Tim Paterson programmed the first xx-DOS operating system in 1979 to run on the first 8086 (PC) computer card built by Seattle Computer. MicroSoft ended up buying this operating system and renamed it, "MS-DOS".
IBM had a whole staff of engineers. They were building computers from the early 1950s, but when a lot of small companies put little ersonal computers on the market in the late 1970s, IBM designed the first IBM PC in 1982. They commissioned Bill Gates to create an operating system for it which was called PC-DOS, but Gates also sold a modified version of it as MS-DOS. In a few years the two DOS operating systems were completely compatible. DOS was replaced by Windows after Apple marketed their own computer and operating system which had the advantage of "what you see [on the screen] is what you get" on the printout, or WYSIWYG. Windows copied that.

It was really the other way around; MS-DOS was developed to match the specifications written by IBM for the first IBM PC. The team that developed the PC was headed by Philip Don Estridge, known as Don Estridge.
The IBM PC already existed, running MSDOS, before Windows was added on.
MSDOS was the original operating system for the IBM PC. It has since been replaced in current versions of Windows by a scripting utility, as Windows is now a complete operating system and does not need MSDOS anymore.

The first IBM PC is the Compaq Portable.
It wasn't invented, it is a modified copy of the IBM PC.
It is not sure who made the pc. In 1981, IBM created the first "Personal Computer". I'm not saying IBM created the first pc, but they were the first ones who called it a Pc.
How long did it take before the first IBM PC clone was developed
The IMB personal computer was invented in november 21 1984
First PC 8080 made by IBM.
This is quite complicated; Microsoft developed PC-DOS for IBM in 1981 and shortly afterwards started selling MS-DOS - which was a different product - to other companies. However, as time passed "IBM PC Compatibility" became an important selling point and in 1987 MS-DOS and PC-DOS were essentially the same product.
