How does parity checking work, and what are its limitations in terms of error detection and correction?

		The parity bit ensures the total number of 1 bits is always odd (or even), allowing detection but not correction of single-bit errors.
		Parity checking can both detect and correct any number of bit errors in the message.
		Parity checking has no ability to detect or correct any errors in the message.
		Parity checking can detect and correct all burst errors in the message.
