Answer Posted / Manish Singh
Error Detection and Correction Techniques are used to ensure data integrity during transmission. Three common methods are Parity Check, Cyclic Redundancy Check (CRC), and Checksum. Parity Check adds an extra bit to each byte to indicate the parity (even or odd). CRC calculates a polynomial value based on the data and appends it to the data. Checksum calculates the sum of all bytes in the packet and subtracts this from a large number to fit within one byte.
