Answer: C
In asynchronous serial communication, the transmitter and receiver do not share a common clock signal. To ensure reliable data transfer, they must be synchronized at the start of each transmitted character.
- Start Bit: Signals the receiver that a new data frame is beginning. This transition (typically from high to low voltage) allows the receiver to synchronize its internal clock with the incoming data stream.
- Stop Bit: Signals the end of the data frame and returns the transmission line to the idle state (typically high voltage), preparing it for the next start bit.
Therefore, start and stop bits are primarily used for synchronization between the sender and the receiver.
