About this calculator
Overview
Parity bits detect single-bit errors in data transmission. Even parity: total 1s is even; Odd parity: total 1s is odd. Simple error detection used in RAM, serial communication.
💡
Pro Tips
Even parity most common.
Cannot detect 2-bit errors.
Used with other error detection methods.
Serial communication: 7/8 data + parity.

Fun Facts
"Parity bit adds 1 bit overhead per byte."
"RAM uses ECC parity for error correction."
"ASCII originally 7-bit + parity."
"Cannot correct errors, only detect."
Formula: Even: parity = 1 if odd 1s; Odd: parity = 1 if even 1s
