Question 1: Name two main components of a Central Processing Unit (CPU).

Answer: Two main components are the Arithmetic Logic Unit (ALU) and the Control Unit (CU).

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

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

Question 3: Complete the truth table for an AND gate with inputs A and B, and output C.

Answer: | A | B | C | |---|---|---| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |

Question 4: Complete the truth table for an OR gate with inputs A and B, and output C.

Answer: | A | B | C | |---|---|---| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

Question 5: Draw a logic circuit for an AND gate and label each part clearly.

Answer: A correct sketch would show two input lines converging into a shape labeled 'AND' with an output line coming from the shape.

Question 6: Draw a logic circuit for an OR gate and label each part clearly.

Answer: A correct sketch would show two input lines entering a shape labeled 'OR' with an output line leaving the shape.

Question 7: Explain how the ALU contributes to the CPU's function.

Answer: The ALU performs calculations and logical operations, enabling the CPU to process data and execute instructions.

Question 8: What is the primary purpose of the CPU's registers?

Answer: Registers temporarily store data and instructions that the CPU is currently processing.

Question 9: Describe what happens when a CPU executes an instruction.

Answer: The CPU fetches the instruction from memory, decodes it to understand the operation required, and then executes the operation, often involving the ALU or registers.

Question 10: Sketch a simple block diagram of a CPU showing the main components involved in processing data.

Answer: A correct sketch includes blocks labeled 'Control Unit,' 'ALU,' and 'Registers,' connected to illustrate data flow.
