Which statement about RAM is true?

• A. RAM stores data permanently
• B. RAM is volatile and loses data when power is removed
• C. RAM cannot be overwritten
• D. RAM is slower than the CPU

Answer: (B)

RAM is volatile memory, meaning it only holds data while power is supplied. It’s the computer’s fast working space for current programs and data, so the CPU can access what it needs quickly. Because it’s designed to be easily read from and written to, RAM can be overwritten continually during operation. When you turn off the power, the contents disappear, which is why you save important work to non-volatile storage like a hard drive or SSD. The other statements conflict with how RAM works: it isn’t permanent storage, it isn’t unchangeable, and while RAM is fast, comparing it directly to the CPU doesn’t reflect how memory and processing interact across caches and buses.
