Question 2.
What does ALU stand for?
Show hintHide hint
It handles arithmetic operations.
3Question 3.
What is a demultiplexer?
- A circuit that takes multiple inputs.
- A circuit that routes one input to multiple outputs.

- True
- False
Show hintHide hint
Think about how memory impacts the output.
Question 5.
Design a 4-bit ALU that can perform addition, subtraction, AND and OR operations using logical gates. Explain your design.
Show hintHide hint
Think through how you would wire the gates and operations effectively.
Question 6.
