Answer: D

The cyclic redundancy check (CRC) can check for a block of
transmitted data. The workstations generate the CRC and
transmit it with the data. The receiving workstation
computes a CRC and compares it to the transmitted CRC. If
both of them are equal, then the block is assumed error
free. In this case (such as in parity error or echo check),
multiple errors can be detected. In general, CRC can detect
all single-bit and bubble-bit errors. Parity check also
(known as vertical redundancy check) involves adding a
bit-known as the parity bit-to each character during
transmission. In this case, where there is a presence of
bursts of errors (i.e., impulsing noise during high
transmission rates), it has a reliability of approximately
50 percent. In higher transmission rates, this limitation is
significant. Echo checks detect line errors by
retransmitting data back to the sending device for
comparison with the original transmission.
