Both of the above
C. Both of the above
1. Parity Bit: A parity bit is a simple error detection mechanism that adds an additional bit to a string of binary code. Its value is set to either 1 or 0 to ensure that the total number of 1-bits in the string is even (even parity) or odd (odd parity). This can help detect any single-bit errors that may occur during the data transmission or storage.
2. Checksum: A checksum is a value calculated from a data set to detect errors in data transmission or storage. It’s typically used in digital networks and storage devices. The sender calculates the checksum value based on the data it intends to transmit, and the receiver calculates the checksum again from the received data. If the two values match, it’s likely that the data hasn’t been altered; discrepancies can indicate errors.
3. Cyclic Redundancy Check (CRC): CRC is a technique used to detect accidental changes to raw data in digital networks and storage devices. It involves polynomial division of the data’s binary representation and produces a check value that is appended to the data. When the data is examined, a new CRC is calculated and compared to the original one. If they do not match, it suggests an error in the data.
4. Hamming Code: The Hamming code is an error-detecting and error-correcting code that is designed to detect up to two simultaneous bit errors and correct single-bit errors without detection of uncorrected errors. It’s particularly useful
