Today we would like to share abaout the 'History of internet'.
We hope that you guys will gain some knowledges and benefits from this entry :)
The Internet started in the 1960s as a way for government researchers to share information. Computers in the '60s were large and immobile and in order to make use of information stored in any one computer, one had to either travel to the site of the computer or have magnetic computer tapes sent through the conventional postal system.
Another catalyst in the formation of the Internet was the heating up of the Cold War. The Soviet Union's launch of the Sputnik satellite spurred the U.S. Defense department to consider ways information could still be disseminated even after a nuclear attack. This eventually led to the formation of the ARPANET (Advanced Research Projects Agency Network), the network that ultimately evolved into what we now know as the Internet. ARPANET was a great success but membership was limited to certain academic and research organizations who had contracts with the Defense Department. In response to this, other networks were created to provide information sharing.
January 1, 1983 is considered the official birthday of the Internet. Prior to this, the various computer sharing did not have a standard way to communicate with each other. A new communications protocol was established called Transfer Control Protocol/Internetwork Protocol (TCP/IP). This allowed different kinds of computers on different networks to "talk" to each other. ARPANET and the Defense Data Network officially changed to the TCP/IP standard on January 1, 1983. All networks could now be connected by a universal language.
| Year | Description |
|---|---|
| 1945-1969 (From simple, But significant Ideas Bigger Ones Grow) | - We can access information using electronic computers - We do it reliably with 'bits' sending and receiving data - We can do it cheaply by using Digital circuits etched in silicon - We can accomplish a lot by having a vast network of computers to use for accessing information and exchanging ideas - Packet switching can be used to send digitized data through computer networks - Hypertext can be used to allow rapid access to text data - We will prove that packet switching works over WAN |
| 1970s-1995 | - We need a protocol for Efficient and Reliable transmission of Packets over a WAN: TCP/IP - The ARPANET needs to convert to a standard protocol and be renamed to The Internet - Computers connected via the internet can be used more easily if hypertext links are enabled using HTML and URL's its called World Wide Web (WWW) - The World Wide Web is easier to use if we have a browser to browse a web pages, running in a graphical user interface context. - Great efficiencies can be accomplised if we used The Internet and World Wide Web to conduct business |
