The Internet Portal

An Internet kiosk

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.

Wikimania, annual conference for users of Wikipedia and other Wikimedia projects
Wikipedia is a multilingual, open content, free encyclopedia project operated by the non-profit Wikimedia Foundation. Its name is a portmanteau of the words wiki (a type of collaborative website) and encyclopedia. Launched in 2001, it is the largest, fastest growing and most popular general reference work currently available on the Internet. As of December 2007, Wikipedia had approximately 9 ¼ million articles in 253 languages, comprising a combined total of over 1.41 billion words for all Wikipedias. The English Wikipedia edition passed the 2,000,000 article mark on September 9, 2007. Wikipedia's articles have been written collaboratively by volunteers around the world and the vast majority of them can be edited by anyone with access to the Internet. Critics have questioned Wikipedia's reliability and accuracy, citing its open nature. The criticism is centered on its susceptibility to vandalism, such as the insertion of profanities or random letters into articles, and the addition of spurious or unverified information; uneven quality, systemic bias and inconsistencies; and for favoring consensus over credentials in its editorial process. Scholarly work suggests that vandalism is generally short-lived. When Time Magazine recognized "You" as their Person of the Year 2006, Wikipedia was the first particular "Web 2.0" service mentioned, followed by YouTube and MySpace.
