Importance+of+a+Network



**__Importance of Networking __** **Information 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 be built. Computer networks 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. **__Important Factors __** Computer Networks are useful in for instance a bank or office as they need to be able to have a shared area where data collected by some of them will be able to be used by the other workers. Networks are also important in schools with lots of computer rooms as it means the children can log on to any computer and have their own protected folder. Also it means that they can put their computer work into the shared area so that the teacher can mark it without having a massive pile of papers or books.
 * 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
