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 Canadiansoftware 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.

Terry Semel (born on February 24, 1943 in Brooklyn, New York, U.S.A.) is an Americancorporate 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.

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!.
