Installed in the computer, Random Access Memory (RAM) is classified as:

Random Access Memory (RAM) is classified as temporary memory because it is designed to store data and instructions that the computer needs while it is operating. This type of memory is volatile, meaning that its contents are lost when the computer is turned off or restarted. RAM allows for quick access and manipulation of data, which is essential for running applications and processing tasks efficiently.

In contrast, permanent memory refers to storage solutions that retain data even when the power is off, such as hard drives and solid-state drives. External memory typically refers to storage devices that can be connected to a computer via USB or other ports and also retain data permanently, while internal storage typically pertains to the main storage of a computer, including both RAM and permanent memory. However, RAM specifically acts as a temporary workspace for the CPU, emphasizing its role in a computer's performance during active tasks.
