When you open computer resources on a Windows PC, you find that the drive where the operating system is installed is C: and that the CD / DVD drive is the D: drive. If you insert a USB stick, it takes the name F: and, for any other disks or connected storage units, the letters of the next alphabet.
One might then ask what happened to the letters of the drives A: and B: and if they could be used instead of C: and D:.
People who have been using the computer for many years already know what the answer to the title question is, while younger people may miss the meaning of this literal assignment.
To understand what happened to drives A: and B: we must take a step back in the history of computers, when the first IBM PCs did not have a hard disk but only a floppy disk reader .
This player was drive A: where floppy disks had to be inserted to load programs.
Two more floppy disk drives were mounted on the more expensive and more advanced computers, one for loading programs, the other for saving data; this second reader was identified by the computer with the letter B:.
With the transition from 5.25 floppy disks to smaller 3.5 "plastic disks it was common to have both drives in a computer, one was A: and the other B:.
Until then there was absolutely no need to change these letters or allow the user to reconfigure them.
Over time, hard drives became cheaper and hard drives were naturally called C: drives.
The C: disk had become a standard for programs and also for the computer boot BIOS software and is today the starting point of every Windows PC.
So if you can assign letters from C to Z for each drive on your computer, you can use A and B again on your PCs without a floppy disk drive "> disk management.
