What is the purpose of 'parity checking' in data transmission or storage?
What is the purpose of 'parity checking' in data transmission or storage?
a)
To compress data to a smaller size.b)
To encrypt data for security.c)
To detect if a single bit error has occurred in a block of data.d)
To correct multiple bit errors.Explanation
Parity checking is a simple form of error detection. An extra 'parity bit' is added to a block of data, set to 1 or 0 to make the total number of '1' bits either even (even parity) or odd (odd parity). The receiving end checks the parity; if it's wrong, it knows an error occurred, but it cannot correct the error or detect an even number of bit flips.Related questions
