Portal:Internet
The Internet Portal The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia in the 1980s, commercialization incorporated its services and technologies into virtually every aspect of modern life. Most traditional communication media, including telephony, radio, television, paper mail and newspapers are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, and video streaming websites. Newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking. Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online. Business-to-business and financial services on the Internet affect supply chains across entire industries. The Internet has no single centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own policies. The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders. Selected articleMegatokyo is an English-language webcomic created by Fred Gallagher and Rodney Caston, debuting on August 14, 2000, and then written and illustrated solely by Gallagher as of July 17, 2002. The style of its writing and illustrations is heavily influenced by Japanese manga. Megatokyo is freely available on its official website, with updates on Monday, Wednesday, and Friday. It is among the most popular webcomics, and is published in print by CMX. Sales of the comic's print editions rank it as the best selling original English-language manga. Set in a fictional version of Tokyo, Megatokyo portrays the adventures of Piro, a young fan of anime and manga, and his friend Largo, a video game enthusiast. The comic often parodies and comments on the archetypes and clichés of anime, manga, dating simulations and video games, occasionally making direct references to real-world works. Megatokyo was originally presented in the gag-a-day format, with continuity of the story a subsidiary concern. Over time, it focused more on developing a complex plot and the personalities of its characters. This transition was due primarily to Gallagher's increasing control over the comic, which led to Caston's controversial removal from the project. Megatokyo has received praise from such sources as The New York Times, while negative criticism of Gallagher's changes to the comic has been given by sources including Websnark. Selected picture Webcams are small cameras, (usually, though not always, video cameras) whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion. News
