ROOTS OF INTERNENT.
The Internet has its roots in a networking project started by an agency of the U.S Department of Defense. The goal was to build a network that  allowed scientists at different locations to share information and work together on military and scientific projects and  could function even if part of the network were disabled or destroyed by a disaster such as a nuclear attack.That network called ARPANET, became functional in September 1969,linking scientific and academic researchers across the United States. The original ARPANET consisted of four main computers, one each located at the University of California at Los Angeles, the University of California at Santa Barba, the Stanford Research Institute, and the University of Utah. Each of these computers served as a host on the network. A host or server is any computer that provides services and connections to other computers on a network. By 1984,ARPANET had more than 1,000 individual computers linked as hosts.Today,more than 550 million hosts connect to this network, which is known as the Internet. The Internet consists of many local,regional,national,and international networks. Both Public and Private organizations own networks on the internet. The World Wide Web consortium (W3C),however, oversees research and sets standards and guidelines for many areas of the Internet. More than 350 organizations from around the world are members of the W3C.

- A Wi-Fi (Wireless fidelity) network uses radio signals to provide high speed Internet connections to wireless computers and devises.
- A cellular radio Network offers high-speed Internet connections to devices with built-in compatible technology or computers with wireless modems.
- Satellite Internet Service provides high-speed Internet connections via satellite to a satellite dish that communicates with a satellite modem.
Many home users set up a Wi-Fi network, which sends signals to a communication device that is connected to a high-speed Internet such as cable or DSL.
