Which term describes non-information bits that help manage framing and synchronization?

• A. Overhead Bits
• B. Information Bits
• C. Control Bits
• D. Synchronization Bits

Answer: (A)

In digital transmission, payload is the user data, while the rest of the bits are overhead. Overhead bits exist to support the structure and timing of the transmission: they mark frame boundaries, carry headers and trailers, and help the receiver stay synchronized with the sender’s clock. Preambles, frame delimiters, and related control fields are all overhead that enables framing and synchronization without carrying actual user information. While synchronization bits and control bits are specific kinds of overhead, the broad term that describes all non-information bits used to manage framing and timing is overhead bits.
