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

To store permanent data
To execute application software
To store temporary data (correct)
To provide a place for firmware

Which type of RAM is typically more expensive due to its ability to hold power longer than DRAM?

Read-only memory (ROM)
Static RAM (SRAM) (correct)

Internal Memory

Memory that stores data quickly while the computer is running.

RAM (Random Access Memory)

The primary internal memory used by the CPU to store temporary data for active applications.

DRAM (Dynamic RAM)

A type of RAM that needs constant refreshing and is affordable.

SRAM (Static RAM)

A type of RAM that holds data as long as the power is on and is faster but more expensive than DRAM.
