DOS Definition

DOS (Disk Operating System) – is a general term for a variety of early IBM PC-compatible OSes, replete with the methodic handling of storage devices and executing file operations. Another operating system software that really had attained special popularity was released in between years 1980 and 1990 for IBM PCs, perhaps MS-DOS by Microsoft. Using DOS, one can execute some basic operations, which include items like file management, disk formatting, and even program execution. DOS is prompt-driven to a command, meaning any time a user would want his or her command processed, he would have to type textual commands to operate functions.

It was efficient and, because of the hardware in those days, simple, making it one of the most commonly used operating systems. However, DOS was an indispensable forerunner to a large extent in the personal computing revolution because further modern operating systems’ development—Windows, MacOS, and Linux—replaced it to a great extent.
