Internet began in 1969. It
was a four computer network called ARPA net. It was used by U.S Defense
department for communication. After two years ARPA net grew into two dozen
sites. In 1981 it had more than two hundred sites. In 1990, ARPA net was
disbanded and new network came to be known as internet which consisted of
thousands of sites.
Gradually the commercial
organization began to recognize the importance of internet and they changed
whole world to a Global Village.
In internet There are two
types of computers known as servers and clients. Computers which offer
information to be read are called servers. Computers that read the information
offered are called clients. TCP/IP is the communication protocol which is used
by internet for world wide web to function.
