Computers are making lives easier for almost everyone.
Windows is a dominant OS used by majority of computer users.
Actually it is used mostly in fields where computers have to be used for non technical tasks.
(And hence those trolls on Facebook, describing how Linux wins).
It could be anything if it had to be C as it does not follow any order.
Logically A should be the default drive.Then why?
why did Windows do this?
Actually the reason is something historical.
And it is related to the classic floppy drives .
Before hard disks became standard(1980), floppy disks were used for booting the computers.
These were available in two sizes at that time: 5 1/4 and 3 1/2?.
Those two floppy disk drives were labelled as Local Disk (A) and Local Disk (B).
After the invention of Hard disk, floppy disk of size 8 inch came into existence.
As a result , drives other than default drive (C) labelled as D, E etc.
DVD drive and USB drive are labelled as F, G and so on.
This is the answer of our question.
