You probably know that the first computer was made in 1943, which is called ENIAC. Although this computer was primarily designed, it was for the United States Army to calculate the amount of ammunition in the battlefield. His weight was around 27 tons, and around 1800 square feet was needed to keep it.
Until 1950, a number of computers were created in the world, each of which was very big and very expensive. Generally, these computers were used in very large universities and research institutes or government institutions. The work of computers was mainly to assist in calculating, to save information. From that time researchers began to feel the necessity of transmitting information from one computer to another computer. Then the United States defense research institute Darpa (DARPA) started research on this topic. At that time computer networking ideas were ready. Researchers offer various theories.
In 1964, MIT researcher Leonard Kleinrock introduced a concept called packet switching and published a paper on it.
In 1965, researchers were able to connect two computers with a network for the first time.
In 1967, MIT researcher Lawrence G. Roberts, who later joined Darpa, proposed a network system called ARPANET. The key point of his research paper was how to transfer data between two computers using packet switching, which would allow the military to disassemble all the other communications during wartime.
In 1968, the creative design of the aphanite was made by Darpa’s financing. The proposed lineship in this design was 50 kbps. The first computer or node is set to be attached to this apparatus in the University of California (UCLA) in Los Angeles. The second node was installed at the Stanford Research Institute. Later, two more nodes were placed at the University of California (UC Santa Barbara) in Santa Barbara and in the University of Utah. Here each computer connected to the network is called host computer.
By the end of 1969, these four hosts were connected to ComputerApnet. This is the first effective network of computer history, based on which the Internet is started.
