What is Internet?
Short Internet history.
- The Internet was created by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1960's and was first known as the ARPANet.
- At this stage the Internet's first computers were at academic and government institutions and were mainly used for accessing files and to send email.
- Since 1983 the Internet has accommodated a lot of changes and continues to keep developing.
How does the Internet work?
- The Internet itself does not contain information, but is a network of networks, linking computers to computers sharing the TCP/IP protocols.
- Each runs software to provide or "serve" information and/or to access and view information.
- The Internet is the transport vehicle for the information stored in files or documents on another computer.
- It is a slight misstatement to say a "document was found on the Internet".
- It would be more correct to say it was found through or using the Internet.
- The content that was found in (or on) exists in one of the computers linked to the Internet.
