What Is the Internet?

The Internet began as a project of the US Defense Department in the late 1960's. It was intended to link scientists working on defense and research projects around the country. During the 1980's, the National Science Foundation took over responsibility for the project and expanded the network to include the major universities and research sites in the United States. Links were then established to similar emerging networks in other countries. During the mid 1990's, the commercialization of the Internet began with the creations of dial-up services and was fueled by the creation of the World Wide Web.

It is important to understand that the Internet is not a single entity:

• The Internet is made up of many separate networks which are able to communicate with each other using standard languages or protocols.
• Each separate network is managed by its own network administration staff.
• The Internet works because all connected networks comply with a set of standards or protocols.
• There is no single governing body in charge of all the networks connected to the Internet.
• The Internet provides access to many services such as electronic mail, instant messaging, and the World Wide Web.

The Internet is an amazing example of cooperation and collaboration. There are many Internet guides available online which will provide more detail on the history of the Internet. Visit the Internet Navigator's Virtual Library for a list of online references.
