It’s not that computers don’t have B drives. In initial stage personal computers didn’t have hard discs- they were equipped with two floppy drives called drives A and B. Later, a hard disk was introduced and was labelled as C drive. Other drives like CD drive, DVD drive, flash drive and others were labelled D, E etc. If you have a computer having two floppy drives, then they are called A drive and B drive.
