Preamble
CRC

A

Preamble

Explanation:
Preamble, a 7-byte series of alternating ones and zeroes followed by a 1-byte start frame delimiter or an 8-byte series of alternating ones and zeroes, always precedes a frame. The preamble gives a receiving NIC time to realize a frame is coming and to know exactly where the frame starts. The preamble is added by the sending NIC
