In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.

the correction which is made to get correct measurement after zero error

Error-correcting code for long burst errors is so complex that it is a inefficient means of error correction...
