"The situation that occurs when two or more devices attempt to send a signal along the same channel at the same time. The result of a collision is generally a garbled message. All computer networks require some sort of mechanism to either prevent collisions altogether or to recover from collisions when they do occur.."
"The result of two computers on a network attempting to send information or access a network resource at the same time. When this happens, both signals are destroyed and must be retransmitted. Most networks have some kind of built-in collision detection to avoid this problem."
