Q

TRUE/False

A motherboard with color coded memory slots provides support for multi channel memory architecture.

A

True

19
Q

What is required to take advantage of the performance benefits offered by the multi channel memory architecture?

A

Installing memory modules of matching types/speed/capacity

installing modules in appropriate slots

20
Q

What can ECC RAM do?

A

Can detect and correct errors.

21
Q

Certain types of RAM use an additional bit in order to detect whether a data error has occured. This extra bit is used to store information about how many bits are set to a value of 1 in a given string.
Examining this extra but allows to detect whether data is corrupted or not. What is the name of this extra bit?

A

Parity bit

22
Q

Which of the following are characteristics of the type of RAM most commonly used as the main system memory in desktop PCs?

A

Non ECC (error correcting) memory

Dynamic RAM
