In this transmission , each data word is accompanied by stop(1) and start (0) bits that identify the beginning and ending of the word. When no information is being transmitted (sender device is idle), the communication line is usually high (in binary 1), i.e., there is a continuous stream of 1.
Advantage: Reliable as the start and stop bits ensure that the sender and receiver remain in step with one another.
Disadvantage: Inefficient as the extra start and stop bits slow down the data transmission when there is a huge volume of information to be transmitted.
