ibm pc dos (acronym for international business machines corporation personal computer disk operating system) was an operating system for the ibm personal computer, manufactured and sold by ibm from the 1980s to the 2000s. before version 6.1, pc dos was an ibmbranded version of msdos. for versions 6.1 and later, development diverged and pc dos became an independent product.
the ibm task force assembled to develop the pc decided that critical components of the machine, including the operating system, would come from outside vendors. this radical break from company tradition of inhouse development was one of the key decisions that made the ibm pc an industry standard. but it was done out of necessity, to save time. microsoft was eventually selected for the operating system.
