GATE | GATE-CS-2002 | Question 11

In serial data transmission, every byte of data is padded with a ‘0’ in the beginning and one or two ‘I’ s at the end of byte because
(A) Receiver is to be synchronized for byte reception
(B) Receiver recovers lost ‘0’ and ‘1’s from these padded bits
(C) Padded bits are useful in parity computation
(D) None of these


Answer: (A)

Explanation: In serial communication, the sender & receiver needs to be synchronized with each other.

‘0’ is added in the beginning of data as start bit and ‘1’ is added at the end as a stop bit.
The start signal tells the receiver about the arrival of data and the stop signal resets the receiver’s state for the arrival of a new data.

 
Thus, in serial communication receiver is to be synchronized for byte reception.
