Controls designed to minimize the risk of data transmission errors include all of the following except Parity checking is a data transmission control in which the receiving device recalculates the parity bit to verify accuracy of transmitted data. Paritychain provides a way to ensure that validated transactions and documents are not altered. Transmission Control Protocol (TCP) assigns a sequence number to each packet and uses that information to verify that all packets have been received and to reassemble them in the correct order. Checksum which is a data transmission control that uses a hash of a file to verify accuracy.
