The invention of the Internet by Vinton Cerf in 1973

The Internet is a worldwide network of thousands of computers and computer networks. This is a public effort, and voluntary cooperation between institutions and is not related owned or operated by a single organization. The Internet and Transmission Control Protocols were initially developed in 1973 by the American Vinton Cerf, a computer scientist in a project sponsored by the Ministry of Defence US Advanced Research Projects Agency (ARPA) and directed by the American engineer Robert Kahn.

Internet began to ARPA computer network (ARPANET), which refers to computer networks at several universities and research institutes in the United States. The World Wide Web was developed in 1989, English computer scientist Timothy Berners-Lee, the European Organization for Nuclear Research (CERN).

"The design of the Internet was made in 1973 and published in 1974, there were some 10 years of hard work, resulting in the spread of the Internet in 1983 Before that, a number of demonstrations of the technology has -.. as the first three interconnection network demonstrated in November 1977 linking SATNET, PRNet ARPANET and a path leading from Menlo Park, CA, University College London and return to the USC / ISI in Marina del Rey, CA .. "- Vinton Cerf says the timing:

The interconnection of computer networks on the Internet that enables connected machines to communicate directly. The term commonly refers, in particular, the global interconnection of government, education and information networks business, which is available to the public. Even the smallest of the internets, usually for a private organization, called an intranet.

Internet technology is a primitive precursor to the information superhighway, the theoretical goal of computer communications to provide schools, libraries, businesses and homes in order to ensure universal access to information that educates, informs and entertains. In early 1996 the Internet to each other for more than 25 million computers in over 180 countries and is growing significantly in price.

How Internet Work

Internet is formed by connecting the local network with dedicated computers on each network are known as gateways. Gateway connections made through various communication channels, including telephone lines, fiber optic and radio links. Networks can be added by connecting to new gateways. Information to be delivered to a remote machine is labeled with the computer address of the machine.

Different types of address formats used by various departments such as the Internet (see Internet address). Format is known as dotted decimal, for example: 123.45.67.89. Another format describes the name of the destination computer and other routing information, such as "machine.dept.univ.edu." Suffix at the end of the Internet address is the type of organization that owns the particular network, for example, education (. Edu), military sites (. Mil), government offices (. Gov), and nonprofit organizations (. org). Networking outside the U.S. States uses the suffix to indicate the country, for example (. CA) for Canada.

Once processed, the information leaves your home network through a gateway. That goes door to door until it reaches the local network that contains the target machine. Internets have no central control, ie not just computer directs the flow of information. This differentiates it from other internets of online services such as CompuServe, America Online and Microsoft Network.

Internet Protocol

Internet Protocol is the basic software to control the Internet. This protocol defines as the path to the gateway machines to send information on the host computer. Another protocol, Transmission Control Protocol, to see if the data has reached the target computer, otherwise, the data can be sent back.

Even if the entire computer is still in its infancy, has dramatically changed the world, bridging the barriers of time and distance, through which people can share information and work together. Evolution towards the information superhighway continues at an accelerated pace. The available content is growing rapidly, and then it is easier to find information on the Internet. New applications for secure transactions and providing new opportunities for trade. Speed ​​data transfer technology, which allows the direct transfer of on-demand entertainment. The television can be replaced by unicast, where every house is receiving a signal tailored to what the residents want to see when they want to see.
