Each Ethernet-equipped computer operates independently of all other stations on the network: there is no central controller. All stations attached to an Ethernet are connected to a shared signaling system... called the medium. To send data a station first listens to the channel, and when the channel is idle the station transmits its data in the form of an Ethernet frame, or packet.

As mentioned earlier, Ethernet cables are limited in their reach, and these distances (as short as 100 meters) are insufficient to cover medium-sized and large network installations. A repeater in Ethernet networking is a device that allows multiple cables to be joined and greater distances to be spanned. A bridge device can join an Ethernet to another network of a different type, such as a wireless network.

The Original Ethernet The first Ethernet (10Base5) used a bus topology and a thick coaxial cable. Transceivers connect the network adapters to the cable via a vampire tap that "bites" into the coax.

As Ethernet switch/routers continue to scale in terms of link speed and port density, device resiliency is becoming an indispensable system attribute.

An Ethernet device will detect a collision, while it is transmitting, only if the collision reaches it before it completes transmitting the entire frame. If the collision reaches the transmitter, after it completed sending the entire frame, then the transmitter will not detect the collision, it will assume the collision occurred because of some other frame. This is called "late collision". Late collision will occur, if the length of the Ethernet network segment is greater than the standard allowed length.
