2.4 Computational logic

1. Binary is representation of the presence of electricity

   • Logic gates take inputs and convert them to a output

2. Key words: Logic gate, translator, Bit (Binary digit), Logic circuit, AND, OR, NOT(Inverter)

3. Binary is used to change bits and perform calculations with a computer

   • created by using transistors
     • There are 3 basic logic gates AND, OR, NOT
       • Every logic circuit can be made up from these 3 logic gates

4. The output of logic gates can be shown through truth tables

   • Truth tables show what an output will be based on the inputs

5. The AND gate only has an input of 1 if both A and B are 1

   • The OR gate has an output of 1 if either A or B 1
     • The NOT gate has a 1 input only, it inverts or swaps this input
