The Internet PortalThe 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.

The history of the Internet dates back to the early development of communication networks. In the 1950s and early 1960s, prior to the widespread inter-networking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network. Some networks had gateways or bridges between them, but these bridges were often limited or built specifically for a single use. One prevalent computer networking method was based on the central mainframe method, simply allowing its terminals to be connected via long leased lines. This method was used in the 1950s by Project RAND to support researchers such as Herbert A. Simon, in Pittsburgh, Pennsylvania, when collaborating across the continent with researchers in Santa Monica, California, on automated theorem proving and artificial intelligence.
Selected pictureWi-Fi (/ˈwaɪfaɪ/ wye-fye) is a wireless technology brand owned by the Wi-Fi Alliance intended to improve the interoperability of wireless local area network products based on the IEEE 802.11 standards. Common applications for Wi-Fi include Internet and VoIP phone access, gaming, and network connectivity for consumer electronics such as televisions, DVD players, and digital cameras.

Selected biography
Vannevar Bush (March 11, 1890 – June 30, 1974) was an American engineer and science administrator, known for his work on analog computing, his political role in the development of the atomic bomb, and the idea of the memex—seen as a pioneering concept for the World Wide Web. A leading figure in the development of the military-industrial complex and the military funding of science in the United States, Bush was a prominent policymaker and public intellectual ("the patron saint of American science") during World War II and the ensuing Cold War. Through his public career, Bush was a proponent of democratic technocracy and of the centrality of technological innovation and entrepreneurship for both economic and geopolitical security.
