in the GOOD OL' DAYS of computing, a
game known as
DOOM came out. and in the earliest versions, a screen that says "DOOM Operating System v1.1", and that's nothing more than a screen. It's initials are the same as it's Operating System (MS-DOS)
witch stands for Disk Operating System.
Guy 1: Hey, do you remember seeing something that
said DOOM Operating System v1.1?
Guy 2: You
mean, you saw something that said DOS?
Guy 1: No, boot-up an early version of Doom, and you'll se it.
Guy 2: Oh, alright.
Ill do that later.
