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.

"On the Internet, nobody knows you're a dog" is an adage which began as the caption of a famous cartoon published by The New Yorker on 5 July 1993, and authored by Peter Steiner. The cartoon shows two dogs: One sitting on a chair in front of a computer, speaking the caption to a second dog sitting on the floor. As of 2000, the panel was the most reproduced cartoon from The New Yorker, and Steiner had earned over $50,000 (USD) from the reprinting of the cartoon.

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

J. C. R. Licklider
Joseph Carl Robnett Licklider (March 11, 1915 - June 26, 1990), known simply as J.C.R. or "Lick" was an American computer scientist, considered one of the most important figures in computer science and general computing history. After early work in psychoacoustics, he became interested in information technology early in his career. Much like Vannevar Bush, J.C.R. Licklider's contribution to the development of the Internet consists of ideas, not inventions. He foresaw the need for networked computers with easy user interfaces. His ideas foretold of graphical computing, point-and-click interfaces, digital libraries, e-commerce, online banking, and software that would exist on a network and migrate wherever it was needed. Licklider was instrumental in conceiving, funding and managing the research that led to modern personal computers and the Internet. His seminal paper on Man-Computer Symbiosis foreshadowed interactive computing, and he went on to fund early efforts in time-sharing and application development, most notably the work of Douglas Engelbart, who founded the Augmentation Research Center at Stanford Research Institute and created the famous On-Line System. He played a similar role in conceiving of and funding early networking research, most notably the ARPAnet.
