How does RAM differ from storage drives in terms of speed, volatility, and purpose?

• A. RAM is non-volatile and slower, mainly for long-term data; storage is fast and volatile and used for running programs.
• B. RAM is fast, volatile memory used for active data and programs; storage drives are non-volatile persistent storage used for long-term data retention.
• C. RAM stores data permanently; storage drives lose contents when power is off.
• D. RAM is slower than storage and used for archiving files.

Answer: (B)

RAM is designed to be extremely fast so the CPU can quickly access data and instructions for programs that are currently running. It’s volatile, which means it loses its contents when the power is off, so it’s not used for long-term storage. Storage drives, like hard drives and solid-state drives, hold data even without power, making them non-volatile and suitable for long-term retention. They are slower than RAM, but they provide much larger, persistent storage for the operating system, applications, and files. So describing RAM as fast, volatile memory for active data and programs, with storage drives as non-volatile persistent storage for long-term data, accurately captures the real differences.
