How an Ethernet Worked?
The operation of Ethernet can be explained in simple terms as follows:
Each computer on the Ethernet Network, also called as a node, operates independently of all other nodes. All nodes attached to an Ethernet are linked to a shared medium over which the Ethernet signals travel serially, one data bit at a time.
To send data a station first listens to the channel and when the channel is idle the station transmits its information in the form of an Ethernet frame, or packet. The Ethernet rules (protocol) are explained in such a way that each node gets a fair amount of frame transmission opportunity.
