What parts are needed

This page is going to show you the most important parts that go inside a computer case. The most vital part is the Central Processing Unit, which most people just call the CPU. You can think of the CPU as the brain of the computer because it handles all the instructions and math needed to run your programs. It sits right in the middle of the motherboard, which is the large circuit board that acts as the body connecting every other part together. When you are picking out a CPU and a motherboard, you have to make sure they are compatible so they can talk to each other correctly. Without these two pieces working in harmony, your computer would not be able to turn on or process any information. Choosing these parts is usually the first and most important step for any new builder.

Another very important part of your build is the memory and the storage. Memory is often called RAM, which stands for Random Access Memory. RAM is like your computer's short-term memory; it keeps track of the apps you have open right now so you can switch between them quickly. On the other hand, your storage—usually an SSD or a Hard Drive—is like long-term memory. This is where all your photos, games, and files stay even when the computer is turned off. Most modern builders prefer to use an SSD because it is much faster than an old-fashioned hard drive. Having a good balance of both fast RAM and plenty of storage space will make your computer feel snappy and responsive. It is always a good idea to buy a little more than you think you need so you don't run out of space later.
