Question 1: List three main components of a CPU and briefly describe their functions.

Answer: The three main components are: the ALU (Arithmetic Logic Unit) which performs calculations and logical operations; the Control Unit which manages data flow and instructs other parts of the CPU; and registers which temporarily store data for quick access.

Question 2: Explain the purpose of the Cache within a CPU.

Answer: Cache stores frequently accessed data and instructions close to the CPU, allowing faster access and improving overall processing speed.

Question 3: Describe the difference between the Control Unit and the ALU in a CPU.

Answer: The Control Unit directs the operation of the CPU by interpreting instructions and controlling data movement, while the ALU performs arithmetic calculations and logical operations.

Question 4: Identify which part of the CPU handles logical operations and calculations.

Answer: The Arithmetic Logic Unit (ALU).

Question 5: Draw a simple block diagram that shows the main components of a CPU: the Control Unit, the ALU, and Registers. Label each component.

Answer: A diagram with three labeled blocks: one labeled 'Control Unit', one labeled 'ALU', and one labeled 'Registers', connected appropriately to show data flow.

Question 6: Complete the truth table for an AND logic gate with two inputs, A and B.

Answer: Input A: 0, Input B: 0, Output: 0; Input A: 0, Input B: 1, Output: 0; Input A: 1, Input B: 0, Output: 0; Input A: 1, Input B: 1, Output: 1.

Question 7: Complete the truth table for an OR logic gate with two inputs, A and B.

Answer: Input A: 0, Input B: 0, Output: 0; Input A: 0, Input B: 1, Output: 1; Input A: 1, Input B: 0, Output: 1; Input A: 1, Input B: 1, Output: 1.

Question 8: Draw a logic circuit for an AND gate and label the inputs and the output.

Answer: A correct sketch would show a standard AND gate shape with two inputs entering on the left side and one output exiting on the right, all labeled appropriately.

Question 9: Sketch a logic circuit that combines an AND gate and an OR gate to produce a specific output: the output should be true if either A and B are both true, or if C is true.

Answer: A correct sketch would show A and B entering an AND gate, C entering an OR gate along with the output of the AND gate, with the final output labeled.

Question 10: Explain why the CPU's clock speed is important for overall performance.

Answer: The clock speed determines how many cycles the CPU can perform per second; higher speeds generally mean faster processing and better performance.

Question 11: Describe what a 'multi-core' CPU is and how it improves performance.

Answer: A multi-core CPU has multiple processing cores within a single chip, allowing it to perform multiple tasks simultaneously, which improves multitasking and processing speed.
