Internet

Internet is a global network of interconnected computers, enabling users to share information along multiple channels. Typically, a computer that connects to the Internet can access information from a vast array of available servers and other computers by moving information from them to the computer's local memory. The same connection allows that computer to send information to servers on the network; that information is in turn accessed and potentially modified by a variety of other interconnected computers.

Overview

The Internet consists of a vast number of networks that came about from many different organizations, individuals and governments, all of which are now interconnected. It is decentralized by design, as there is no central governing body that oversees how it is operated or what its policies are. The Internet is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body with each constituent network setting and enforcing its own policies.

History

The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s.

Uses

The Internet carries a vast array of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

Internet Access

Internet access is the process of connecting to the internet using personal computers, laptops or mobile devices by users or enterprises. Internet access is subject to data signal strength and an ISP subscription. It is also dependent on the quality of signal provided by the ISP.
