We just learned about the Video Card.
Another part of a computer is the Hard Drive, also called a hard disk drive or HDD.
When you are working on the computer and you draw a picture, or write some words that you want to save in a document or spreadsheet, that information has to get saved somewhere on the computer so that it will be there again the next time you turn on the computer.
The hard drive is where the computer saves whatever you give it, whether it's a video, a song, a picture or a document.
Hard drives are usually made up of little magnetic metal discs that spin around almost like music records or CDs.
The computer gets the information from the discs, and puts new information on the discs.
Other types of ways to store files are called Solid State Drives, or SSDs.
These don't have spinning magnets in them, they are more like a big USB memory stick.
