Question: A _________ preamble is used to synchronize the receiver’s clock

Answer:

The synchronization preamble is typically more than one byte in size.

In network communications, synchronization preambles are usually several bytes long. The exact length can vary depending on the protocol or system being used. For example, Ethernet frames typically use a preamble of 8 bytes, while some wireless protocols may use longer preambles.

The synchronization preamble's purpose is to allow the receiver to synchronize its clock and bit timing with the incoming data stream. By transmitting a known pattern of bits at the beginning of a transmission, the receiver can adjust its clock and align its timing with the sender.

Therefore, a synchronization preamble is typically longer than a single byte to provide a sufficient sequence of bits for accurate clock synchronization.
