The CPU- What you need to know
- State the purpose of the CPU Describe the function of the CPU as fetching and executing instructions stored in the memoryExplain how common characteristics of CPUs such as clock speed, cache size and number of cores affect their performance.
Types

- Fetches data
- Decodes data
- Execute instructions
- Brain of the computer
- The purpose of the CPU is to process data
- Fetch- Decode- Execute cycle
Information
- Description
- Use this mind map as a starting point. Add at least one branch to each point to explain either what this means or why this is important for the CPU and its performance.
