2.2 Methods of Error Detection (Parity & ARQ)
Error Checking and Automatic Retransmission During data transmission, electrical noise and interference can invert or corrupt bits. Systems use error detection protocols to detect and correct corruption. Parity Checks: Odd or Even parity. A parity bit is added to make the total number of 1s odd or even. Parity blocks / parity bytes allow pinpointing […]
