What is Network?
A computer network is a collection of computers and peripherals that are inter-connected to each other with the distinct purpose of sharing information, services and system resources. The computers of the network can be linked together using a wide variety of different cabling types, and for a wide variety of different purposes. The basic reasons why computers are networked are:
• To share resources (files, printers, modems, fax machines, storage devices)
• To share application software (MS Office)
• To increase productivity (make it easier to share data amongst users)
Take for example a typical office scenario where a number of users in a small business require access to common information. As long as all user computers are connected via a network, they can share their files, exchange mail, schedule meetings, send faxes and print documents all from any point of the network. A well networked office has the following advantages:
1. The physical devices like printers, fax machines, CD-ROM, modem, Tape drives of a computer can be share within the network.
2. With the help of networking, sharing of data can be possible from one computer to another computer.

3. Any system of the network can be access from any side of the network. The network allows for the sharing of resources between many systems, regardless of their location. This means less time spent trying to get to the computer with the printer.
