I would like to ask this question from Serial Port Communication in chapter 8051 Microcontroller of Microcontroller

Answer 1

Correct answer is (b) it tells us about the start and stops of the data to be transmitted or received

The explanation is: In data framing in asynchronous means of communication, the data is packed between the start and the stop bit. This is done so as to tell the other computer about the start and the end of the data.
