What is “late collision”?
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.
