If you just want to learn more about your computer's hardware, software and the overall system, here's a good place to start! Read the tutorials, then try the exercises provided. If you have trouble with the review questions, go over the tutorials again. You'll be surprised at how much you learn!

The computer hardware tutorials, labs and review questions may also be helpful for those preparing for CompTIA's A+ (Aplus) Certification exams.
This site was designed to make choosing your hardware components easy. We've tested all kinds of hardware, scoured through review after review, and discussed components and their performance with real-world users to find the best components to recommend to you. We hope you will find these recommendations helpful. To begin, just select the component you're looking for from the menu.
