Discuss the role of parity bits in error detection.
Parity bits are only used in text-based communication.
Parity bits ensure the data is compressed before sending.
Parity bits are used to encrypt data during transmission.
Parity bits are used to detect errors by ensuring the total number of ones in a binary code is either even or odd, allowing for error detection during transmission.
