Answer / guest
Answer: D
A parity check will help to detect data errors when data are
read from memory or communicated from one computer to
another. A one-bit digit (either 0 or 1) is added to a data
item to indicate whether the sum of that data item's bit is
odd or even. When the parity bit disagrees with the sum of
the other bits, an error report is generated. Choices A, B
and C are types of data validation and editing controls.
