C. San Diego Lines: 32 Quoting Andrew Tanenbaum: The IEEE 802.3 standard is for a 1-persistent CSMA/CD LAN. [stuff deleted] The 802.3 standard has an interesting history. The real beginning was Abramson's ALOHA system in Hawaii, to be discussed later in this chapter. Later, carrier sensing was added, and Xerox built a 2.94-Mbps CSMA/CD system to connect over 100 personal workstations on a 1-km cable (Metcalfe and Boggs, 1976; Schoch, 1987). This system was called Ethernet after the luminiferous ether, through which electromagnetic radiation was once thought to propagate. [stuff deleted] The Xerox Ethernet was so successful that Xerox, DEC, and Intel drew up a standard for a 10-Mbps Ethernet. This standard formed the basis for 802.3. The published 802.3 standard differs from the Ethernet specification in that it describes a whole family of 1-persistent CSMA-CD systems, running at speeds from 1 to 10 Mbps on various media. [stuff deleted] Many people (incorrectly) use the name "Ethernet" in a generic sense to refer to all CSMA/CD protocols, even though it really refers to a specific product that implements 802.3. Quoted from the second edition of _Computer Networks_ by Tanenbaum. ________________________________________________ <>___, / / | ... and he called out and said, "Gabriel, give | /___/ __ / _ __ ' _ / | this man an understanding of the vision." | /\__/\(_/\/__)\/ (_/_(/_/|_ |_______________________________________Dan_8:16_|
