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. atlast internet accessible to the general public.
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.

(born January 30, 1925 in Oregon
) is an American inventor
descent. As a World War II
naval radio technician
based in the Philippines
, Engelbart was inspired by Vannevar Bush
's article "As We May Think
". Engelbart received a Bachelor's degree
in electrical engineering from Oregon State University
in 1948, a B.Eng. from UC Berkeley
in 1952, and a Ph.D.
from UC Berkeley in 1955. At Stanford Research Institute
, Engelbart was the primary force behind the design and development of the On-Line System
, or NLS. He and his team at the Augmentation Research Center
developed computer-interface elements such as bit-mapped screens, groupware, hypertext
and precursors to the graphical user interface
. In 1967, Engelbart applied for and later received a patent
for the wooden shell with two metal wheels (computer mouse
). Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. He would also work on the ARPANET
, the precursor of the Internet
. In later years he moved to the private firm Tymshare after SRI was transferred to the company. McDonnell Douglas
took over the copany in 1982, and in 1986 he left the company. As of 2007, he is the director of his own company, the Bootstrap Institute, which founded in 1988 and located in Fremont, California
