What is mean Ms-Dos ??

MS-DOS (/ˌɛmɛsˈdɒs/ em-es-doss; short for Microsoft Disk Operating System) is an operating system for x86-based personal computers mostly developed by Microsoft. It was the most commonly used member of theDOS family of operating systems, and was the main operating system forIBM PC compatible personal computers during the 1980s to the mid-1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the Microsoft Windowsoperating system.

MS-DOS resulted from a request in 1981 by IBM for an operating system to use in its IBM PC range of personal computers. Microsoft quickly bought the rights to 86-DOS from Seattle Computer Products,^[7] and began work on modifying it to meet IBM's specification. IBM licensed and released it in August 1981 as PC DOS 1.0 for use in their PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, in subsequent years the two products went their separate ways.

During its life, several competing products were released for the x86 platform,^[8] and MS-DOS went through eight versions, until development ceased in 2000. Initially MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well. Progressive version releases delivered support for other mass storage media in ever greater sizes and formats, along with added feature support for newer processors and rapidly evolving computer architectures. Ultimately it was the key product in Microsoft's growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI. It is a flexible operating system, and consumes negligible installation space.

What is ISO File?

In common use, an "ISO File" is a file that contains the complete image of a disc. Such files are often used when transferring CD/DVD images over the Internet. Depending on who you're talking to, "ISO File" may refer to all disc image files or only certain kinds.  Going by the more restrictive definition, an "ISO File" is created by copying an entire disc, from sector 0 to the end, into a file. Because the image file contains "cooked" 2048-byte sectors and nothing else, it isn't possible to store anything but a single data track in this fashion. Audio tracks, mixed-mode discs, CD+G, multisession, and other fancy formats can't be represented.  An ".ISO File" file can be manipulated in a number of ways: it can be written to a CD or DVD disc; mounted as a virtual drive; or viewed with PowerISO.
