2.4.1 Computational logic

Why is data represented in binary form?

• 1s and 0s are easy to understand

• 1s and 0s represent on/off signals and pass through gates

• Denary is easy to understand

• 1s and 0s are to complicated to understand

What type of gate?

• AND

• OR

• NOT

• IF

What does this diagram represent?

• B AND Y = A

• Y = A AND B

• A AND Y = B

• A AND B = Y
