Question 13

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

Answer 13

Parity Bit

Question 14

ECC type RAM:

Can only detect errors, but does not have the capability to correct them
Refers to parity RAM (the two terms are interchangeable)
Offers better performance in terms of speed when compared to a non-ECC type of RAM
Can detect and correct errors

Answer 14

Can detect and correct errors

Question 15

Compared to non-ECC memory, ECC RAM is a less expensive option and will always perform faster.

True
False

Answer 15

False
