Ethernet collisions can be classified mainly into two types: single collisions and multiple collisions. A single collision occurs when two devices try to transmit data simultaneously, resulting in a single point of failure. Multiple collisions happen when more than two devices attempt to send data at the same time, leading to a series of collisions. In both cases, the devices involved must use a backoff algorithm to retry transmission after a collision is detected.
Collisions
To prevent collisions.
Wired Ethernet can physically detect collisions, WIFI can't.
by comparinig the xmit line to the recieve line and look for differences
10-Mbps Ethernet, 100-Mbps or Fast Ethernet, and 1000-Mbps or Gigabit Ethernet.
Head-on collisions are usually the most fatal ones.
