Q

Certain types of RAM use an additional bit in order to detect whether a data error has occurred. This extra bit is used to store information about how many bits are set to a value of 1 in a given string of data (typically one byte). Examining the value of this additional bit at different stages of processing allows to detect whether the data has been corrupted. What is the name of this extra bit?

Hash value
Digest
Archive bit
Parity bit

A

Party bit
