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.

Map of the early internet in 1982.
The history of the Internet dates back to the early development of communication networks. In the 1950s and early 1960s, prior to the widespread inter-networking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network. Some networks had gateways or bridges between them, but these bridges were often limited or built specifically for a single use. One prevalent computer networking method was based on the central mainframe method, simply allowing its terminals to be connected via long leased lines. This method was used in the 1950s by Project RAND to support researchers such as Herbert A. Simon, in Pittsburgh, Pennsylvania, when collaborating across the continent with researchers in Santa Monica, California, on automated theorem proving and artificial intelligence.

A blog (a portmanteau of web log) is a website where entries are commonly displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog. Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic.

Selected biography

Terry Semel at the Web 2.0 Conference 2005
Terry Semel (born on February 24, 1943 in Brooklyn, New York, U.S.A.) is an American corporate executive who was the chairman and CEO of Yahoo! Incorporated. Previously, Semel spent 24 years at Warner Brothers, where he served as chairman and co-chief executive officer. In June 2007, Semel resigned as CEO due in part to pressure from shareholders dissatisfaction over Semel's compensation (in 2006 - salary $1, stock options worth $70 million) and performance. Semel had earned over $500 million in his tenure at Yahoo, while Yahoo's stock appreciated at 5% per year. In the same period, Yahoo's closest competitor saw stock growth of over 400%. Semel now serves as non-executive chairman and advisor to Yahoo!.

Cyberspace may give freedom of speech more muscle than the First Amendment does. It may already have become literally impossible for a government to shut people up.
