Exam Compass - RAM Quiz Flashcards

1
Q

Random Access Memory (RAM) falls into the category of the so-called volatile storage media. It requires a continuous flow of electricity to preserve its contents thus all the data stored in RAM lasts only while the power is on.

Q

Certain types of RAM take advantage of an additional bit in order to detect whether a data error has occurred. This extra bit is used to store information about the count of bits set to the value of 1 in a given string of data (typically one byte). Examining the value of the additional bit at different stages of processing allows to detect whether the data has been corrupted or not. What is the name of that extra bit?
Digest
Archive bit
Hash value
Parity bit

A

Parity bit
