 1983 Internet

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.
