Ethernet is the most popular LAN technology in use.It provides a framework for data transmission.A standard Ethernet network can transmit data at a rate of up to 10 Megabits per second (10 Mbps). Ethernet is popular because it gives a good balance between speed, cost, and ease of installation. The Institute for Electrical and Electronic Engineers developed an Ethernet standard known as IEEE Standard 802.3. This standard defines rules for configuring an Ethernet network and also specifies how the elements in an Ethernet network interact with one another.
