Which term best describes memory that is fast and directly accessible by the CPU for active tasks?

• A. Cache
• B. Primary storage
• C. Secondary storage
• D. Cloud storage

Answer: (B)

In a computer, memory that the CPU can quickly access while it runs programs is called primary storage. It’s fast enough to keep up with the CPU and is directly connected to it, allowing the CPU to fetch instructions and data without long delays. Cache memory is even faster and sits very close to the CPU, but it’s a small, specialized part of the memory system aimed at speeding up repeated accesses. The question’s focus is on the general fast, directly accessible memory used for active tasks, which is primary storage. Secondary storage and cloud storage are slower and not directly accessible to the CPU during active execution, so they aren’t the right fit.
