INTERNET
Internet, In Today life internet is a very common thing for normal people and today I am going to express about how internet starts and who is inventors of internet
Internet!
The "network of networks" that connect computers throughout the world has its origins in a problem that arose as the machines became more sophisticated ; How can many users in a large organization share computational power? Programmers figured out how to break information into small packets that could be routed through different available circuits, and ever faster computers resembled the packets more and more quickly.
The defense and the airline industries first look advantage of networks in the 1950s with the pentagon adopting a new computer based command and control system and American airlines teaming with IBM on the Sabre passenger reservation system.
In 1969 the Defense advanced Research Projects Agency (DARPA) established the advanced research projects network , ARPANET, the precursor to todays internet. Through ARPANET major US government and information. ARPANET programmers developed packet switching and other basic tools for sending messages and transferring files , such as simple mail transfer protocol (STMP) and file Transfer protocol (FTP).
In the 1970s, DARPA commissioned work on " internetting" that is communication among computer networks. Researches Vinton Cerf and Robert Kahn developed two important methods: the transmission control protocol (TCP), which established rules for collecting and reassembling data packets, and the internet protocol (IP), which routed data to the correct dresses for interconnected machines.
In the 1980s, the other government agencies and universities began tapping into the system . The National Sound foundation founded supercomputing centers at five universities with a so called backbone connecting them nationally. Gradually the system opened up to commercial networks which now largely oversea a connection of regional network access point (NAPs). The exploding set of numbered addresses , meanwhile, is administered by the non profit internet Corporation For Assigned Names and Numbers.
As access expanded so did ease of use. Swiss researcher Tim Berners-Lee Developed hypertext transfer protocol (HTTP) in the early 1990s, which allowed various elements - graphics, imagery, and text-to be collected to together into a "page" with links and references to other pages. Pages accessible through this growing World Wide Web were identified by a textual label called a universal resource locator (URL) . At the university of Illinois, Marc Andreesen developed Mosaic, the worlds first Web "browser" - software by which computer users can view pages and navigate the internet with the use of a computer mouse.
