The Internet is a global system of interconnected computer networks, consisting of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet appears to its users as a single worldwide network accessible to the general public. The protocol that makes it possible to use the millions of networks composing the Internet as if they were one network is a special type of packet switching known as IP or The Internet Protocol.

A computer that connects to the Internet can access information from a vast number of servers and other computers. An Internet connection also allows the computer to send information through the network; that information may be saved and ultimately accessed by a variety of servers and other computers. Much of the information widely accessible through use of the Internet consists of the interlinked hypertext documents and other resources of the World Wide Web (WWW). Web users typically send and receive information using a web browser. Other software for interacting with computer networks includes specialized programs for electronic mail, online chat, file transfer and file sharing.

Information is moved around the Internet by packet switching using the standardized Internet Protocol Suite (TCP/IP)which defines how packets are moving in any platform especially the transport layer. The Internet Protocol Suite consists of several layers of protocols. The lowest layer (the link layer) deals with protocols that transmit data over specific technologies, such as Ethernet or Wi-Fi. The highest layer (the application layer) supports specific applications, such as e-mail and file transfer. In between are the Internet layer, which provides for transmitting packets over any conceivable technology, and the transport layer, which provides for various services such as reliable delivery of packets or real-time streaming of packets.

YouTube headquarters in San Bruno
YouTube is a video sharing website where users can upload, view and share video clips. YouTube was created in mid-February 2005 by three former PayPal employees. The San Bruno-based service uses Adobe Flash technology to display a wide variety of video content, including movie clips, TV clips and music videos, as well as amateur content such as videoblogging and short original videos. In October 2006, Google Inc. announced that it had reached a deal to acquire the company for US$1.65 billion in Google stock. The deal closed on November 13, 2006. Unregistered users can watch most videos on the site, while registered users are permitted to upload an unlimited number of videos. Some videos are available only to users of age 18 or older (e.g. videos containing potentially offensive content). The uploading of pornography or videos containing nudity is prohibited. Related videos, determined by title and tags, appear onscreen to the right of a given video. In YouTube's second year, functions were added to enhance user ability to post video 'responses' and subscribe to content feeds. Few statistics are publicly available regarding the number of videos on YouTube. However, in July 2006 the company revealed that more than 100 million videos were being watched every day, and 2.5 billion videos were watched in June 2006.

In computer networking, a wireless access point (WAP or AP) is a device that connects wireless communication devices together to form a wireless network. The WAP usually connects to a wired network, and can relay data between wireless devices and wired devices. Several WAPs can link together to form a larger network that allows "roaming".

Selected biography

Photo by Irene Fertik, USC News Service. Copyright 1994, USC
Jonathan Bruce Postel (6 August 1943 – 16 October 1998) made many significant contributions to the development of the Internet, particularly in the area of standards. He is principally known for being the Editor of the Request for Comment (RFC) document series, and for serving as the Internet Assigned Numbers Authority until his death. While studying at UCLA, he was involved in early work on the ARPANET; he later moved to the Information Sciences Institute at the University of Southern California, where he spent the rest of his career. Postel served on the Internet Architecture Board and its predecessors for many years. He was the original and long-time .us Top-Level Domain administrator. He also managed the Los Nettos Network. The Internet Society's Postel Award is named in his honor, as is the Postel Center at Information Sciences Institute.

By 1996, there was enough material on the Internet to show that this thing was the cornerstone for how people are going to be publishing. It is the people's library.
