What is an Ethernet?
The Ethernet topology was developed at the University of Hawaii to connect computers on the many Islands. It was radio based design. Later, Robert Metacalfe went to Xeros's Palo Alto Research Center (PARC) laboratories and eliminated the radio portion and altered to co-axial cabling. Ethernet is one of the most popular LAN technologies in use today covering more than 85% of the networks. Ethernet system having of three basic elements:
4. The physical medium use to carry Ethernet signals among computers on the network
5. A set of rules (protocols) embedded in every Ethernet interface that will decide how multiple computers on the network will have access to the data on the medium.
6. An Ethernet frame that having of a standardized set of bits used to carry data over the system.
