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.

Screenshot of ScienTOMogy from November 2005
ScienTOMogy was a parody web site lampooning Tom Cruise's involvement with Scientology, initially hosted at the domain name scientomogy.info. The site was created in 2005 after increased media publicity surrounding Cruise's appearances on The Oprah Winfrey Show and The Today Show. ScienTOMogy gained press attention after it was contacted by the Church of Scientology with a cease and desist letter, alleging copyright infringement over use of the word "Scientomogy", claiming that it was too close to the word "Scientology". The proprietor of the site initially agreed to relent to the Church's demands, but after consulting attorneys, instead decided to keep the site. Internet traffic to the site later increased dramatically as a result of the media and press attention surrounding the Church of Scientology's alleged copyright infringement claims.

Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle using a Wi-Fi-equipped computer, such as a laptop or a PDA. It is similar to using a radio scanner, or to the amateur radio practice of DXing.

Selected biography

Al Gore, Official portrait, 1994
Albert Arnold "Al" Gore, Jr. (born March 31, 1948) was the forty-fifth Vice President of the United States, serving from 1993 to 2001 under President Bill Clinton. Gore previously served in the U. S. House of Representatives (1977–85) and the U. S. Senate (1985–93), representing Tennessee. He was the Democratic Party presidential nominee in the 2000 election, and shared the 2007 Nobel Peace Prize with the Intergovernmental Panel on Climate Change for his work as an environmental activist. Gore has been involved with the development of the Internet since the 1970s, first as a Congressman and later as Senator and Vice-President. His High Performance Computing and Communication Act of 1991 (often referred to as the Gore Bill) was passed on December 9, 1991 and led to the National Information Infrastructure (NII) which Gore referred to as the "information superhighway." Leonard Kleinrock, a key player in the development of the ARPANET, considers the act to be a critical moment in Internet history. Internet pioneers Vint Cerf and Bob Kahn stated in the 2000 article "Al Gore and the Internet", that Gore was "the first political leader to recognize the importance of the Internet and to promote and support its development."

Nobody who wasn't a high-energy physicist had even heard of the World Wide Web before I became President. And now even my cat, Socks, has his own page.
