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.

A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. WLAN utilizes spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network.

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."
