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) 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.
Megatokyo 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.
