What is a disk operating system?A DOS, or disk operating system, is an operating system that runs from a disk drive. The term can also refer to a particular family of disk operating systems, most commonly MS-DOS, an acronym for Microsoft DOS. Show An operating system (OS) is the software that controls a computer's hardware and peripheral devices and allows other software programs to function. Early computers of the 1940s and 1950s did not have disk drives. Instead, they were hard-wired to carry out specific computations. Later, computers were able to store instructions loaded into the computer's memory using punch cards and then, after that, magnetic tapes. Computer memory space was limited, and when the instructions to control a computer were moved onto a disk drive, such as a floppy disk or internal HDD, it was considered cutting-edge technology. DOS is also used to describe several similar command-line disk operating systems. Early computers, such as the Commodore 64, Atari 800 and Apple II, all featured a disk operating system, including Commodore Business Machines DOS, Atari DOS and Apple DOS, respectively. DOS/360 was an OS for IBM mainframes, which first appeared in 1966, but it is unrelated to the 8086-based DOS of the 1980s.
How does a disk operating system work?When a computer is powered on it goes through various steps called the boot process. For a computer running a disk operating system, the following six steps are standard:
A disk operating system doesn't have a graphical user interface (GUI). Its interface is character-based, so users must type commands in the command line to indicate what actions they want. An example of a PC-DOS 2.0 startup screen on an early IBM PC shows the command-line interface.DOS featuresAmong the features and limitations of disk operating systems are the following. Features

Common DOS commandsMS-DOS is not case-sensitive, so commands can be typed in either uppercase or lowercase. However, other disk operating systems have case-sensitive CLIs. DOS commands include the following.
History of DOSThe arrival of the microprocessor in the 1970s started a computing revolution, and the market for personal computers (PCs) began to boom. IBM, which was known at the time for its mainframes, released the IBM 5150 Personal Computer in August 1981. To speed up the development of this new computer, IBM decided to license various components from other companies. Its first choice for an OS was the CP/M-86 software from Digital Research (DR). However, disagreements over nondisclosure agreements and licensing led IBM to choose a CP/M-like OS from Microsoft. Microsoft bought the rights to market 86-DOS, an OS based on the Intel 8086 16-bit processor. 86-DOS was created by Tim Paterson at Seattle Computer Products (SCP) and was originally called QDOS, an acronym of Quick and Dirty OS. After leaving SCP for Microsoft in 1981, Paterson worked on the PC-DOS version of 86-DOS for IBM's PC. PC-DOS was the first widely installed DOS used in PCs running on Intel 8086 16-bit processors. Microsoft produced its own almost identical version of PC-DOS called MS-DOS. As the sales of PCs grew, the ubiquity of MS-DOS grew as well. Subsequent versions featured improved performance and additional functionality, such as support for foreign and extended characters and larger HDDs. It also had enhanced memory management, an improved text editor and network support. When Microsoft first introduced Windows as a GUI for MS-DOS, early users had to type "WIN" at the DOS prompt to launch the Windows program. Windows has since evolved from being a GUI program running under MS-DOS to a full OS taking over as the default OS, though it was not until Windows XP that consumer versions of Windows stopped relying on the DOS program win.com to bootstrap the Windows kernel. The last retail version of MS-DOS was MS-DOS 6.22, and PC-DOS 2000 was the last retail release of PC-DOS. After this release, MS-DOS was still bundled as part of Windows but no longer required a separate license. It can still be run under Windows using a command processor that emulates the MS-DOS interface. There is an open source version of DOS called FreeDOS that is based on and compatible with MS-DOS. Other versions of these OSes include DR-DOS, ROM-DOS and PTS-DOS (PhysTechSoft DOS). Because of the many legacy applications, disk operating systems will continue to be in use for many years. They can be used for simple embedded systems, though securing legacy OSes against modern attacks is a concern. These OSes provide machine independence and have no licensing cost in the case of FreeDOS and other open source OSes. The takeawayDisk operating systems played a significant role in the early development of personal computing. Today, some 55 years after their initial development, they hold a place as one of the most important types of OSes in the history of computing. Microsoft recently introduced Windows 11. Find out where the Windows OS is headed and the important role it continues to play in computing. Note: The acronym DoS with a lowercase "o" is short for denial of service, a method of attacking a networked computer by sending it an abnormally high number of requests in order to exhaust its resources so that genuine users cannot gain access.
