Well Rajesh,
Here is the full information about Internet.
The Internet is revolutionizing and enhancing the way we as humans communicate, both locally and around the globe. Simply put, the Internet is a network of linked computers allowing participants to share information on those computers. You should want to be a part of it because the Internet literally puts a world of information and a potential worldwide audience at your fingertips.
Internet History: The Internet's roots can be traced to the 1950s with the launch of Sputnik, the ensuing space race, the Cold War and the development of ARPAnet (Department of Defense Advanced Research Projects Agency), but it really took off in the 1980s when the National Science Foundation used ARPAnet to link its five regional supercomputer centers. From there evolved a high-speed backbone of Internet access for many other types of networks, universities, institutions, bulletin board systems and commercial online services. The end of the decade saw the emergence of the World Wide Web, which heralded a platform-independent means of communication enhanced with a pleasant and relatively easy-to-use graphical interface. Here is a link to an excellent Internet timeline at PBS Online.
Internet Activity: The information superhighway is literally buzzing with activity as Internet pipelines pump out all manner of files, movies, sounds, programs, video, e-mail, live chat, you name it. Yet amid all this activity there are always two key players in every transaction: a server and a client.
* Servers are computers with a 24-hour Internet connection that provide access to their files and programs. These can be but are not limited to educational institutions, commercial companies, organizations, government or military organizations, Internet access providers and various other computer networks of all sizes.
* Clients are software programs (and the people on remote computers using the software!) used to access files on a server (typically, a Web browsing program such as Netscape Navigator or an e-mail program such as Eudora).
Servers are typically located and organized by IP address and domain.
* An IP address (IP stands for Internet Protocol) is a specific set of numbers referring to a server's exact location on a network. Most domains have their own IP address, for instance, 192.41.20.33 is the IP address of my server at webcurrent.com. You can type those numbers in to get there, but the domain is easier to remember. An IP address also leaves your fingerprints wherever you "surf" on the net. Each modem connection typically is designated a specific IP address at Internet providers (this number typically changes dynamically as users log in), so you never really surf the net anonymously. You can be traced to a point.
* A domain is part of the server's official name on the network, an alias for the less descriptive IP numbers. Domains are organized by type of organization (a three-letter suffix) and by country (a two-letter suffix which defaults to the U.S. if no suffix is specified). You can tell a lot about a server by looking at its domain name.
o Here are some typical organizational suffixes: com=commercial, edu=educational, gov=government, int=international, mil=military, net=network, org=organization.
o Here are some country codes: au=Australia, at=Austria, be=Belgium, br=-Brazil, dk=Denmark, jp=Japan, nz=New Zealand, ru=Russian Federation, uk=United Kingdom, ch=Switzerland.
