What is internet?

A word that doesn’t exist since 1883 and was used as a word to describe interconnected motions. Nowadays, the phrase The Internet is used to describe the network of millions of interconnected computer networks forming part of a global system that uses the Internet Protocol suite networking model to communicate to billion devices in the world.

Internet origin

And what’s the origin of Internet? The origins of the Internet date back to over forty years ago as a research project on packet-switched networks. In 1969, during the Cold War, the U.S. Department of Defense concluded that their communications system was vulnerable because it was based on the telephone communication (Public Switched Telephone Network , PSTN), a technology called circuit switching, a connection between calling and called which provides unique and limited number links between major nodes or central. This kind of communication, threatened the risk of having an isolated segment of the country if there were ever a military attack on those communications.

Alternatively, the Department of Defense, through its agency of Advanced Research (ARPA), decidedly encouraged the study of computer networks through student grants and grants to private companies. This investigation led to an experimental network of four nodes, which began in December 1969, was called ARPAnet. The central idea of this network was to get the information to reach its destination if part of the network was destroyed.

Years later the Department of Defense decide to use TCP/IP Protocol for ARPAnet netwotk, which provides an independent system to exchange the data between computers and local network of different origin. The name underwent some more changes, such as: Federal Research Internet, TCP / IP Internet and finally Internet.

The difference between the Internet and World Wide Web.

Nope, it’s not the same. The Web is one of the ways that information is distributed, it started with very simple pages and now is further developed that we can even find dating websites!

The Web is only a portion of the Internet. The Internet is much more, is used for communications on instant messaging, FTP software, social network, etc.
