An external storage device
- B.
The computer's long-term memory
- C.
The computer's short-term memory
- D.
The memory that controls the computer.
Correct Answer
C. The computer's short-term memoryExplanation
RAM, or Random Access Memory, is a type of computer memory that is used to store data that is being actively used by the computer. It is considered the computer's short-term memory because it provides fast and temporary storage for data that the computer needs to access quickly. Unlike long-term storage devices such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off. Therefore, RAM is responsible for holding and providing quick access to data that is currently being processed by the computer.Rate this question:

Too many programs running concurrently can slow down the computer, or cause it to freeze.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When there are too many programs running at the same time on a computer, it can lead to a decrease in its performance. This is because the computer's resources such as CPU, memory, and disk space get divided among the running programs, causing them to compete for these resources. As a result, the computer may become slow and unresponsive, or even freeze completely. Therefore, the statement "Too many programs running concurrently can slow down the computer, or cause it to freeze" is true.Rate this question:

- A.
Only application software.
- B.
Only operating software.
- C.
Neither application software nor operating software.
- D.
Both application software and operating software.
Correct Answer
