The type of memory used for temporary storage while a computer is running is RAM (Random Access Memory). RAM is volatile memory, which means it requires power to maintain the information stored within it. When the computer is on, RAM stores data that is actively being used or processed, allowing for quick access by the CPU. This makes it essential for running programs and executing tasks efficiently, as it enables fast read and write operations.

RAM is significantly faster than other types of storage, like hard drives and flash memory, which are used for long-term storage but are slower to access than RAM. On the other hand, ROM (Read-Only Memory) is non-volatile and is used to store firmware and system-level instructions that do not change during normal operation, making it unsuitable for temporary tasks. Thus, the role of RAM is crucial in a computer's performance during active processes, hence making it the appropriate choice for temporary storage.
