Ethernet
One of the most commonly used LAN technology is Ethernet which was established by DIX (DEC, Intel, and Xerox corporations). It is a registered trademark name with Xerox Corporation and standardized in the IEEE 802.3 group of the Institute of Electrical and Electronics Engineers (IEEE). Ethernet uses twisted-pair cable as well as fiber optic cable. CSMA/CD is used as a contention-based protocol for the working of Ethernet. A contention-based protocol is the protocol that is used for wireless communication tool that permits more than one user to use similar radio frequency without per-coordination. Ethernet requires a repeater (an interconnecting device that is added to a network to extend the signal on the cable) to function. A block of data that is transmitted to Ethernet is known as Ethernet Frame. The data transmission rate of Ethernet is identified in bits per second. An Ethernet can be broadly classified into three categories based on the speed of data transfer: Standard Ethernet, Fast Ethernet, and Gigabit
