A minimum-size Ethernet frame carries 46 bytes of payload because

  • A.the payload must be a power of two in length
  • B.the frame must be long enough for collision detection to work
  • C.the checksum requires at least that many bytes before it can be computed
  • D.the addresses occupy the remainder of the minimum

Answer: B

The 64-byte minimum was set so that a station could still detect a collision before it finished transmitting on the longest legal shared segment. Shorter payloads are padded, which is why a very small message costs as much airtime as a moderate one.
