Computer Science for IGCSE & O level - Data Transmission (Section 7 - No. 49)
What is the main disadvantage of using parity checks for error detection?
It can only detect single-bit errors.
It requires significant processing power.
It increases the transmission speed.
It can detect all types of errors.
Vysvětlení
Parity checks are simple but only effective at detecting single-bit errors. They may miss more complex errors.
