How does the CPU Cycle Execute Instructions Step by Step?
The CPU cycle runs in four steps: fetch, decode, execute, and store to speed up processing and improve computer performance.
- Fetch: The CPU fetches the instruction from main memory.
- Decode: The processor decodes the instruction to understand the task.
- Execute: The CPU executes the command using its processing power.
- Store: The result is stored in memory or sent for output.
