计算机Internet的历史英文文献和翻译

更新时间:2014-5-30:  来源:毕业论文

The Internet started as a project by the US government. The object of the project was to create a means of communications between long distance points, in the event of a nation wide emergency or, more specifically, nuclear war. The project was called ARPAnet, and it is what the Internet started as. Funded specifically for military communication, the engineers responsible for ARPANet had no idea of the possibilities of an "Internet."
By definition, an 'Internet' is four or more computers connected by a network. 英语教学How to see the doctor案例
ARPAnet achieved its network by using a protocol called TCP/IP. The basics around this protocol was that if information sent over a network failed to get through on one route, it would find another route to work with, as well as establishing a means for one computer to "talk" to another computer, regardless of whether it was a PC or a Macintosh.
By the 80's ARPAnet, just years away from becoming the more well known Internet, had 200 computers. The Defense Department, satisfied with ARPAnets results, decided to fully adopt it into service, and connected many military computers and resources into the network. ARPAnet then had 562 computers on its network. By the year 1984, it had over 1000 computers on its network. 本文来自六.维,论-文·网原文请找腾讯752018766
In 1986 ARPAnet (supposedly) shut down, but only the organization shut
down, and the existing networks still existed between the more than 1000
computers. It shut down due to a failied link up with NSF, who wanted to
connect its 5 countywide super computers into ARPAnet.
With the funding of NSF, new high speed lines were successfully installed
at line speeds of 56k (a normal modem nowadays) through telephone lines
in 1988. By that time, there were 28,174 computers on the (by then decided) Internet. In 1989 there were 80,000 computers on it. By 1989, there were 290,000.
Another network was built to support the incredible number of people
joining. It was constructed in 1992.
Today - The Internet
Today, the Internet has become one of the most important technological advancements in the history of humanity. Everyone wants to get 'on line' to experience the wealth of information of the Internet. Millions of people now use the Internet, and it's predicted that by the year 2003 every single person on the planet will have Internet access. The Internet has truly become a way of life in our time and era, and is evolving so quickly its hard to determine where it will go next, as computer and network technology improve every day. 本文来自六.维,论-文·网原文请找腾讯324,9114
HOW IT WORKS:
It's a standard thing. People using the Internet. Shopping, playing games,conversing in virtual Internet environments.
The Internet is not a 'thing' itself. The Internet cannot just "crash." It functions the same way as the telephone system, only there is no Internet company that runs the Internet.
The Internet is a collection of millioins of computers that are all connected to each other, or have the means to connect to each other. The Internet is just like an office network, only it has millions of computers connected to it.
The main thing about how the Internet works is communication. How does a computer in Houston know how to access data on a computer in Tokyo to view a webpage?
Internet communication, communication among computers connected to the Internet, is based on a language. This language is called TCP/IP. TCP/IP establishes a language for a computer to access and transmit data over the Internet system. 2652
