The internet had its origin in the DOD’s (Department of Defense USA) efforts to build a controller that can get entry in any network that is very broad, stubborn and sturdy. Few years back DOD officials were worried because there was no such device to which you can connect almost any other network or computer. The DOD officials wanted to create a fault tolerant Wide Area Network that could carry, command, and control information in the event of nuclear war. Thorough research was made and the result was the Internet Protocol (IP) and APRANET (Advance Research Projects Agency Network), though original aim of this research was military, it was soon used for other purposes. Up to 1990’s the internet was largely used by Academic, Government and Industrial researchers. But with the invention of new application the WWW (World Wide Web) millions of new-academic users were added to the Internet.
Actually, internet is a web which has a very large numbers of computers connected to each other. These computers are connected with one and another either through wire, satellite, microwaves or fiber cables. They are so programmed using many software browsers, such as Internet Explorer or Netscape Navigator, than one can communicate from one computer to another computer within minutes. No one ‘owns’ the internet service. No one even really runs it. And no one can turn it off or on.
Everyone is welcome in the arms of internet as long as one’s computer runs the communication protocol/Internet protocol (TCP/IP). This universal standard allows different types of computers to communicate to each other, regardless of their make, model or operating system. In order to communicate information to travel on internet, a computer breaks down the information/ massage into smaller chunks of data called ‘packets’ and send these packets through ‘Modem’, and through the telephone lines. These packets move separately from one line to another, one network to another, till...
