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.

Delrina was a Canadian software company based in Toronto, that existed between 1988 and 1995, prior to being bought by the American software firm Symantec. Delrina started out by producing a set of electronic form products known as PerForm and later, FormFlow. However, the company was best known for its WinFax software package of the early- to mid-1990s, which enabled computers equipped with fax-modems to communicate faxes to stand-alone fax machines or other similarly-equipped computers. Delrina also produced a set of popular screensavers, including one that resulted in the well-publicized "flying toasters" lawsuit for copyright and trademark infringement (Berkeley Systems Inc. v. Delrina); the case set a precedent in American law that satiric commercial software products were not subject to the same First Amendment exemptions as parodic cartoons or literature. After the buyout by Symantec in 1995, parts of the firm were sold off, while Symantec continues to sell the WinFax product to this day. In its wake, several of Delrina's former executives founded venture capital firms that continue to have a lasting impact on the Canadian software industry.

Voice over Internet Protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other packet switched networks. VoIP is often used abstractly to refer to the actual transmission of voice (rather than the protocol implementing it). VoIP is also known as IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband. "VoIP" is pronounced voyp.

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.

I mean, you go to the Internet and you can see all these conversations and arguments that our fans have about our music and that's wonderful to know, that people would take the time to be that involved.
Alex Lifeson, 1998
