Hello Everyone,

I am very interested in logic, circuits, and truth tables in the context of Computer Science. Please, please try to help with the following questions:

1. Fill in the Blank

a. We moved away from using vacuum tubes, and now use _____________________________________, devices that can be ON or OFF, and have no mechanical/moving parts.

b. Transistors can be combined to create ______________________, which in turn can be combined to create ____________________________, which transform a set of binary inputs into a set of binary outputs.

c. ____________________________________ is a word used to describe a boolean expression that is never false.

2. Provide a truth table for each of the following types of gates:

a. 2-input NAND gate

b. 2-input NOR gate

c. 3-input AND gate

d. 3-input OR gate
