Difference between Visual check and Parity check

Visual check

This is checking for errors by comparing entered data with original document (NOTE: this is not the same as proof reading!!).

Parity check

It is used to check data following potential transmission errors; an additional bit is added to each binary number before transmission - for example EVEN parity makes sure every number has an even number of 1 - bits;

Example: if 11000110 is sent (four 1's) and 11100110 is received (five 1's) then the system will know an error has occurred.
