HDD

This is your computer's short-term memory. Things are stored here while they are deleted when the computer is no longer using the data. The more RAM a device has, the more short-term memory it has. So a computer with more RAM will be able to run more programs at once without becoming slow. These days, 8GB of RAM is the standard but you can get by with 4GB, and with more than 8 your computer will be much faster!

Random Access Memory (RAM)

A computer Hard Drive is where files and programs are stored. An HDD is a specific type of Hard Drive which has a spinning disk. Spinning Hard Drives have been around for much longer than large solid-state drives. They're cheaper, and typically able to hold more data. Unfortunately, they are also easier to break when knocked about and are not as fast as a solid-state equivalent.

Hard Drive (HDD)

Solid State Drives use flash memory, the same technology that is in thumb drives, SD cards, and most mobile devices.Flash memory is much faster and is usually used to hold a computer's operating system to make the PC load faster. While this technology has improved drastically and we can hold up to 100TB on one SSD now, it is also much more expensive than a traditional hard drive.

Solid State Drive

The Central Processing Unit is exactly what it sounds like. This is the brain of your computer; information is input into this device to be processed and then output as new information. This is the most complex part of your computer, only three main companies produce these: Apple, Intel, and Radeon. In this device, the CPU is hidden by the fan unit because this is where most of the heat in your computer comes from.

Central Processing Unit (CPU)

Pretty much all digital systems have some kind of motherboard. The Motherboard connects all the other components and acts as a junction to route the relevant information to the correct device. Your Motherboard also has BIOS which is a program that allows you to change how the different components interact with each other.
