What Does It Look Like?
What Does It Do?
Hard drives are used to store your software programs and information created from them. Imagine it being a giant filing cabinet inside of your computer, holding all your information.
The benefits of this, is that you can permanently store all of your software programs such as:
- word processors
- spreadsheets
- Games (yeah!)
Years ago when software programs were relatively small, hard drives were not needed. You could just save everything to floppy disks.
But today, software programs take up so much space that you would need 100's even 1000's of floppy disks to hold a single program. Hard drives can store vast amounts of data, are exceptionally fast and become cheaper as technology improves.
