Internet History Essays (911 words) - ARPANET, Digital Technology
  Internet History  The Internet was created in 1969 by scientists working for ARPA. ARPA stands for  advanced research projects agency, and was formed to create a network of  computers that could save information in the event of a nuclear attack. UCLA,    Stanford Research Institute (SRI), UC Santa Barbara (UCSB), and the University  of Utah in Salt Lake City were the first ARPANET locations. The ARPANET is what  is now called the Internet. The plan was unprecedented: A professor at UCLA, and  his small group of graduate students hoped to log onto the Stanford computer and  try to send it some data. They would start by typing "login," and  asking by telephone if the letters appeared on the far-off monitor. On their  first attempt, the "L" and "O" were transmitted successfully, but after  they typed the letter "G" the system crashed. From 1969 to 1983 a lot of  different packet switching schemes were tried and TCP/IP is what grew OUT of    ARPANET, not what started ARPANET. During most of the seventies, the protocol  was generally referred to as just the Network Control Protocol or NCP. The term    Internet was probably first applied to a 1973 research program that culminated  in a demonstration system in 1977. It demonstrated networking through various  mediums, including satellite, radio, telephone, ethernet, etc. using packet  switching. And this formed the roots of the Transmission Control Protocol and    Internet Protocol (TCP/IP). But it was not until 1983 that all nodes on ARPANET  were required to use TCP/IP to connect to it. Also in 1983, the Department of    Defense moved the unclassified portions of the Data Defense Network to create    MILLET. Then in January 1983, the ARPA Internet first appears and operation was  passed to the Defense Communications Agency. The first operating,  non-experimental, real live Internet with a capital network, was a military  network with a couple of hundred computers connected to it. Universities and the  general public were not welcome on the ARPANET. It was a network for Department  of Defense contractors and military sites. Then a group of military contractors  with strong ties to business and universities not on the MILLET were constantly  in a situation where many of their peers were not on the Net while they were on.    They began campaigning for access for other researchers. In 1984 the National    Science Foundation established an office for networking. a number of  universities and research groups actually did get access to ARPANET. In 1993,    Tim Lee created an interface to the World Wide Web he called Mosaic. The NSF  actually funded further development of a Macintosh and Microsoft Windows version  of Mosaic through a grant to the University. The first Microsoft Windows version  appeared about November of 1993. The Mosaic Web Browser put a pretty face on the    Internet. You could navigate the World Wide Web by clicking on links with the  mouse. More importantly, it allowed users to add "players" for sound,  video clips, or anything else they wanted to add. Today, advanced Mosaic  browsers such as Netscape have added other functions quite beyond World Wide    Web, including electronic mail. Electronic mail, or E-mail as it is commonly  called, was invented by Ray Tomlinson in 1971 as a way of sending messages of  the Internet to other users on-line. His program for sending E-mail was called    SNDMSG, which stands for send message. Now E-mail has grown so much that next  year people will send an estimated 6 trillion messages. A new use for the    Internet that is influencing the lives of many Internet users is the creation of    E-wrestling leagues. E-wrestling is a type of game in which you create wrestling  matches over E-mail. You can challenge other members of your E-fed (a group of  members in your league) by posting messages on the message board. The other  member will then respond to your challenge by writing back on the message board.    If the commissioner approves of the match then he will send an E-mail to the two  members telling when the match will take place. There are two ways a  commissioner can create matches, depending on the rules of your federation. One  way is to write out the entire match. This takes a long time and the results are  based on the opinion of the commissioner. The other way involves using a  computer to decide the winner. My federation uses "Zeus", a computer program  found on the Internet, to simulate the matches. The good thing about this type  of match is it can be made quickly, the matches are fair and based on wrestlers  attributes,
