To have an Internet connection we need a speedy computer, modem, telephone line and the help of an ISP (Internet Service Provider). The ISP maintains all accounts of Internet users. When a user sends messages from his computer, the modem processes them and sends them to the ISP and finally the server of the ISP sends them to the destination. Nowadays this type of Internet connection is going to be obsolete because the new broadband Internet connection is providing the users with the advantages of Internet access without telephone wires. It is done with the help of an antenna and some other required devices. Moreover, the broadband Internet connection can provide the users with all types of modern communication facilities at the cheapest rate. Our T & T Board has already introduced VSAT in our country by which the users can have a connection without telephone line through wires. As a result, cellular telephone or mobile phone is being used in our country. Now cellular phone provides the advantages of Internet connection. However, through Internet we can access any information-zone of the world having only a click on the computer’s mouse.
