Which memory is used to increase the processing speed of a computer?
Correct answer: C. Cache memory
- A. RAM (Random Access Memory)
- B. ROM (Read-Only Memory)
- C. Cache memory
- D. Hard disk
Explanation
Cache memory is a small amount of very high-speed memory that sits between the CPU and RAM. It stores frequently accessed data and instructions from RAM, allowing the CPU to access them much faster than if it had to retrieve them from RAM every time. This significantly improves processing speed.In essence, cache memory acts as a buffer between the CPU and RAM, providing faster access to frequently used data and instructions.
