DOS by default is not capable of multi-tasking. However, there are some shell and TSRs designed to allow you to switch between different DOS apps.
It depends what you mean by widely used and PC. The widely used Apple II computer used Apple DOS while another operating system which was widely adopted (including versions for the Apple II) was called CP/M which was created by Digital Research. They went on to create DR-DOS which was one of the versions of DOS used on the early IBM personal computers. Microsoft had purchased an operating system called QDOS which was adapted by IBM into PC-DOS for their own computers and by Microsoft as MS-DOS for use on computers not made by IBM but following their design (known as IBM clones). These became increasingly popular and so MS-DOS became widely adopted and PC-DOS faded away. Apple went on to develop the Macintosh with its graphical user interface which Microsoft copied to create their Windows operating system.
MS-DOS ended with Windows NT. It used file command.com to interpret all DOS commands. Win 2000, XP, Vista use a DOS Shell which emulates DOS but is not really DOS.
MS-DOS 6.22 was the last stand-alone version of MS-DOS. Some believed that MS-DOS 7.0 was the last version of MS-DOS since Windows 95 reported MS-DOS as MS-DOS 7.0. However, this was just a shell in Windows and not a stand-alone version of MS-DOS.
A stand alone operating system is a system that is independent of another for example windows 3.1 ,95,98 were all a shell based on the ms-dos operating system to put it in simpler terms windows was a dressed up version of ms-dos with all the bells and whistles to be more appealing to the eye and be more user friendly . later versions of windows were independent of the ms-dos operating system hence they are known as "stand alone operating systems" .
MS-DOS, PC-DOS, FREEDOS.
No. You can go to a DOS like prompt and use DOS like commands, however, current versions of Windows are no longer based on DOS.

There are multiple versions of DOS that have been available. * MS-DOS was manufactured by Microsoft. * PC-DOS was manufactured by IBM. * DR-DOS was manufactured by Digital Research Inc. There are other versions of DOS available, but the three listed were the most widely distributed.

Yes, both versions of Windows use DOS..
DOS
Visual Basic is a high programming language that evolved from the initial DOS version called BASIC. Its coding is more in English language. Different versions like Microsoft QBASIC, QUICKBASIC, GWBASIC and IBM BASIC have been developed by different companies.
DOS 1.x and 2.x: These ancient DOS versions support only the FAT12 file system, used today primarily for floppy disks. If you're still using DOS 1.x or 2.x, man do you need a new computer! :^)DOS 3.x through 6.x: These are more common versions of DOS for older PCs running either straight DOS or Windows 3.x. DOS 6.x was especially popular; millions of copies of these operating systems were sold. DOS 3.x through 6.x support the older FAT12 and the newer FAT16, which was the file system standard for many years in the PC world.DOS 7.0: MS-DOS 6.22 was the last "standalone" version of DOS sold by Microsoft. After DOS6.22, Microsoft sold DOS only as the underpinnings of other operating systems, such as Windows 95/98/ME. The first of these was MS-DOS 7.0, which runs "underneath" the first Windows 95 version (Windows 95A). It supports FAT12, FAT16 and VFAT, the enhanced version of FAT that includes support for long file names.DOS 7.1 and later: These versions of DOS underlie Windows versions from Windows 95 OEM Service Release 2 (Windows 95B) and later. They support FAT12, FAT16, VFAT and FAT32.
DOS and DOS-like commands are still usable in modern versions of Windows, and can sometime be the only way to accomplish a given task.
The modern versions will not work on DOS. The very early versions did, running through the windows environment before Windows became an operating system. These would be versions like Windows 3.1 or Windows 3.11 which you would have found on computers in the early 1990s.
