What is the primary function of RAM in a computer system?

To manage the computer's power consumption
To handle the operating system's background processes
To temporarily store data and instructions for rapid access by the CPU (correct)
To provide long-term storage for data and programs

Why is RAM considered a type of volatile memory?

Because it can only be accessed in a specific order
Because it can only be used for temporary storage
Because it has a limited capacity for data storage
Because it requires a constant power supply to retain data (correct)

How is the speed of RAM measured?

In gigabytes (GB)
In teraflops (TFLOPS)
In megabits per second (Mbps)
In megahertz (MHz) (correct)
