Quizplus · Accepted Answer

The preamble is a sequence of alternating 0s and 1s used by the receiver to establish bit synchronization. It is used to aid the receiver in detecting the start of a frame and as a reference for bit timing. The source and destination addresses are used to identify the sender and receiver of the data, while the start frame delimiter marks the beginning of a frame after the preamble.
