Internet is a more faster information in whole world wide just click and click and search and search then you will find the information you want without going to the other country, all of them is here in the internet thats why superhighway because information in the whole world you want to know is there and easily to find out. Popular discourse would have us believe that the Information SuperHighway will just be a faster, more powerful version of the Internet. But there are key differences between these two entities, and in many ways they are diametrically opposed models.

With a computer, a cable modem or a modem and a phone line, and the right software, you can enter a vast universe of information and interaction on-line. This on-line universe, known as the Internet, is a huge worldwide network of computers and other networks. What a highway system is to transportation, the Internet is to data. Research tools, documents, files and mailing lists are all readily accessible there. Network services, such as electronic mail, file transfer (FTP), World Wide Web and Hyper Text Transfer Protocol (HTTP) and remote login (TELNET) are offered by any computer that has implemented the full set of TCP/IP protocols (the highway system’s driving formats and rules).
