Explanation:
Detailed explanation-1: -To recap, Ethernet has a minimum frame size of 64 bytes, comprising an 18-byte header and a payload of 46 bytes. It also has a maximum frame size of 1518 bytes, in which case the payload is 1500 bytes. If the message to be sent leads to a frame size of less than the 64-byte minimum, the additional bytes are padded.
Detailed explanation-2: -Thats because there is a minimum length enforced on the frames payload to allow collision detection to work reliably. – Alex K. Minimum frame size is 64 bytes (not bits) including CRC.
Detailed explanation-3: -Runts are the number of packets that are smaller than the minimum size of less than 64 bytes.
