Boolean Logic

What is the boolean expression for this logic circuit?

• Q = NOT (A OR B)

• Q = NOT A AND B

• NOT A OR B = Q

• Q = (NOT A) OR B

This is the truth table for which logic gate?

• 
• 
• 

In this logic circuit, if A = 0 and Q = 1, what is B?

• 0

• We can't say

• 1

In this logic circuit, what is Q if the inputs are: A=0, B=1, C=0?

• 0

• We can't say

• 1

What is the best explanation for why a computer uses boolean logic to manipulate True and False values?

• It can only understand 0s and 1s

• It runs instructions in a binary code

• It doesn't have enough memory to store numbers above 1

• It uses transistors which can only be on or off

A single logic gate is an electronic component made of transistors, which does what?

• Performs calculations such as binary addition

• Performs binary shifts left and right

• Combines boolean inputs to produce a boolean output

• Executes instructions stored in the main memory

Which of these are boolean operators, implemented in the computer as logic gates?

Check all that apply

• NOT

• MOD

• OR

• AND

• DIV

Which logic gate is this?

• AND

• NOT

What is the output Q if the inputs to this logic circuit are both 0?

• 0

• We can't say

• 1

What is the boolean expression for this logic circuit?

• A OR B AND C = Q

• Q = (A AND B) OR C
