What is the primary function of RAM in a computer?

The primary function of RAM (Random Access Memory) in a computer is to provide space for running applications temporarily. This type of memory is designed for quick access and allows the CPU to retrieve and execute programs and data that are currently in use. Because RAM is volatile memory, it loses its contents when the computer is powered off, which is why it is used for temporary storage rather than permanent data retention.

When applications are running, they require a certain amount of memory to function efficiently, and RAM supplies that space, facilitating smooth operation and quicker access to data compared to permanent storage options like hard drives or SSDs. This is essential for multitasking and for applications to perform effectively without significant delays.

The other options highlight different aspects of computer functionality. For instance, permanent data storage is managed by hard drives or SSDs, power supply management is handled by the power supply unit, and graphics performance is often enhanced by dedicated GPUs rather than RAM itself, making them less relevant in defining the core purpose of RAM.
