Learning these terms can be daunting, but when you’re managing files, it’s useful to know how much space they take up. 

This is another way of remembering it:

-A thousand Bytes is a Kilobyte

-A thousand Kilobytes is a Megabyte

-A thousand Megabytes is a Gigabyte

-A thousand Gigabytes is a Terabyte

There are some measurements even larger than this, but you probably won’t need to know about them any time soon.
