Question

Start and stop bits are used in serial communication for

• A. error detection
• B. error correction
• C. synchronization
• D. slowing down the communication

Answer 1

The correct option is C synchronization

Start and stop bits are used in serial communication for synchronization.

The start and stop bits are used in asynchronous communication as a means of timing or synchronizing the data characters being transmitted.

The start bit is used to signal the beginning of a frame. The stop bit is used to signal the end of a frame. The data is contained in the data bits and the parity bit is an extra bit that is often used to detect transmission errors.

Synchronous serial communicationdescribes a serial communication protocol in which "data is sent in a continuous stream at constant rate”.
