What is the function of RAM in a computer?

The function of RAM, or Random Access Memory, in a computer is to temporarily hold data and programs currently in use. This allows for quick access and processing by the CPU, enabling the computer to operate efficiently and effectively while running applications. When you open a program or file, it is loaded from the computer's storage (like a hard drive or SSD) into RAM, which provides faster read and write access compared to other storage types.

This temporary storage is crucial because when the computer is powered off or restarted, the data stored in RAM is lost, emphasizing its role in the short-term operation of the system. The other options pertain to different functions: permanent data storage is managed by hard drives or SSDs, graphic data processing is typically executed by the GPU, and peripheral device connection involves ports and interfaces rather than RAM. Thus, the correct answer accurately reflects the transient nature and purpose of RAM in computer functioning.
