Question 1: Name three main components of a CPU.

Answer: The Arithmetic Logic Unit (ALU), the Control Unit (CU), and the Cache.

Question 2: Describe the function of the Control Unit in the CPU.

Answer: The Control Unit directs all the operations inside the CPU by interpreting instructions and controlling the flow of data between components.

Question 3: What is the purpose of the Arithmetic Logic Unit (ALU)?

Answer: The ALU performs all arithmetic calculations and logical operations needed during processing.

Question 4: Explain what the Cache does in a CPU.

Answer: The Cache temporarily stores frequently used data and instructions to speed up processing.

Question 5: Complete the following truth table for an AND logic gate: | Input A | Input B | Output | |---------|---------|--------| | 0 | 0 | | | 0 | 1 | | | 1 | 0 | | | 1 | 1 | |

Answer: 0, 0, 0, 1

Question 6: Draw a simple diagram of how the Control Unit and the ALU connect within a CPU. Label each part clearly.

Answer: A diagram showing two boxes labeled 'Control Unit' and 'ALU' with lines indicating data flow between them and connecting to other parts like registers.

Question 7: Describe how the CPU uses the fetch-decode-execute cycle.

Answer: The CPU fetches instructions from memory, decodes what the instruction means, and then executes the command, repeating this cycle continually.

Question 8: Sketch a basic diagram of a CPU showing the ALU, Control Unit, and Cache. Leave space for labels.

Answer: A rough sketch with three main blocks arranged logically, with large blank areas for labels. The design should show the interconnection pathways between components.

Question 9: Identify which component in the CPU is primarily responsible for performing calculations.

Answer: The Arithmetic Logic Unit (ALU).

Question 10: Explain why the Cache is important for CPU performance.

Answer: Because it stores frequently accessed data close to the CPU, reducing the time needed to access data from main memory, thus speeding up processing.

Question 11: Describe one way that the Control Unit helps the CPU process instructions efficiently.

Answer: It interprets instructions and coordinates the activities of other parts of the CPU, ensuring that data moves correctly and tasks are performed in order.
