In asynchronous serial communication the physical layer provides ___________

In asynchronous serial communication the physical layer provides ___________ Correct Answer both start & stop signalling and flow control

In asynchronous serial communication, the communication is not synchronized by clock signal. Instead of a start and stop signaling and flow control method is followed. Unlike asynchronous serial communication, in synchronous serial communication a clock signal is used for communication, so the start and stop method is not really required.
