Networked computers bring together many independent students in science and engineering such as communications, computer science, information technology, and / or computer engineering. Computers are connected to each other primarily through telecommunications. Telecommunications, in turn, can be operated using computers and in both wired and wireless media. To reach the sophisticated technological precision of the hardware, including computers, used in building computer networks, the efficiency of information technology and computer science has been supported.
The chronology of the evolution of computer networks
Even before the nineteenth century AD, visual signs were believed to be used in communication. Communication between the calculating machines used is by manually passing instructions. The development of current computer networks can be traced back to the middle of the last century. Chronologically, it can be described as follows:
September 1940 – George Stibitz used the teletype device to send instructions for a problem with a range of his model from Dartmouth College in New Hampshire to a complex number calculator in New York and receive return results.
August 1962 Computer scientist JCR Licklider from Bolt, Beranek and Newman Company formulated and published the concept of connecting output systems such as teletypes to computers for the design of the "Intergalactic Computer Network".
October 1963 – The Advanced Research Projects Agency (ARPA) has appointed JCR Licklider to design and develop the ARPANET network for the US Department of Defense to share resources and information.
1964 Researchers have developed the Dartmouth Time Sharing System for discrete computer systems in Dartmouth. In the same year, a group of researchers at MIT successfully guided and managed the phone using computers. This project is supported by General Electric and Bell Labs.
1965 Lawrence J. Roberts and Thomas Merrill succeeded in creating the first wide area network (WAN). In the same year, the first PSTN (Public Switched Telephone Network) switch was introduced widely by Western Electric. It was important because he used real computer control for networks for the first time in history.
November 1969 – The first permanent ARPANET link was created between the Interconnection Wizard (IMP) at the University of California, Los Angeles (UCLA) and the IMP at the Stanford Research Institute.
December 1969 The four-point network was linked with the University of California, Santa Barbara, UCLA, the Stanford Research Institute and the Department of Computer Science at the University of Utah on both nodes.
1972 – Commercial services using X.25 were deployed in, and subsequently used as the primary infrastructure for expansion of Transmission Control Protocol / IP Protocol networks.
1989 Timothy Berners-Lee invented the European Laboratory of Particle Physics in Geneva, Switzerland.
Ongoing efforts to communicate through and network with computer networks as well, technologies have evolved by increasing computers, software, and peripheral industries. As a result, the scope of multi-faceted communication has evolved. This development would have been impossible without progress in the computer network.
