Nowadays the word ‘Internet’ is a household word and has become a very popular and interesting thing throughout the world. The world is becoming smaller day by day with the blessings of science. Almost every man in the world is either familiar or connected with this common word. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. Internet is a computerized network of information. It functions smoothly, easily and rapidly. A man can dial a number from his computer and a link to the Internet will soon give him a connection in and outside the country according to his expectation. It is practically a network of all networks. Many people use, erroneously, the terms Internet and the World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous. The World Wide Web is a primary application program that billions of people use on the Internet, and it has changed their lives immeasurably. However, the Internet provides many network services, most prominently include mobile apps such as social media apps, the World Wide Web, electronic mail, multiplayer online games, Internet telephony, and file sharing and streaming media services. The people of all trades including business communities, economists, teachers, students, politicians, and other professionals are now seeking necessary help and information through the Internet. Businessmen can learn the business trend and price of can go through several books from the libraries without going there. They can seek information regarding admission to different foreign universities. But it is a matter of great regret that many People of Bangladesh don’t have still access to the Internet. It is sorry to say that it is still costly and not easily available in our country.
