Final answer:
A single parity bit can be used for error detection and single error correction in data transmission.
Step-by-step explanation:
A single parity bit can be used for detection and single error correction.
When a parity bit is added to a set of data bits, it serves as a way to detect errors in the transmission of the data. The parity bit is calculated based on the number of 1s in the data. If the number of 1s is odd, the parity bit is set to 1, making the total number of 1s even. If the number of 1s is even, the parity bit is set to 0, making the total number of 1s odd. Upon receiving the data, the recipient can check the parity bit to determine if any errors occurred during transmission.
In addition to error detection, a single parity bit can also be used for single error correction. If an error is detected, the recipient can use the parity bit to determine which bit in the data was flipped and correct the error. However, a single parity bit can only correct one error. If multiple errors occur, the system may not be able to accurately correct them.
