We have C Drive on Computer. But we don’t have A & B WHY?

Because the initial state of the computer we had two difference small size capacity of floppy disk 5.25inch [1.2MB] and 3.5 inch [1.44MB]. We named those are A and B. Then we got permanent default high capacity drive. We named that as C Drive.
