![]() ![]() Metcalfe started 3Com to develop and sell Ethernet products. Other companies, such as IBM, adopted the token-passing scheme to battle Ethernet for LAN supremacy throughout the ‘80s. Transmitting signals instead of relying on random retransmission. While Ethernet employed collision-detection, ARC employed a token-passing scheme to avoid simultaneous transmissions by nodes. Unlike Metcalfe’sĮthernet, Datapoint’s LAN used the Attached Resource Computer (ARC) network. installed the first commercial LAN at Chase Manhattan Bank in New York. 1977: First commercial LANįour years later, Datapoint Corp. Wouldn’t respond and the nodes would then wait a random number of milliseconds to fire again. If nodes in the network fired at the same time, causing a collision, the mainframe It employed a collision-detection scheme. The Ethernet allowed computers to send packets of data through a coaxial cable to communicate with each other and the printer. Department of Defense- and the ALOHAnet, which was a packet-switching wireless radio network for computers developed by the University of Hawaii. Metcalfe’s idea was informed by ARPANET - the original internet developed by the U.S. InĪ memo, he named the networking method “Ethernet” because the huge coaxial cable that would connect the computers to each other reminded him of the Aether concept. His job was to network all the computers in a building to each other and to the world’s first Xerox laser printer. Here’s a timeline that will tell you why: 1973: Birth of the Ethernetĭr. However, it’s not far off to think about LAN and Aether in the same context. ![]() ![]() Not the 19th century concept of a mysterious, invisible medium between the sun and the Earth that conducts light - that’s Aether ![]()
