The message — “LOGIN” — may have been short and simple‚ but it crashed the network anyway. The second computer only received the note’s first two letters. The network grows By the end of 1969‚ there were still only four computers connected to the ARPAnet. However‚ during the 1970s new local networks sprang up around the world‚ and the worldwide network grew steadily. There was a problem‚ though. As computer networks multiplied‚ it became more difficult to combine them into a single worldwide “Internet

Back in the early 1960s’‚ ARPANET was created by many sophisticated engineers‚ computer scientists‚ and mathematicians. The ARPANET design allowed computers to connect‚ run on different operating systems‚ and without ARPANET‚ the Internet wouldn’t look or behave the way it does today‚ it may not even exist. As technology advanced technicians began making advancements with combing the ARPANET network to the Satellite Network (SATNET). The technical term for

The Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks. It is commonly also known as TCP/IP named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. Modern IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely the Internet and local area networks

The internet‚ like every other innovation of the Digital Age‚ was not created by one lone person. There is much speculation about who should be considered the creator of the internet? Walter Isaacson brought a good point to my attention‚ What exactly is the internet? I couldn’t answer it. Few can. Isaacson brought forth solid evidence on why John Licklider should receive much of the credit on the creation of the internet. John Licklider was not a software expert by any means. He had a psychology

In 1968‚ a similar system was developed in the USA which went into operation at the US Defence Department’s Advanced Research Projects Agency (ARPA) in 1969. ARPA‚ also called ARPANET‚ used Network Control Protocol (NCP) as its transmission protocol from 1969 to 1982‚ when NCP was replaced with the now

Evolution Of Computers The term Computer‚ originally meant a person capable of performing numerical calculations with the help of a mechanical computing device. The foundation stone of the development of computers was laid way back in the era before Christ. Binary arithmetic is at the core of computer systems. History of computers dates back to the invention of a mechanical adding machine in 1642. ABACUS‚ an early computing tool‚ the invention of logarithm by John Napier and the invention of slide

Defense Department developed ARPAnet (Advanced Research Projects Agency network)‚ an experimental network of computers designed to withstand partial outages such as a bomb attack. The agency sought to create a web of computers that could continue to communicate with each other‚ even if some of the computers were disabled. In the mid-1980s‚ when desktop computer workstations became increasingly popular‚ organizations wanted to connect their local area networks (LANs) to ARPAnet. If computers could link
