Which of the answers listed below refers to a source of power for an RTC when the computer is turned off?

What is the name of the most common connector type used for providing power to various hardware components inside the computer case?

A switch, button, or LED on the front/top panel of a computer case has a connector linked to it that must be attached to the appropriate pins on the:

Which of the memory types listed below are designed to store permanent data that cannot be changed? (Select all that apply)

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.

Which of the answers listed below refers to the number of pins used by MicroDIMM DDR SDRAM memory modules?

What is the number of contact pins used by MicroDIMM DDR2 SDRAM modules?

ECC type RAM:

Certain types of RAM take advantage of an additional bit in order to detect whether a data error has occurred. An extra bit is used to store information about the number of bits set to the value of one in a given string of data (typically one byte) and by examining that information at different stages of processing it is possible to detect whether the data has been corrupted or not. What is the name of that extra bit?

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

The color-coded memory slots on the motherboard indicate that the system is capable of taking advantage of the multi-channel memory architecture.
