Every fully functioning computer is made of the same basic components and here I’ll walk through the basic hardware you'll need for your first build. There are several components a computer. However, it’s important to first understand what each component does.
The processor (CPU) is like the brain of a computer, the thing that carries out the tasks you give it. Better CPUs can perform more tasks at once, and perform them faster. Not everyone takes full advantage of their processor's full speed, so the high-end processers are only really needed if you're performing intensive things like gaming or video editing. It's also one of the most expensive parts of a computer, so if you aren't doing these types of things, you don't need to buy the latest and greatest.
Another expensive part is the motherboard connects all the other components to each other, and is the physical base that you build everything else onto. It contains a lot of your machine's core features, like the number of USB ports, the number of expansion cards you can put in (like video, sound, and Wi-Fi), and also determines how big your computer will be. The motherboard you buy will depend on the type of user you are.
The case holds all of your computer's parts together. For the most part, a case is less about features that affect how your computer runs and more about features that affect you and your home. Still, it's an important consideration that is dependent on your other choices, so you might want to think about everything before buying one. Make sure the case buy will hold motherboard.
RAM, or Random Access Memory, is like your computer's short-term memory. It stores data your computer needs quick access to help your programs run faster, and help you run more programs at one time. That basically means the more you want to do at once the more RAM you’ll need.
The graphics card, or GPU, is a processor designed to handle graphics. It's what you hook
