- IBM PC DOS (Wikipedia)
IBM PC DOS (an acronym for IBM Personal Computer Disk Operating System), also known as PC DOS or IBM DOS, is a discontinued disk operating system for the IBM Personal Computer, its successors, and IBM PC compatibles. It was manufactured and sold by IBM from the early 1980s into the 2000s. Developed by Microsoft, it was also sold by that company as MS-DOS. Both operating systems were identical or almost identical until 1993, when IBM began selling PC DOS 6.1 with new features. The collective shorthand for PC DOS and MS-DOS was DOS, which is also the generic term for disk operating system, and is shared with dozens of disk operating systems called DOS.

Brooklyn is a borough of New York City located at the westernmost end of Long Island in the State of New York. Formerly an independent city, the borough is coextensive with Kings County, one of twelve original counties established under British rule in 1683 in the then Province of New York. As of the 2020 United States census, the population stood at 2,736,074, making it the most populous of the five boroughs of New York City, the most populous county in the State of New York, and the ninth most populous county in the United States. In 2022, the population density of Brooklyn was recorded at 37,339.9 inhabitants per square mile (14,417.0/km2), making it the second most densely populated county nationwide, behind only Manhattan (New York County). Had Brooklyn remained an independent city, it would today be the fourth most populous American city after New York, Los Angeles, and Chicago.
