2‚ 2012 Ethernet is a family of computer networking technologies for local area networks (LANs). Ethernet was introduced to the commercial marketplace in 1980‚ and has replaced other LAN technologies. It’s a baseband LAN specification invented by Xerox Corporation that operates at 10Mbps using carrier sense multiple access collision detection (CSMA/CD) to run over coaxial cable. Ethernet was designed to serve in networks with sporadic‚ occasionally heavy traffic requirements‚ and the IEEE 802

commercial release‚ Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. Ethernet is a family of computer networking technologies for local area networks‚ known as LANs. Ethernet was commercially introduced in 1980 and standardized in 1985. Ethernet has largely replaced competing wired LAN technologies such as a token. The Ethernet standards comprise several wiring and signalling variants of

layer and is concerned with sharing the physical connection to the network among several computers. Each computer has its own unique MAC address. Ethernet is an example of a protocol that works at the Media Access Control layer level. There are two basic media access control methods for shared media: 1. Controlled access method. 2. Contention based access method. Controlled accessed method: When using the controlled access method‚ network devices take turns‚ in sequence‚ to access the medium. This method

Protocols for computer networking all generally use packet switching techniques to send and receive messages in the form of packets. 2. Define the role of an intermediary device in the network. Communication to run smoothly across the network there are devices that place intermediary roles in networking. These
