements with original equipment
manufacturers (OEMs) for redistribution to the OEM's customers is recognized
when the OEM reports delivery of the software to their customer. Service fees
are recognized as revenue when earned, which is generally on a straight-line
basis over the contracted service period.

     Deferred revenue primarily consists of the unearned portion of service
agreements billed in advance and amounts billed to customers prior to
recognition by the Company of the applicable revenue.

CASH EQUIVALENTS

     The Company considers investments in highly liquid debt securities having
an initial maturity of three months or less to be cash equivalents.

MARKETABLE SECURITIES

     The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 115 "Accounting for Certain Investments in Debt and Equity
Securities" (SFAS No. 115). The Company's marketable securities are classified
as available-for-sale and are carried at fair value in accordance with SFAS No.
115. If significant, unrealized gains and losses on available-for-sale
securities are excluded from earnings and are reported as a separate component
of shareholders' equity.

INVENTORIES

     Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market.

PROPERTY AND EQUIPMENT

     Property and equipment owned by the Company is carried at cost and
depreciated using the straight-line method over three to eight years. Leasehold
improvements are amortized using the straight-line method over the terms of the
respective leases. Expenditures for repairs and maintenance are charged to
expense as incurred.

FIELD SUPPORT SPARES

     Field support spares are carried at cost and depreciated using the
straight-line method over three years.

                          Computer Network Technology

                                                                              25

 
26

GOODWILL AND OTHER INTANGIBLES

     Goodwill represents the excess of purchase price over the fair value of
net assets acquired and is amortized using the straight-line method over periods
ranging from seven to 20 years. Purchased technology and other identifiable
intangible assets are carried at cost and amortized using the units of
production or straight-line methods over periods ranging from three to seven
years.

     The Company assesses the potential impairment of its goodwill and other
intangible assets based on anticipated cash flows from operations. No impairment
charges were recorded in 1997. The Company recorded an impairment charge in 1996
of $2,720 because it determined that certain purchased technology assets were
impaired due to changing market conditions and evolving customer requirements
for SNA, Internet and open systems gateway products.

ALLOWANCE FOR RETURNS AND CREDIT LOSSES

     An allowance is made for potential returns and uncollectible accounts
based on current and historical experience. The allowance for returns and credit
losses at December 31, 1997 and 1996 was $2,979 and $899, respectively.

ENGINEERING AND DEVELOPMENT

     The Company accounts for engineering and development costs in accordance
with Statement of Financial Accounting Standards No. 86 "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed" (SFAS No.
86). The Company has expensed all engineering and development costs to date as
costs which meet the capitalization criteria outlined in SFAS No. 86 have not
been significant.

FOREIGN CURRENCY

     The financial statements of the Company's international subsidiaries have
been translated into U.S. dollars in accordance with the provisions of Statement
of Financial Accounting Standards No. 52 "Foreign Currency Translation" (SFAS
No. 52). Under SFAS No. 52, assets and liabilities are translated into U.S.
dollars at year-end exchange rates, while equity accounts are translated at
historical rates. Income and expenses are translated at the average exchange
rates during the year. The resulting translation adjustments are recorded as a
separate component of shareholders' equity.

     Foreign currency transaction gains and losses are included in determining
net income (loss). The Company recorded foreign currency transaction losses in
1997 and 1996 of $45 and $99, respectively. The Company recorded a foreign
currency transaction gain in 1995 of $77.

INCOME TAXES

     The Company has adopted the provisions of Statement of Financial
Accounting Standards No. 109 "Accounting for Income Taxes" (SFAS No. 109). Under
SFAS No. 109, deferred tax assets and liabilities are recognized for the
expected future tax consequences of temporary differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases.

STOCK COMPENSATION PLANS

     The Company accounts for its stock based compensation awards in accordance
with Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
Employees" (APB No. 25) and provides the footnote disclosures required by
Statement of Financial Accounting Standards No. 123 "Accounting for Stock Based
Compensation" (SFAS No. 123).

RECLASSIFICATIONS

     Certain prior year amounts have been reclassified to conform to the
current year presentation.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

2/ MARKETABLE SECURITIES


     The Company's investments in marketable securities are summarized as
follows:


December 31                                      1997        1996
- -------------------------------------------------------------------
Corporate debt securities                    $  5,034   $  22,810
U.S. government and agency securities           1,000       7,408
                                             ---------  -----------
                                             $  6,034   $  30,218
                                             =========  ===========

     The amount of gross unrealized gains and losses with respect to the
Company's investments in marketable securities at December 31, 1997 and 1996
were not significant. The Company realized no significant gains or losses from
the sale of marketable securities during the three year period ended December
31, 1997. Proceeds from the sale of marketable securities during 1997, 1996, and
1995 were $26,252, $23,042, and $3,519, respectively. At December 31, 1997,
investments in marketable securities included $2,984 with contractual maturities
of one year or less and $3,050 with contractual maturities of from one to three
years.


3/ ACQUISITION

     Effective October 24, 1997, the Company acquired substantially all of the
assets (including in-process research and development) and assumed certain
liabilities of the Internet Solutions Division (ISD) of Apertus Technologies
Inc., a provider of Internet-to-mainframe connectivity products and Web access
to legacy applications. The purchase price totaled $16,429, including a cash
payment of $11,412 and assumption of $5,017 of liabilities and related
acquisition costs. The acquisition was accounted for as a purchase and,
accordingly, the net assets acquired were recorded at their fair values at
October 24, 1997, the effective date of the acquisition. The purchase price was
allocated as follows:

Current assets                                  $ 10,488
Property and equipment                             1,000
Other assets                                         672
Identifiable intangibles and goodwill              1,519
In-process research and development                2,750
Current liabilities                               (5,017)
                                                ---------
Cash paid                                       $ 11,412
                                                =========

     The amount related to in-process research and development as determined by
a third party appraisal of $2,750 was charged to expense in 1997 as the
underlying research and development projects had not yet reached technological
feasibility.

     The Company's consolidated financial statements include the results of ISD
since October 24, 1997. The following table presents the consolidated results of
operations of the Company for 1997 and 1996 on an unaudited pro forma basis as
if the acquisition took place at the beginning of each year:

                                     Unaudited Pro Forma

- ---------------------------------------------------------
Total revenue                        $117,000   $127,000

4/ INTEGRATION ACTIVITIES


     Subsequent to the acquisition of ISD in 1997, the Company decided to
consolidate certain operations and recorded a charge of $2,184 for costs
incurred to integrate existing businesses, including accruals for severance,
facility closures, relocation of employees and other productivity initiatives.
At December 31, 1997, a significant portion of the accrued liability for
integration activities remained unpaid. The Company currently anticipates that
the remaining liability will be paid prior to the end of 1998.

     In December 1997, the Company sold the assets and technologies relating to
the Vision line of products acquired from ISD for $2 million in cash, plus
additional payments ranging from $1.5 to $2 million through March 2001,
depending upon the Vision product line achieving a defined future revenue
target. The sale did not result in recognition of any gain or loss by the
Company.

7/ SHAREHOLDERS' EQUITY


COMMON EQUITY PUT OPTION

     In connection with a severance agreement entered into with a former
officer and director in 1995, the Company agreed to repurchase up to 280 shares
of its common stock on the last trading day of calendar year 1997 for a price of
$8.50 per share. During 1996, the former officer and director sold 183 common
shares on the open market which were subject to the repurchase obligation. The
Company's remaining obligation was satisfied in early 1998 when 97 shares of its
common stock were repurchased from the former officer and director for $828.

     Engineering and development expense was increased in 1997 and 1995 by $146
and $1,120, respectively, to record the Company's initial obligation under this
agreement and decreases in the market price of its common stock. Engineering and
development expense was decreased in 1996 by $779 to reflect termination of the
Company's repurchase obligation with respect to the 183 common shares discussed
above and an increase in

                          Computer Network Technology

 
the market price of its common stock.


COMMON STOCK REPURCHASE

     On March 10, 1997 the Company's board of directors authorized the
repurchase of up to 2,000 shares of the Company's common stock. As of December
31, 1997, the Company had repurchased 1,405 shares of its common stock pursuant
to this authorization for $6,688.

STOCK OPTIONS

     The Company's 1992 Stock Award Plan (the Award Plan) provides for the
grant of stock options and performance units to officers, other employees,
consultants, and independent contractors as determined by the compensation
committee of the board of directors. The Award Plan also provides for automatic
stock option grants to nonemployee directors of 50 shares upon their initial
election or appointment to the board of directors, and 20 shares each year to
nonemployee directors who are elected, re-elected, or are serving an unexpired
term as a director at any annual meeting of shareholders. A maximum of 5,400
shares of common stock are issuable under the terms of the Award Plan.

     All stock options granted under the Award Plan have an exercise price
equal to fair market value on the date of grant, vest and become exerciseable
over individually defined periods, and expire ten years from the date of grant.
Performance units entitle participants to payments of cash, stock or a
combination thereof and are based upon the achievement of specified performance
targets as determined by the compensation committee. As of December 31, 1997, no
performance units have been granted under the terms of the Award Plan.

EMPLOYEE STOCK PURCHASE PLAN

     The 1992 Employee Stock Purchase Plan (the Purchase Plan) allows eligible
employees an opportunity to purchase an aggregate of 500 shares of the Company's
common stock at a price per share equal to 85 percent of the lesser of the fair
market value of the Company's common stock at the beginning or the end of each
six month purchase period. Under the terms of the Purchase Plan, no participant
may acquire more than five shares of the Company's common stock or more than
$2.5 in aggregate fair market value of common stock (as defined) during any six
month purchase period. Common shares sold to employees under the Purchase Plan
in 1997, 1996, and 1995 were 164, 57, and 83, respectively.

     The fair value of each purchase right granted in 1997, 1996, and 1995 was
$1.66, $2.06, and $1.81, respectively.

FAIR VALUE ASSUMPTIONS

     In determining the compensation cost of stock option grants and shares
sold to employees under the employee stock purchase plan, as specified by SFAS
No. 123, the fair value of each award has been estimated on the date of grant
using the Black-Scholes option pricing model. The weighted average assumptions
used in these calculations are summarized below:

                              1997       1996       1995
- ----------------------------------------------------------

Expected volatility           39.3%      39.3%      39.4%

STOCK COMPENSATION

     The Company has elected to continue to account for its plans in accordance
with APB No. 25. Accordingly, no compensation cost has been recognized in the
Company's financial statements for stock compensation awards. Had compensation
cost for the Company's stock-based compensation plans been recognized consistent
with the fair value method of SFAS No. 123, the Company's net income (loss) and
net income (loss) per basic and diluted share would have been reduced to the pro
forma amounts indicated below:

                              1997       1996      1995

   Diluted                 $  (.17)  $   (.03) $    .13

     The pro forma disclosures presented above do not reflect the full impact
of stock based compensation on the Company's reported results under the
recognition provisions of SFAS No. 123 because compensation expense is reflected
over the vesting period of the award and compensation expense for awards granted
prior to January 1, 1995 are not considered.


8/ NET INCOME (LOSS) PER SHARE

     During 1997, the Financial Accounting Standards Board released Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS No. 128)
which the Company adopted as of December 31, 1997. Under SFAS No. 128, basic net
income (loss) per share is computed based on the weighted average number of
common shares outstanding, while diluted net income (loss) per share is computed
based on the weighted average number of common shares outstanding plus potential
dilutive shares of common stock. Potential dilutive shares of common stock
include stock options which have been granted to employees and directors and
awards under the employee stock purchase plan. SFAS No. 128 also requires
restatement of net income (loss) per share amounts for all periods presented.

     The components of net income (loss) per basic and diluted share are as
follows:

                                    Weighted

shares were excluded from the computation of diluted net income (loss) per share
in 1997, 1996, and 1995, respectively, because their effect was anti-dilutive.

      During 1997 and 1995, the Company's valuation allowance increased by $216
and $526, respectively, due to the nonrecognition of the tax benefit associated
with the loss from foreign operations. During 1996, the Company's valuation
allowance was reduced by $633 due to a decrease in the Company's available
foreign net operating loss carryforwards.

      The Company has assessed its taxable earnings history and prospective
future taxable income. Based on this assessment, management has determined that
it is more likely than not that its net deferred tax assets will be realized in
future periods. The Company may be required to provide a valuation allowance for
this asset in the future if it does not generate sufficient taxable income as
planned.


10/ SUCCESS SHARING
    BONUS PLAN

      The Company's Success Sharing Bonus Plan (the Plan) provides a formula for
determination of cash bonus payments to eligible employees based on a defined
percentage of a participant's qualifying base compensation multiplied by the CNT
Performance Factor (CPF). The CPF is derived from a matrix formulated by the
board of directors with axes consisting of defined levels of revenue

                                                                              31

growth and pre-tax profit.

      The success sharing bonus expense for 1997, 1996, and 1995 was $43, $582,
and $325, respectively.


11/      401(K) AND DEFERRED 
         COMPENSATION PLANS

      The Company has a 401(k) salary savings plan which covers substantially
all of its employees. The Company matches 50 percent of a participant's annual
plan contributions up to an annual maximum per participant of $1 which vests
over a four year period.

      The Company has also established an executive deferred compensation plan
for selected key employees which allows participants to defer a substantial
portion of their compensation each year. The Company matches 20 percent of a
participant's annual plan contributions up to an annual maximum per participant
of $10. Matching contributions vest over a four year period from the later of
July 1, 1997 or the participant's date of hire. In addition, the Company
provides participants with an annual earnings credit based on the investment
indexes selected by the participant prior to the start of each plan year.

      The Company's expense under the 401(k) and deferred compensation plans for
1997 was $380. The Company incurred no expense under these plans prior to 1997.


12/      DISCLOSURES ABOUT
         FAIR VALUE OF FINANCIAL
         INSTRUMENTS


      The following methods and assumptions were used to estimate the fair
values of financial instruments:

Cash And Cash Equivalents And Marketable Securities

    The carrying amount approximates fair value because of the short maturity of
    those instruments.

Common Equity Put Option

    The carrying value of the common equity put option (see note 7) was equal to
    the difference between the aggregate exercise price of the option and the
    current market value for the underlying shares. The Company believes the
    carrying value of the common equity put option approximated its fair value.


13/      NONCASH FINANCING AND 
         INVESTING ACTIVITIES AND 
         SUPPLEMENTAL CASH FLOW
         INFORMATION

      Cash payments for interest expense in 1997, 1996, and 1995 were $57, $46,
and $60, respectively.

      Cash payments for income taxes, net of refunds received in 1997 and 1995
were $986 and $5,306, respectively. Tax refunds received, net of payments, in
1996 were $304.

      During 1997, the Company entered into a capital lease obligation for
equipment valued at $989.

INDEPENDENT
AUDITORS' REPORT  ..............................................................

 ................................................................................

      We have audited the accompanying consolidated balance sheets of Computer
Network Technology Corporation and subsidiaries as of December 31, 1997 and
1996, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the years in the three-year period ended
December 31, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Computer
Network Technology Corporation and subsidiaries as of December 31, 1997 and
1996, and the results of their operations and their cash flows for each of the
years in the three-year period ended December 31, 1997 in conformity with
generally accepted accounting principles.

REPORT OF
MANAGEMENT  ....................................................................

 ................................................................................

      The accompanying consolidated financial statements, including the notes
thereto, and other financial information presented in the Annual Report were
prepared by management, which is responsible for their integrity and
objectivity. The financial statements have been prepared in accordance with
generally accepted accounting principles and include amounts that are based upon
our best estimates and judgments.

      Computer Network Technology Corporation maintains an effective system of
internal accounting control. We believe this system provides reasonable
assurance that transactions are executed in accordance with management
authorization and are appropriately recorded in order to permit preparation of
financial statements in conformity with generally accepted accounting principles
and to adequately safeguard, verify, and maintain accountability of assets. The
concept of reasonable assurance is based on the recognition that the cost of a
system of internal control should not exceed the benefits derived.

      KPMG Peat Marwick LLP, independent certified public accountants, is
retained to audit the Company's financial statements. Their accompanying report
is based on audits conducted in accordance with generally accepted auditing
standards. The audits include a review of the internal accounting control
structure to gain a basic understanding of the accounting system in order to
design an effective and efficient audit approach and not for the purpose of
providing assurance on the system of internal control.

      The Audit Committee of the Board of Directors is composed of three outside
directors and is responsible for recommending the independent accounting firm to
be retained for the coming year, subject to shareholder approval. The Audit
Committee meets periodically and privately with the independent accountants, as
well as with management, to review accounting, auditing, internal accounting
controls, and financial reporting matters.

GLOSSARY


ATM (Asynchronous Transfer Mode) - A high-speed
communications technology that transfers data, voice
and video information carried in fixed-sized cells.

Channel - A channel is an interface through which
mainframe computers transmit and receive information.

Channel Extension - Connection of mainframes to other mainframes, storage
devices, or peripheral devices over local area or wide area networks.

DS-1, DS-3 (Digital Signal levels 1 and 3) - Telephony
terms describing the 1.544 megabits per second and 44.7 megabits per second
digital signals.

Data Compression - The process of condensing the data in order to save storage
space and shorten transfer time; the original data is decompressed when read
back into memory.

Data Migration - Transfer of large volumes of data from one storage device to
another.

Disaster Recovery - A set of rules and procedures that allow a computer site to
be put back in operation after a disaster has occurred. The concept of moving
backups off-site constitutes the minimum basic precaution for disaster recovery.
The remote copy is used to recover data when the local storage is inaccessible
after a disaster.

Disk Mirroring - A data redundancy technique in which data is recorded
identically on multiple separate disk drives at the same time. When the primary
disk is off-line, the alternate takes over, providing continuous access to data.

Fibre Channel - Gigabit-per-second data transfer interface technology that can
merge high-speed input/output and networking functionality in a single
connectivity technology.

Gateway - A device connecting two or more networks that may use different
protocols and media. Gateways translate between the different networks and can
connect locally or over wide area networks.

HTML (Hyper Text Markup Language) - The language used in the World Wide Web to
create Web pages with links to other documents and rich text enhancements (bold,
italic, etc.).

Java - A software programming language developed at Sun Microsystems to solve a
number of problems in modern programming practice. The Java language is used
extensively on the World Wide Web.

LAN (Local Area Network) - A data network that enables communications between
multiple users (PCs, printers, etc.) in a limited geographic area -- generally
less than a mile.

Multiplexer - A networking device that condenses multiple communication streams
into one stream.

Protocol - A set of rules for communicating between computers. The use of
standard protocols allows products from different vendors to communicate on a
common network.

SAN (Storage Area Network) - A high-speed network of storage devices that
permits data movement and management.

Scalable - A scalable network is a network that can grow and adapt as customer
needs increase and change. Scalable networks can easily manage increasing
numbers of work-stations, servers, user workloads and added functionality.

SCSI (Small Computer System Interface) - A dominant, international standard
interface used by UNIX servers and many desktop computers to connect to storage
devices; a physical connection between devices.

Shared Storage - A storage resource is shared between multiple hosts and/or
clients, but each system has access only to its volumes.

SRDF - Symmetrix Remote Data Facility (SRDF) is a high-performance,
host-independent business continuance solution that enables users to maintain a
duplicate copy of all or some of their data at a remote site.

WAN (Wide Area Network) - A network which enables communications between
multiple users (PCs, printers, etc.) across a large geographic area, generally
anything outside of your home or office building. WANs typically involve
connections with telephone companies or Internet service providers.

WEB Browser - A program that allows users to access documents on the Web. They
read HTML coded pages that reside on a server and interpret the coding into what
we see as Web pages. (Netscape(R) Navigator(TM) -- Microsoft(R) Internet
Explorer(TM)).
