Answer / naveen badam
Internal commands are the commands that are executed
directly by the shell. These commands will not have a
separate process running for each.
External commands are the commands that are executed by the
kernal. These commands will have a process id running for
it.

Answer / kasam
in MS-DOS there are two ways commands are executed. An Internal command, which is a command embedded into the command.com file, and an external command, which is not embedded into command.com and therefore requires a separate file to be used.
For example, if your computer does not have fdisk.exe and you try using the fdisk command, you would receive an error "Bad command or file name." Fdisk is an external command that will only work if fdisk.exe, or in some cases, fdisk.com, is present.
However, as long as MS-DOS is running on your computer internal commands such as the cd command will always be available and does not require any other files to run.
