MS-Dos was first released in August 1981. It remained a staple of computer users until its final release in September 2000.

Internal DOS command are those which were pre loaded into the Operating system. (I am talking about the DOS ver 3.2) In contrast to the External DOS commands, which are the utilities developed for different functionalities (usually .exe and .com files) eg. FORMAT, DISKCOPY,FDISK which are to be used from the storage medium they are in; in the floppy drive (or a Hard Disk Drive!!! on a Intel 286 based AT computer with a storage capacity of 20 MB!!! How large compared to stacks of floppies each with 360 KB capacity!!!) :-)

Creates a new directory or folder.

A parameter is a command-line switch or an argument to a function. We use parameters to specify the input variables for the commands or functions we invoke. For instance, when we want to list the contents of a directory or folder, we have to pass the directory or folder path to the appropriate command so that it knows which directory or folder to process.

MS-DOS 1.0 came out in July of 1981. There were other versions before it but that was pretty much the first version sold to the public.

They don't offer any real advantages other than perhaps being slightly faster.

yes yes
