Logic Gates

1. AND

2. NOT

3. OR

4. ^ = AND

5. AND:

   • 0 1 0
     • 1 0 0
       • 0 0 0
         • 1 1 1

6. NOT:

   • 0 1
     • 1 0

7. OR:

         • 1 1 0

8. V = OR

9. ¬ = NOT

10. Used to determine whether the logical switches in the CPU are On / Off

11. Exam Techniques

    • Always label inputs and outputs
    • Don't forget to draw the circle on the NOT
    • Draw whats in the brackets first (BIDMAS)
    • A circle infront of an AND / OR inverts the gate making it a NAND / NOR
