In this article we will discuss Ethernet, will make brief discussion on Ethernet, last article we discuss about SONET.

Ethernet is a way of connecting computers together in a local area network or LAN. It has been the most widely used method of linking computers together in LANs since the 1990s. The basic idea of its design is that multiple computers have access to it and can send data at any time.


Ethernet is the traditional technology for connecting wired local area networks (LANs), enabling devices to communicate with each other via a protocol a set of rules or common network language.

Ethernet is a family of computer networking technologies commonly used in local area networks, metropolitan area networks and wide area networks. The connection among the devices could be wired or wireless. Ethernet, Token Ring and Wireless LAN using IEEE 802.11 are examples of standard LAN technologies.Ethernet is most widely used LAN Technology, which is defined under IEEE standards 802.3.

When using an Ethernet network, the network’s router also serves as a bridge to the Internet. The router connects to the modem, which carries the Internet signal, sending and receiving data packet requests and routing them to the proper computers on the network.
