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.

Cyberpunk is often set in urbanized, artificial landscapes
Cyberpunk is a genre of science fiction that focuses on computers or information technology, usually coupled with some degree of breakdown in social order. The plot of cyberpunk writing often centers on a conflict among hackers, artificial intelligences, and mega corporations, tending to be set within a near-future dystopian Earth, rather than the "outer space" locales prevalent at the time of cyberpunk's inception. Much of the genre's "atmosphere" echoes film noir, and written works in the genre often use techniques from detective fiction. While this gritty, hard-hitting style was hailed as revolutionary during cyberpunk's early days, later observers concluded that in terms of literature, most cyberpunk narrative techniques were less innovative than those of the New Wave, twenty years earlier. Primary exponents of the cyberpunk field include William Gibson, Bruce Sterling, John Shirley and Rudy Rucker. The term became widespread in the 1980s and remains current today.

A hotspot is a venue that offers Wi-Fi access. The public can use a laptop, WiFi phone, or other suitable portable device to access the Internet. Of the estimated 150 million laptops, 14 million PDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature.
