The Internet Portal

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). 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.

Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle using a Wi-Fi-equipped computer, such as a laptop or a PDA. It is similar to using a radio scanner, or to the amateur radio practice of DXing.

Selected biography

Chad Hurley in 2007
Chad Meredith Hurley (born 1977) is co-founder and Chief Executive Officer of the popular San Bruno, California-based video sharing website YouTube, one of the biggest providers of videos on the Internet. In June 2006, he was voted 28th on Business 2.0's "50 people who matter" list. In October 2006 he sold YouTube for $1.65 billion to Google. Hurley worked in eBay's PayPal division before starting YouTube with fellow PayPal colleagues Steve Chen and Jawed Karim. One of his tasks at eBay involved designing the original PayPal logo. Newsweek describes Hurley as a user interface expert. He was primarily responsible for the tagging and video sharing aspects of YouTube. YouTube was born when the founders (Hurley, Chen, and Karim) wanted to share some videos from a dinner party with friends in San Francisco in January 2005. Sending the clips around by e-mail was a bust: The e-mails kept getting rejected because they were so big. Posting the videos online was a headache, too. So they got to work to design something simpler. In 11 months the site became one of the most popular sites on the Internet because the founders designed it so people can post almost anything they like on YouTube in minutes.

Like anything else, you can use the internet for good or ill. You can get out of it what you want to. There's no evil about it. The way I see it, it's a liberation.
