History of the Internet: The history of the origin of the Internet does not go far. In 1960 the defense service of the Pentagon of the USA used It for the first time. The computer experts of the defense service introduced a system of internal relation among four different computers. This system was called ARPANET. In 1984 National Science Foundation of the USA introduced another system like this for the common people. It was called Nesfonet. In the course of three years, it gained wide circulation. In the meantime there emerged other small and middle dimensioned networks. Consequently, there arose some problems in communicating information through computers. To get rid of those difficulties a central network was formed at the beginning of the 90s of the last century. In 1993 it was exposed for commercial use. Within a short period, millions of members were connected with the Internet. At present more than twenty thousand networks are connected with an international network. Its users are increasing rapidly in every nook and corner of the world.

It is called ‘off-line’ the Internet or E-mail, In this process, the users send all their messages through computers to their nearer server. Through the interconnected server, this central server sends all those information to necessary computers at one definite time of the day. Besides, the recipients can collect the incoming messages at a fixed time of a day through a local call.
So it is found that off-line is an available cheap medium of communication. Importance of the transmit and receive messages quickly through the Internet/E-mail process, the message can be sent very quickly in a few seconds. It is the cheapest medium of communication. To send a letter in America one is to spend twenty to thirty taka whereas through E-mail it will cost 0.50 to 2,50 taka only. Its low cost is a threat to the use of Fax.
