Web navigation
Web navigation came about with the introduction of the World Wide Web, in 1989 when Timothy Berners-Lee invented it. Once the world wide web was available, web navigation increasingly became a major aspect and role in jobs and everyday lives. With one-third of the world’s population now using the internet, web navigation maintains a global use in today's ever evolving international society. Web navigation is not restricted to just computers, either, as mobile phones and tablets have added avenues for access to the ever-growing information on the web today. The most recent wave of technology which has affected web navigation is the introduction and growth of the smartphone. As of January 2014, 58% of American adults owned a smart phone, and that number is on the rise from previous years. Web navigation has evolved from a restricted action, to something that many people across the world now do on a daily basis.
Timeline of United States inventions (1946–1991)
Not to be confused with a separate application known as the World wide web which was invented much later in the early 1990s (see article on the English inventor Tim Berners-Lee), the Internet is the global system of overall interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists 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 concept of packet switching of a network was first explored by Paul Baran in the early 1960s, and the mathematical formulations behind packet switching were later devised by Leonard Kleinrock. On October 29, 1969, the world's first electronic computer network, the ARPANET, was established between nodes at Leonard Kleinrock's lab at UCLA and Douglas Engelbart's lab at the Stanford Research Institute (now SRI International). Another milestone occurred in 1973 when Bob Kahn and Vinton Cerf co-invented Internet Protocol and Transmission Control Protocol while working on ARPANET at the United States Department of Defense. The first TCP/IP-wide area network was operational on January 1, 1983, when the United States' National Science Foundation (NSF) constructed the university network backbone that would later become the NSFNet. This date is held as the "birth" of the Internet.
