THE INTERNET AND WORLD WIDE WEB
Internet: is a collection of computer networks that operate to a common standard and enable
information
to be exchange between computers anywhere in the world.

HOW THE INTERNET WORKS
It works by passing data using the transmission transfer protocol or the internet protocol (TTP/IP) from
one computer to another. Such coordination is possible because every computer connected to the
internet uses the same rules and procedures (known as protocol) .To control the way data is formatted
and transmitted between computers. The protocols used by the internet are called Transmission Control
Protocol/Internet Protocols. All computers connected to the internet are maintained by large
organization and corporation as well as by Internet Service Provider (ISP). The ISPs sell internet
subscription to the public. A user subscribes to service providers which gives the user an identity user
name and a password and a phone number.

communicate and share information.
When few computers are connected in small places such as building or school, it is called a LOCAL
AREA NETWORK (LAN). If two or more LANS are connected together to cover a large area they are
called WIDE AREA NETWORK (WAN). The largest WAN in the world is the INTERNET.
