The Importance of Computer Networks
why and how computer networks support successful work
and communication are two of the most important
strategic issues for the success of every enterprise.
While today nearly every organization uses a substantial
number of computers and communication tools ( telephones,
fax, personal handheld devices), they are often still
isolated. While managers today are able to use the newest
applications, many departments still do not communicate
and much needed information cannot be readily accessed.
To overcome these obstacles in an effective usage of
information technology, computer networks are necessary.
They are a new kind (one might call it paradigm) of
organization of computer systems produced by the need
to merge computers and communications. At the same time
they are the means to converge the two areas; the unnecessary
distinction between tools to process and store information
and tools to collect and transport information can disappear.
Computer networks can manage to put down the barriers
between information held on several (not only computer)
systems. Only with the help of computer networks can
a borderless communication and information environment
allow the user to access remote programs and remote
databases either of the same organization or from other
enterprises or public sources. Computer networks provide
communication possibilities faster than other facilities.
Because of these optimal information and communication
possibilities, computer networks may increase the organizational
learning rate, which many authors declare as the
only fundamental advantage in competition.
this major reason why any organization should not fail
to have a computer network, there are other reasons
- cost reduction by sharing hard-
and software resources
- high reliability by having multiple
sources of supply
- cost reduction by downsizing
to microcomputer-based networks instead of using mainframes
- greater flexibility because of
possibility to connect devices from various vendors
Because of the
importance of this technology, decisions of purchase,
structure, and operation of computer networks cannot
be left to technical staff. Management as well has a
critical need for understanding the technology of computer
