Fragment Collision
Today one of my friends ask a question about Fragment Collision (short/runt frames) so i'm going to write brief of it in this section.
As you know a collision occurs when two stations begin transmission simultaneously when they detect silence on the network so at that time they stop transmission and send a JAM signal and back off for a while (Random amount of time)
The mechanism requires that stations be close enough together for each station to see any possible attempted transmisstion before the first 64 bytes of its frame have been transmitted.(This is because 64 bytes is the minimum frame size for an Ethernet network).
The IEEE specification defines the term fragment collision for that .
the below picture is a frame as Fragment collision .
