Welcome to our free online computer hardware classroom!
Computers are all around us and they are an essential part of most of our lives. Whether it's work, play, or communication, they have transformed the way we live.
We've put together this collection of computer hardware tutorials to help beginners feel more confident around computers and to help certification candidates pass their CompTIA A+ exams.
Computers are like cars - they are made up of many parts, each doing its own thing to make the system function as a whole. Our free tutorials go under the hood to explain what these parts are and what they do.
To get started, use the tutorial menu on the left side of the page.
