Binary data, logic gates and truth tables

Question	Answer
Explain why data is represented in computer systems in binary form	Binary is used to encode data using the values 0 and 1 Each 1 or 0 is called a bit and a string of 8 bits is called a byte

If the output of a circuit is high or ON, it is represented as .....?	1
If the output of a circuit is low or OFF, it is represented as .....?	0
ON = ?	TRUE
O = ?	FALSE
What is a logic gate?	Where transistors are wined together in circuits to perform logical calculations
What's a truth table?	Truth tables determine all of the possible input combinations and the output of logic gates
