File extension COM description:
The file name extension .com has been used in various computer systems for different purposes. Originally, the term stood for "Command file" and was a text file containing commands to be issued to the operating system. This was the practice on many of the Digital Equipment Corporation mini and mainframe computer systems going back to the 1970s.With the introduction of microcomputers this use of files ending with the extension .com changed. In MS-DOS and compatible DOSes, and in 8-bit CP/M, a COM file is a simple type of executable file. The name of the file format is derived from the file name extension .com (not to be confused with the .com top-level domain), which was originally the extension used for such files. However there is no actual association between the file format and the file name extension in any but CP/M and very early versions of MS-DOS.

MS-DOS (short for Microsoft Disk Operating System) is an operating system commercialized by Microsoft. It was the most commonly used member of the DOS family of operating systems and was the dominant operating system for computers based on the Intel 8086 family of microprocessors, particularly the IBM PC and compatibles, during the 1980s. It was gradually replaced on consumer desktop computers by operating systems offering a graphical user interface (GUI), in particular by various generations of the Microsoft Windows operating system. It was originally known as QDOS (Quick and Dirty Operating System) and 86-DOS.
MS-DOS was originally released in 1981 and had eight major versions released before Microsoft stopped development in 2000. It was the key product in Microsoft's growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI.
