Computer Science for IGCSE & O level - Data Transmission (Section 6 - No. 28)
What is the main limitation of using parity checks for error detection?
It can only detect single-bit errors.
It cannot detect any errors.
It requires extra bits for each byte.
It slows down data transmission.
Објашњење
Parity checks are simple but primarily detect single-bit errors. They can miss errors if two bits are corrupted.
