Calculate parity bits for error detection in data transmission
About Parity Bits
Parity bits are used for error detection in data transmission. They ensure that the number of 1s in a data word (including the parity bit) is either even (even parity) or odd (odd parity). This helps detect single-bit errors during transmission.
Parity Bit Tips
- Even Parity: Total number of 1s (including parity bit) must be even
- Odd Parity: Total number of 1s (including parity bit) must be odd
- Error Detection: Can detect single-bit errors and odd numbers of bit errors
- Limitations: Cannot detect even numbers of bit errors
- Applications: Memory systems, serial communication, RAID arrays
- Calculation: Count 1s in data, add parity bit to achieve desired parity
