Final answer:
A packet must be resent due to an interruption before the 64th byte is transmitted is known as a late collision. Late collisions are abnormal and indicative of network issues.
Step-by-step explanation:
When a packet must be resent because of an interruption that occurs before the 64th byte has been transmitted, it is known as a late collision. In Ethernet networking, collisions are expected in a shared medium, but they should typically occur early within the first 64 bytes of the frame. If a collision occurs after the 64th byte, this is abnormal and usually indicates a problem, such as a network segment that is too long or a malfunctioning repeater. The term 'runt' refers to a packet that is smaller than the minimum allowed size, while 'jumbo frame' and 'baby giant' refer to frames that are larger than the standard permitted size.
