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!!!) :-)

In DOS systems, an internal command is any command that resides in the COMMAND.COM file. This includes the most common DOS commands, such as COPY and DIR. Commands that reside in other COM files, or in EXE or BAT files, are called external commands
