What is MS-DOS?
MS-DOS stands for `` MicroSoft Disk Operating System (Disk Operating System of MicroSoft) and is the name of one of the operating systems for computer systems Ethics based on an x86 architecture and designed by the American software company Microsoft. It was popularly known as `` DOS.
This operating system was preinstalled on most computers in the 1990s, and it was the basic software for human interaction with the computer. To do this, it requires that the user enter some of the commands manually, using the keyboard, choosing them from a possible list of instructions called commands that he should know. .
There were two series of commands `` MS-DOS '': internal and external . The first, also called residents, were automatically loaded at the beginning of the operating system of the computer, from a file stored in the name of command.com; For that, it was possible to activate them without having the `` GOD '' in the unit from which they are executed.
The external commands, on the other hand, were stored in specific files of a transient type, but which should be kept on hand to be able to invoke the specific commands. desired

The MS-DOS was born in 1981, created as a basic interface for IBM PC personal computers, from a much more primitive previous version known as 86-DOS or QDOS, belonging to Seattle Computer Products. Version 1.0 of the MS-DOS appeared in 1982, along with its version preinstalled on PC products: PC-DOS.
It was used massively until the mid-1990s, when it was replaced by Windows systems; Despite being based on DOS, these last ones offered the user a much nicer graphical interface than the arid DOS commands. Today, much of its structure is preserved in basic and essential processes of some Microsoft Windows systems.
