Understanding Padding in Serial Data Transmission
In serial data transmission, the padding of data bytes is a crucial process that aids in accurate data reception. The choice of padding with a leading 0 and trailing 1s primarily addresses the issue of signal integrity during transmission.
Receiver's Ability to Recover Lost Bits
- Padding is vital because during data transmission, especially in serial communication, certain bits may be lost due to noise or signal degradation.
- The addition of padding bits (0 at the start and 1s at the end) serves as a reference for the receiver. When the receiver detects a sequence of bits, it uses these padding bits to identify the start and end of each byte.
- If a '0' is lost during transmission, the receiver can still recognize the byte's beginning through the leading '0' and can detect the end through the trailing '1s'. This mechanism helps in reconstructing the original data byte accurately.
Why Not Other Options?
- While synchronization (option a) is important, it is not the primary reason for padding. Instead, synchronization mechanisms often rely on specific timing signals.
- Parity computation (option c) is a method for error detection but does not explain the necessity of padding with specific bits in the context given.
- Thus, the correct answer is option 'B' as the padding bits provide essential signals that assist the receiver in recovering any lost bits during transmission.
In summary, the padding in serial data transmission helps ensure that the receiver can accurately interpret the data, even in the presence of potential transmission errors.
