Binary 1 of 28 Binary Can be one of two states? 2 of 28 What does 1 represent in binary? On True Yes High 3 of 28 What does 0 represent in binary? Off False No Low 4 of 28 What does A == B mean? A is equal to be 5 of 28 What does A < B mean? A is less than B 6 of 28 What does A > B mean? A is greater than B 7 of 28 What does A != B mean? A is NOT equal to B 8 of 28 What does A ≤ B mean? A is less than or equal to B 9 of 28 What does A ≥ B mean? A is greater than or equal to B 10 of 28 What are logic gates? The building blocks of circuits using the binary system 11 of 28 Why do computers need logic gates? Logic gates use binary system, and computers understand binary language. 12 of 28 What are the 3 main types of logic gates? AND OR NOT 13 of 28 How do you get a high AND Gate output? Both inputs must be high 14 of 28 I inputted 0 into a NOT gate? What's the output? Why? 1 Because the output of a NOT gate is the opposite to the input. 15 of 28 How does the OR Gate work? If one or more of the inputs is high, the output will be high. The output will only be low, if BOTH inputs are low. 16 of 28 I inputted 1 into a NOT gate? What's the output? 0 17 of 28 What is the logic notation of an AND Gate? X = A AND B 18 of 28 What is the logic notation of an OR Gate? X = A OR B 19 of 28 What is the logic notation of a NOT Gate? X = NOT A 20 of 28 What is the logic/boolean expression of an AND Gate? X = A /\ B 21 of 28 What is the logic/boolean expression of an OR Gate? X = A \/ B 22 of 28 What is the logic/boolean expression of a NOT Gate? X = Inverter A 23 of 28 What are truth tables for? Show the possible outputs of a logic gate, depending on inputs 24 of 28 How many outputs for a NOT Gate? Not Gate has one input so 2¹ = 2 possible different outputs 25 of 28 How many outputs for a OR Gate? Or Gate has two inputs so 2² = 2 possible different outputs 26 of 28 How many outputs for a AND Gate? And Gate has two inputs so 2² = 2 possible different outputs 27 of 28 What is the formula for truth tables? 2ⁿ ⁿ is the total number of inputs 28 of 28
