Today's LANs are becoming increasingly
congested and overburdened. In addition to an ever-growing population of
network users, several other factors have combined to test the limits of the
capabilities of traditional LANs:

- The multitasking environment present
in current desktop operating systems such as Windows, Unix/Linux and
Mac allows for simultaneous network transactions. This increased
capability has lead to an increased demand for network resources.
- The use of network intensive
applications such as the World Wide Web is increasing. Client/server
applications allow administrators to centralize information, thus
making it easier to maintain and protect information.
- Client/server applications free local
workstations from the burden of maintaining information and the cost
of providing enough hard disk space to store it. Given the cost
benefit of client/server applications, such applications are likely to
become even more widely used in the future.
