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.

WikiWorld comic, by Greg Williams
Exploding whales have been documented on two notable occasions, as well as several lesser-known ones. The most famous explosion occurred in the United States at Florence, Oregon, in 1970, when a dead sperm whale (originally reported as a gray whale) was blown up by the Oregon Highway Division in an attempt to dispose of its rotting carcass. This incident became famous in the U.S. when American humorist Dave Barry wrote about it in his newspaper column after viewing a videotape of television footage of the explosion. It later became well-known internationally when the same footage circulated on the Internet. There have also been spontaneous explosions. The other best-reported case of an exploding whale was in Taiwan in 2004, when a buildup of gas inside a decomposing sperm whale caused it to explode while it was being transported for a post-mortem examination. As exploding whales are an interesting and absurd topic, they have been written about by several authors.

Webcams are small cameras, (usually, though not always, video cameras) whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion.

Selected biography

Douglas C. Engelbart
Douglas C. Engelbart (born January 30, 1925 in Oregon) is an American inventor of Swedish and Norwegian descent. As a World War II naval radio technician based in the Philippines, Engelbart was inspired by Vannevar Bush's article "As We May Think". Engelbart received a Bachelor's degree in electrical engineering from Oregon State University in 1948, a B.Eng. from UC Berkeley in 1952, and a Ph.D. in EECS from UC Berkeley in 1955. At Stanford Research Institute , Engelbart was the primary force behind the design and development of the On-Line System, or NLS. He and his team at the Augmentation Research Center developed computer-interface elements such as bit-mapped screens, groupware, hypertext and precursors to the graphical user interface. In 1967, Engelbart applied for and later received a patent for the wooden shell with two metal wheels (computer mouse). Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. He would also work on the ARPANET, the precursor of the Internet. In later years he moved to the private firm Tymshare after SRI was transferred to the company. McDonnell Douglas took over the copany in 1982, and in 1986 he left the company. As of 2007, he is the director of his own company, the Bootstrap Institute, which founded in 1988 and located in Fremont, California.

I mean, you go to the Internet and you can see all these conversations and arguments that our fans have about our music and that's wonderful to know, that people would take the time to be that involved.
