What is it?

SSD is a type of storage drive similar to a traditional hard disk drive (HDD).

Why does it matter?

Without moving parts, SSDs are thinner, faster, and more durable than HDDs, allowing for smaller PCs with greater battery life. 2

What is it?

RAM is your PC’s “working” memory.

Why does it matter?

It helps with performance when doing things like running apps and browser tabs. More RAM means you can do more things at the same time.

What is it?

The brain of your PC. It tells the other components in it what to do.

Why does it matter?

It performs the instructions the operating system tells it to. Without it, your PC doesn’t run.

What is it?

It helps your PC do graphics-intensive tasks, like photo or video editing and games.

Why does it matter?

It frees your CPU for other tasks, allowing for better performance.
