What is the Internet?
The Internet is a loose collection of millions of computers at thousands of sites around the world which are linked together electronically so that they can all exchange information between themselves. It includes nearly every university, government, and research facility in the world, yes the world.
Ironically, the Internet was developed by the Defense Department as a means of safe-guarding the capacity to make war. It began as an experiment in the late 1960's to test the possibility of creating a disaster-proof nationwide computer system where scientists and military personnel could share messages and data no matter where they were. The fear was that in a nuclear war, most systems would fail. Even the most protected environments could not completely safeguard continued operations. By having all the systems interconnected but acting independently, one one, which survived could still share data and messages with any others still operational. This resulted in the development of a highly decentralized connection system unlike most military systems which are based on tight top down centralized command and control systems.
This ability to communicate widely and openly was found so useful by scientists that the National Science Foundation funded its continued development. Special high speed telephone lines were put in place to link these machines together. It was originally called the inter-network and as it grew around the world became known as the Internet.
No one person or group runs the Internet. Each site decides independently to sign on to the larger system. The Internet is overseen by a council of elders, called the Internet Society which sets connection standards and concerns itself with technological issues. No one pays to belong to the Internet. Each organization, network or individual pays its own way. Somehow it all works.
