Boolean Logic & Logic Gates: Crash Course Computer Science #3

Today, Carrie Anne is going to take a look at how those transistors we talked about during the last episode can be used to perform complex actions. With just two states, on and off, the flow of electricity can be used to perform a number of logical operations, which are guided by a branch of mathematics called Boolean Algebra. We’re going to focus on three fundamental operations - NOT, AND, and OR - and show how they were created in a series of really useful circuits. These simple electrical circuits lay the groundwork for our much more complex machines.
