Ethernet Prototype Circuit Board

Ethernet Prototype Circuit Board

<< >>
Description
This Ethernet board is a prototype developed by Robert Metcalf in 1973 while at Xerox Palo Alto Research Center (PARC). Metcalf based his idea for the Ethernet on the ALOHAnet, a packet-switching wireless radio network developed by Norman Abramson, Frank Kuo, and Richard Binder at the University of Hawaii-Manoa. The ALOHAnet sent computer data communication between the university's campuses on several islands. Metcalf improved upon ALOHAnet's design and created the "Alto ALOHA Network," a network of computers hard-wired together by cables that he soon called the Ethernet. In 1985, the Ethernet became the
Institute of Electrical and Electronics Engineers, Inc. (IEEE) standard for connecting personal computers via a Local Area Network (LAN). Today, LANs often use WiFi, or Wireless Fidelity, a way of connecting computers without wires.
