What happens inside of a computer might sound complicated, but it's a lot simpler than it seems!

Motherboard

The motherboard links every computer part together.

The motherboard is a hub where all the information from these different components connect.

Central Processing Unit (CPU)

The Central Processing Unit (CPU) is the brain of the computer. The CPU does most of the work when it comes to processing actions and codes.

Graphics Processing Unit (GPU)

The Graphics Processing Unit (GPU) manages visual data. It processes any picture or video you see on your screen.

Some computers do not have a GPU. Many low-end computers use something called integrated graphics, which is a chip that is pre-installed in the motherboard to process graphics. Regular GPUs are still much faster, though.

Random-access Memory (RAM)

Random-access Memory (RAM) stores all the data your computer uses at any given moment.

  • RAM stores short-term information.

  • Most modern computers use 8 to 16 gigabytes (GB) of RAM depending on the power needed to run certain software.

Storage

A storage device is where your computer holds every piece of information. If RAM is like a desk, the storage device is like your filing cabinet.

There are 3 types of storage devices:

  • Hard Drives are the cheapest form of storage. They are typically capable of storing the most data but are the least reliable due to the moving parts inside.

  • SSD is much faster and more reliable than hard drives.

  • NVME SSDs are the smallest form of storage, and most expensive, but fastest overall.

Quiz

You want to upgrade your storage device to be faster, but you are on a budget. Which storage device would you upgrade to?

Power Supply

Power Supply Unit

The Power Supply converts the power that comes from your electrical outlet to an amount of power usable for your computer.

The number of watts for a power supply can range anywhere from 200 to 1800 watts. This all depends on the amount of power your computer needs.

To calculate this amount, multiply the total amps of all components by the total volts of all components.
