Which of the following best describes the role of RAM in a computer?

• A. It permanently stores all files
• B. It temporarily holds data for quick access
• C. It controls the CPU's operations
• D. It manages input and output devices

Answer: (B)

The role of RAM (Random Access Memory) in a computer is best described by the function of temporarily holding data for quick access. RAM serves as a volatile memory storage that allows a computer to store and retrieve data that is actively being used or processed by the CPU. When programs are running, they are loaded from permanent storage (like a hard drive or SSD) into RAM, where they can be accessed much more quickly by the processor. This rapid access is crucial for multitasking and efficiently executing applications, leading to improved performance. In contrast, permanent storage solutions, like hard drives or SSDs, are designed for long-term data retention but are slower to access compared to RAM. RAM's temporary nature means that all data stored in it is lost when the computer is powered off, highlighting the distinction between volatile and non-volatile memory.
