Network

Before defining the term "Internet" it is better to tell you something on network.
A network is a group of computers connected tone another. When connected, computers from network can communicate with one another. That is, you can transfer files and text messages from one computer to another one.

One of the greatest advantages of a network is that you can share resources. Ie, Say you have five computers in your office in different sections. If all the five sections require frequent printouts, then you need five printers. If these computers are connected, then you need only one printer. Any of these five computers can issue the print command and take the printout.

Like printer you can also share hard disk within a network. There are lot of advantages by doing this. You can maintain an efficient central file system instead of copying files to a diskette and transferring to another computer.

Basically there are two types of networks, LAN and WAN. LAN (Local Area Network) is a group of computers connected to one another in an office or in the same building.

When one LAN in a building is connected to another LAN in a different location, we call it WAN.
