No Dos is still used in many things today. Many programs are Windows Only due to them using Dos Files.
Technically there is no differences between Windows and DOS. DOS is an acronym for Disk Operating System which every computer has to have to operate.
Pretty much yes, up until Windows XP there were versions of Windows that ran "on top" of MS-DOS, but XP (based on Windows NT) removed that requirement. MS-DOS sort of lives on as the Windows command prompt which supports most of the MS-DOS commands and allows people to run MS-DOS programs.
For starters, DOS is practically obsolete. DOS stands for Disk Operating System and was mostly a Command Line Interface, or CLI for short, OS. Windows XP is a GUI, Graphical User Interface, based OS. So in other words, they are both completely different Operating Systems.
Basic was one of the very first programming languages used in DOS. It is not object oriented and is obsolete. If you want to learn to programe start with Visual Basic no BASIC.
