Boolean Logic is essential and foundational knowledge in Computer Science and it all started with a man named George Boole. In this topic you will study the different logic gates and understand how inputs produce an output (and how these circuits are effectively what make up a computer!).
The three main gates you will learn about are the AND, OR and NOT gate. There are, however, other gates like the XNOR gates and the below IQ logic puzzle is based on understanding the XNOR gate. If you know the answer, see if you can explain it to the class.
