True or False. When the computer is turned off, the contents of RAM are saved.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When the computer is turned off, the contents of RAM are not saved. RAM (Random Access Memory) is a type of volatile memory, which means that it requires a constant flow of electricity to retain data. When the power is cut off, the data stored in RAM is lost. This is why it is important to save any important data to a non-volatile storage device, such as a hard drive, before turning off the computer.Rate this question:

True or False. Because a hard drive produces so much heat, a heat sink is used to dissipate the heat so that the internal components don't melt.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A hard drive does not produce a significant amount of heat that would require a heat sink to dissipate it. While hard drives do generate some heat during operation, it is not enough to cause the internal components to melt. Heat sinks are commonly used in devices like CPUs and GPUs that generate a higher amount of heat. Therefore, the statement that a heat sink is used for a hard drive to prevent internal components from melting is false.Rate this question:

True or False. The BIOS draws cool air over heat critical components inside the PC case.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The BIOS (Basic Input/Output System) is a firmware that is responsible for initializing and controlling hardware components during the boot process. It is not directly involved in drawing cool air over heat critical components inside the PC case. The task of cooling components is typically performed by fans and cooling systems, which are separate from the BIOS. Therefore, the statement that the BIOS draws cool air over heat critical components is false.Rate this question:
