Where was Ethernet invented?
Palo Alto Research Center
Ethernet was created in 1973 by a team at the Xerox Corporation’s Palo Alto Research Center (Xerox PARC) in California. The team, led by American electrical engineer Robert Metcalfe, sought to create a technology that could connect many computers over long distances.
When did Robert Metcalfe invent the Ethernet?
May 22, 1973
The press has often stated that ethernet was invented on May 22, 1973, when Robert Metcalfe wrote a memo to his bosses stating the possibilities of ethernet’s potential, but Metcalfe claims ethernet was actually invented very gradually over a period of several years.
Who invented the Ethernet and when?
Metcalfe
In the 1960s and 1970s, networks were ad hoc hodgepodges of technologies with little rhyme and less reason. But then Robert “Bob” Metcalfe was asked to create a local-area network (LAN) for Xerox’s Palo Alto Research Center (PARC). His creation, Ethernet, changed everything.
Who Patented Ethernet?
History of Ethernet. On May 22, 1973, Bob Metcalfe (then at the Xerox Palo Alto Research Center, PARC, in California) wrote a memo describing the Ethernet network system he had invented for interconnecting advanced computer workstations, making it possible to send data to one another and to high-speed laser printers.
Who discovered LAN?
It has extended from the LAN into the wide area and wireless realms. Through technologies like switching and QoS controls, Ethernet has become the foundation technology for most networking communications today. Bob Metcalfe invented Ethernet in 1973 while at Xerox PARC, and the company patented it in 1975.
When was the first Ethernet cable made?
1974: Xerox PARC finishes developing the first ethernet cable, pioneered by Robert Metcalfe. 1975: Xerox files a patent for the ethernet cable. Metcalfe is listed as the inventor along with his colleagues David Boggs, Chuck Thacker, and Butler Lampson. 1976: The first ethernet system is privately deployed.
Who invented the Ethernet controller chip?
Robert Metcalfe and Ethernet Metcalfe was asked to build a networking system for PARC’s computers. Xerox’s wanted this set up because they were also building the world’s first laser printer and they wanted all PARC’s computers to be able to work with this printer. Metcalfe met with two challenges.
Who developed LAN technology?
Ethernet was developed at Xerox PARC between 1973 and 1974. ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977. It had the first commercial installation in December 1977 at Chase Manhattan Bank in New York.
Is Ethernet faster than WIFI?
Ethernet is typically faster than a Wi-Fi connection, and it offers other advantages as well. A hardwired Ethernet cable connection is more secure and stable than Wi-Fi. You can test your computer’s speeds on Wi-Fi versus an Ethernet connection easily.
What came before Ethernet?
Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches.

How did Robert Metcalfe invent the Ethernet network?
Robert Metcalfe invented, standardized, and commercialized Ethernet. Developed as a way to link the computers at Xerox’s Palo Alto Research Center (PARC) to one another, Ethernet uses digital packets and distributed controls to transmit data over what would become the most widely used local area network, or LAN.
Where did Robert Metcalfe build the first computer?
Robert Metcalfe was a member of the research staff at Xerox at their Palo Alto Ranch Center, where some of the first personal computers were made. Metcalfe was asked to build a networking system for PARC’s computers.
Who was the first person to invent Ethernet?
The press has often stated that Ethernet was invented on May 22, 1973 when Metcalfe wrote a memo to his bosses touting its potential. But Metcalfe claims Ethernet was actually invented very gradually over a period of several years.
What did Bob Metcalfe do for a living?
In 1979, Bob founded 3Com Corp, provider of Internet hardware and software, including the first commercial implementation of TCP/IP and the first Ethernet for PCs. 3Com went public in 1984, did $5.7 billion of revenue in 1999, and merged into Hewlett Packard in 2010. Dr. Metcalfe was a General Partner at Polaris Venture Partners from 2001-2010.
