Q63 / 100
What is the purpose of a "parity bit" in digital data transmission?
Correct! Well done.
Incorrect.
The correct answer is A) An extra bit added to a group of bits to make the total number of 1s either even (even parity) or odd (odd parity), allowing the receiver to detect certain single-bit transmission errors
A
Correct Answer
An extra bit added to a group of bits to make the total number of 1s either even (even parity) or odd (odd parity), allowing the receiver to detect certain single-bit transmission errors
Explanation
Parity checking is a simple error-detection scheme: if the received data's parity doesn't match the expected value, a single-bit error is detected (though it cannot identify which bit, and can't detect even numbers of bit errors).
