Answer 2

An acronym for Disk Operating System, in a general sense, DOS refers to just about any operating system. More commonly, it describes the operating system Microsoft developed in 1981 for IBM's line of personal computers. Though syntactically distinct, DOS shares similarities with a Unix shell. It has a command-line interface and analogs to many common Unix commands. However, DOS is a 16-bit, single-user operating system that does not support multi-tasking. It is far easier to administer than Unix, but less powerful. Compared to modern graphical interfaces, such as Mac OS and Windows.....................

Answer 3

Hi!

DOS means Disk Operating System, aka a OS stored on the Disk. OSes can also be stored on other types of memory!

DoS means Denial of Service, which often occurs during, or after a DoS attack, when a particular machine is hacked!

Good luck!

Answer 4

you have not stated your question correctly. There is DOS and there is DoS.

DOS Disk Operating System is the first popular operating system, is a command line (ie not graphical like windows) interface used to give instructions to a computer.

DoS Denial of Service.
A DoS is an attack on a computer in attempt to deny users of it's services. (Simple ain't it).

Disk Operating System, the first popular operating system used by non-Macintosh computers. If anyone is still using this as their main operating system, they either are running an old machine or are one of those crotchety curmudgeons that hate change.

An acronym for Disk Operating System, in a general sense, DOS refers to just about any operating system. More commonly, it describes the operating system Microsoft developed in 1981 for IBM's line of personal computers. Though syntactically distinct, DOS shares similarities with a Unix shell. It has a command-line interface and analogs to many common Unix commands. However, DOS is a 16-bit, single-user operating system that does not support multi-tasking. It is far easier to administer than Unix, but less powerful. Compared to modern graphical interfaces, such as Mac OS and Windows, it is also not particularly user-friendly.

DOS began as QDOS (Quick and Dirty Operating System), a variation of an older operating system called CP/M. It was initially produced by Seattle Computer Products; Microsoft then bought the rights to it and re-engineered it for IBM's new line of PCs. At this point, two distinct but similar versions of DOS emerged:

PC-DOS, which is what IBM distributed with its computers


MS-DOS, which Microsoft licensed to clone vendors
In 1985, Microsoft released Windows 1.0, a graphical interface that ran on top of DOS. Providing a friendlier environment than the DOS command-line, Windows grew in popularity, especially after its 3.0 release in 1990. Other graphical interfaces, such as GEOS, were also developed for DOS, but none have had widespread popularity.

With the release of Windows 95 and Windows NT, DOS has faded in importance. Though Windows 95 includes a built-in version of DOS, it provides many of the functions DOS used to be responsible for. Windows NT is not based on DOS at all, though it does include a DOS-like command line interface. As 32-bit, and in the future, 64-bit, applications become the norm, DOS will become increasingly inadequate. Nevertheless, there are still many programs, especially games, that require DOS to run. It also provides a convenient command-line for those situations where a graphical interface is less efficient.

Answer 6

DOS is Disk Operating System.
It's used before Windows was released

Answer 7

Department of State (in US)

Answer 8

not only was it used before windows...win3.1 win95 and win98 all ran on dos...
DOS could run one program at a time, hence it ran the Windows OS

Definitions of DOS:

* Disk Operating System: The name of the operating systems on most brands of personal computer contains the acronym DOS. Often when DOS is used without further description, the operating system being referred to is either PC DOS, the operating system used on IBM personal computers, or MS DOS, the variety of DOS that runs on IBM compatible computers.

* Disk Operating System.

* Acronym for Disk Operating System.

* A command line operating system that Windows runs on top of. Bill Gates created DOS while working for IBM.

* Short for denial-of-service attack, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. For all known DoS attacks, there are software fixes that system administrators can install to limit the damage caused by the attacks.

* Disk Operating System. This is the operating system used by the original IBM PC and many since.

* A set of programs that instruct a disk-based computing system to manage resources and operate related equipment.

* Acronym for disk operating system. The term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers.

* Disk Operating System - A type of operating system for a personal computer.

* (Disk Operating System) simple operating system developed by Microsoft, allows extensions by other programs.

* Disk Operating System. A disk manager and the program that allows computer / user interaction. DOS environment

* Most common operating system for the IBM-compatible or personal computer.

* Denial of Service. An electronic attack whose purpose is to prohibit an opponent the use of a program or an entire system.

* A widely used PC operating system. DOS has been largely supplanted by Windows of some kind or another on most desktops.

* Disk Operating System. The original system used for PCs. You type in commands instead of pointing and clicking.

* Microsoft's version preceded Windows but that has receded in importance with each new version of Windows.

* A computer operating system designed for use with a disk. Languages, application and utility programs can be transferred quickly between CPU memory and disk storage.

* (Disk Operation System)--The standard operation system for all computers advertised as "IBM Compatible".

* Department of State: the federal department in the United States that sets and maintains foreign policies; "the Department of State was created in 1789"

* * A disk operating system is an operating system that resides on a disk. This term commonly refers to a group of similar operating systems for the IBM-compatible personal computer, including MS-DOS, PC-DOS, DR-DOS, and FreeDOS.

* Dos is a two-bass indie/punk band featuring the former husband-and-wife team of Mike Watt (Minutemen, fIREHOSE, The Stooges) and Kira Roessler (Black Flag).
