(Latin) an error.
error detection
In computing, the techniques whereby a
program can detect incorrect data. A common
method is to add a check digit to important
codes, such as account numbers and product
codes. The digit is chosen so that the code
conforms to a rule that the program can
verify. Another technique involves
calculating the sum (called the hash total)
of each instance of a particular item of data
and storing it at the end of the data.
