The correct answer is D: Some types of errors can be detected. The advantage of including parity bits in ASCII characters is that some types of errors can be detected. Parity bits allow the receiver to detect when an odd number of bits have been corrupted. Parity bits add an extra bit to each character to make the total number of 1-bits either even (even parity) or odd (odd parity). If a single bit error occurs (or any odd number of bit errors), the parity check will fail, indicating an error. However, parity can only detect errors - it cannot correct them. Also, if an even number of bits are corrupted, the parity check will pass incorrectly. Despite these limitations, parity is a simple and effective way to detect many transmission errors.
