How does RAM differ from hard drive storage?

• A. RAM is non-volatile long-term storage
• B. RAM is slower than hard drive
• C. RAM is used to store the operating system only
• D. RAM is volatile, fast memory used for active tasks

Answer: (D)

RAM is fast, temporary memory that holds data the CPU is actively using. It is volatile, meaning its contents disappear when power is removed. This makes RAM ideal for active tasks because the processor can read and write data quickly while programs are running. In contrast, a hard drive (or SSD) stores data non-volatile for long-term storage and is much slower to read from or write to, so it isn’t used to keep active working data. When programs run, parts of the OS and program data are loaded into RAM for fast access, and if RAM gets full the system may move some data to disk via swap, which slows things down. Describing RAM as volatile, fast memory used for active tasks captures this essential difference.
