1. Question Of The Year
Seriously, why is the drive you store things on your computer always labled C?
2. Sucky Storage
Well back when computers were first created, their storage sucked. There used to be only a few kilobytes, but now there are 500 gigabytes or 1 terabyte!
3. The Floppy
Enter the almighty floppy disk, to help save data externally.
The drives that could be added to your computer were labled A and B
5. Bye Bye Floppy
But then everyone realized how prehistoric floppy disks were, so they were discontinued...but the A & B drives remained in the computers.
6. Sticking Around
Hence why you still see drive C on your computer...the ghost of the floppy disk lives on!
