Which of the following is an error correction method using redundant bits.
The correct option is B Hamming code
Hamming code is an error
correction method using redundant bits.
Hamming code is a set of
error-correction codes that can be used to detect and correct the errors that
can occur when the data is moved or stored from the sender to the receiver. It
is technique developed by R.W. Hamming for error correction.
Hamming codes have a
minimum distance of 3, which means that the decoder can detect and correct a
single error, but it cannot distinguish a double bit error of some codeword
from a single bit error of a different codeword. Thus, they can detect
double-bit errors only if correction is not attempted.
An error-correcting code
(ECC) or forward error correction (FEC) code is a process of adding redundant
data, or parity data, to a message, such that it can be recovered by a receiver
even when a number of errors (up to the capability of the code being used) were
introduced, either during the process of transmission.
Error detection is the detection
of errors caused by noise or other impairments during transmission from the
transmitter to the receiver. Error correction is the detection of errors and
reconstruction of the original, error-free data.
