Logic Gates in Computers

logic gates are a way of connecting up the abstract mathematical or logical operations that we're trying to get our computer to perform with the real hardware. Logic gates almost always have two inputs and one output. The not gate, which is the simplest type of gait, takes in one input and gives one output. Each input and output you can think of as corresponding to a single electrical wire which carries a voltage of either high or low. In other words, when the input is zero, the output is one, and so on. That's why binery works so well in digital computers because it's much easier to build devices that tt work on that basis.
