What type of memory is typically used for primary storage in a computer?

Random Access Memory (RAM) is the correct answer because it serves as the main type of volatile memory used for primary storage in computers. RAM provides temporary storage for data that the CPU is currently processing, enabling fast access and efficient performance while applications are running. It allows the system to read from and write to memory quickly, which is essential for the overall speed and functionality of the computer.

When the computer is powered off, the data stored in RAM is lost, distinguishing it from non-volatile storage methods. In contrast to flash memory, which is typically used for secondary storage and retains data even when power is off, RAM is designed specifically for speed and volatility to support active processes. Similarly, Read-Only Memory (ROM) serves a different purpose, as it stores firmware and other permanent data needed to boot the system but does not provide workspace for running applications. External hard drives serve as additional storage solutions but do not operate as primary memory for immediate data access. Thus, RAM is a crucial component that directly impacts a computer's performance during active tasks.
