The receiver can do the identical sums with the data it sees, examine the parity bit, and so detect if a mistake has been made. Unfortunately, with easy parity checking, it isn’t potential to say the place an error has been made or to appropriate it on the spot, but the receiver can no less than spot a batch of incorrect data and ask for it to be despatched once more.
