What is the role of Random-access memory (RAM) in a computer system?

Random-access memory (RAM) plays a crucial role in a computer system by keeping data immediately accessible for the CPU. This is essential because RAM is a type of volatile memory that allows the CPU to retrieve and store data quickly during processing. When applications are running, they load data and instructions into RAM so that the CPU can access this information without delay, improving overall system performance and efficiency.

The characteristics of RAM allow for rapid read and write access, which is vital for tasks that require immediate data handling, such as multitasking or running complex applications. When the computer is powered off, the data in RAM is erased, which is why it is not used for permanent data storage, distinguishing it from other storage forms like hard drives or SSDs.

In contrast, other options do not accurately describe the function of RAM. For example, RAM does not provide permanent storage for applications; that is the role of hard drives or solid-state drives. Additionally, while input device information may be processed by the CPU, it is not specifically stored in RAM for that purpose. Lastly, regulating the power supply to components is handled by the power supply unit and not RAM. Thus, the correct answer reflects RAM's integral function in providing immediate data access to the CPU, facilitating efficient
