Explain the relationship between a CPU, programs, instructions, and cache memory.
Understand the Problem
The provided text describes the central processing unit (CPU) and its role in a computer system. It explains the relationship between the CPU, programs, instructions, and cache memory.
Answer
The CPU executes program instructions, with remaining instructions stored in cache memory for quick access.
The CPU executes instructions from programs. These instructions are stored in a specific order. While the CPU is executing one step, the other instructions are stored in cache memory for quick access.
Answer for screen readers
The CPU executes instructions from programs. These instructions are stored in a specific order. While the CPU is executing one step, the other instructions are stored in cache memory for quick access.
More Information
The CPU fetches instructions from memory to execute programs. Cache memory is a high-speed storage area that stores frequently accessed data and instructions, allowing for faster retrieval than accessing main memory (RAM) directly.
Tips
It's easy to confuse the roles of RAM and cache memory. Remember that cache is a smaller, faster memory closer to the CPU, used for frequently accessed data, while RAM is the main system memory.
