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.

moot, founder of 4chan
4chan is an English-language imageboard website based on the Japanese-language Futaba Channel. Launched on October 1, 2003 by "moot" ("Christopher Poole"), its boards are based primarily around the posting of pictures and discussion of Japanese comics and television shows. Users generally post anonymously, and the site has been linked to "Anonymous" culture and Project Chanology. 4chan's "/b/" board, dedicated to random postings, is the most active and is notorious on the Internet. The site has generated significant media attention, and its members have been responsible for the formation and popularization of several Internet memes such as lolcats, rickrolling, and the popularity of the Tay Zonday song "Chocolate Rain". It has also received media attention for its attacks against other websites and Internet users, and for the threats of real world violence that have been posted on it.

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

Vint Cerf in 2007
Vinton Gray Cerf (born June 23, 1943) is an American computer scientist who is the "person most often called 'the father of the Internet'." His contributions have been recognized repeatedly, with honorary degrees and awards that include the National Medal of Technology, the Turing Award, and the Presidential Medal of Freedom. Cerf's first job after getting his B.S. in mathematics from Stanford University was at IBM, where he worked for less than two years as a systems engineer supporting QUIKTRAN. He left IBM to become a principal programmer at UCLA; he then became an assistant professor at Stanford University where he co-designed the Department of Defense TCP/IP protocol suite with Robert E. Kahn. Cerf joined the board of the Internet Corporation for Assigned Names and Numbers (ICANN) in 1999, and is serving a term until the end of 2007; he previously served as the ICANN Chair.

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.
