Internal command is a type of commands that resides within the
memory whenever DOS is active, an example of this MD - create
directory
External command is a type of command that loads from a disk.
Example of this is CHKDSK.

Command.com has built in commands, the so called "internal"
commands and a few of them are "dir", "type", "vol", "date",
etc. These commands are 'programmed' into the command.com file
and do not require other files in order to work. On the other
hand, we have commands such as "deltree", "undelete", "xcopy",
etc. that are external commands, meaning that they require the
actual application/file in order to use them, along with
command.com.

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.

Internal commands
Internal commands are DOS commands embedded into cmd.exe shell.
They are always available to the user and tend to focus on file
and folder commands. An example of a internal command would be
"CLS" to clear the screen.
External commands
External commands are not located in the shell but are in
program files stored on disk. They are a combination of .exe and
.com files mostly found in the \windows\system32 folder. An
example of a external command would be "MORE.COM" to pause the
output of a command. .com files are limited to 64K memory
mapping. .exe files are more extensive and can also include
header information and icons too. Most executable files today
are .exe files. (See links for more detailed information on
these file types.)

Internal commands are memory resident commands. They are
resident in the memory when the COMMAND.COM is loaded in the
boot up process. An example of internal command is CLS, it is
used for clearing the window/environment of cmd.
External commands are MS-DOS utilities / programs. These are the
.EXE or .COM programs located on your hard drive. They are
normally placed under C:\DOS, the default directory. MS-DOS will
load external commands if and only if you instruct to execute
them at the DOS prompt and /or in a batch program. An example of
external command is tree. It graphically displays the directory
structure of a drive or path.

Internal commands are something which is built into the shell.
For the shell built in commands, the execution speed is really
high. It is because no process needs to be spawned for executing
it. For example, when using the "cd" command, no process is
created. The current directory simply gets changed on executing
it.
External commands are not built into the shell. These are
executables present in a separate file. When an external command
has to be executed, a new process has to be spawned and the
command gets executed. For example, when you execute the "cat"
command, which usually is at /usr/bin, the executable
/usr/bin/cat gets executed.

In MS-DOS, there are two ways commands are executed: internally
and externally. An internal command is embedded into the
command.com file, and an external command, which is not and
requires a separate file to operate.
Internal commands: cd, dir, cls etc.
External commands: xcopy

Internal command - any command that resides in the command.com
file,further grouped according to their properties. Ex: VER -
displays the MS Dos version number
External command - External commands are commonly external
either because they require large requirements or are not
commonly used commands.Does not reside in the command.com.file
Ex: format - format a disk

Internal commands are the commands that are executed directly by
the shell. These commands will not have a separate process
running for each.
ex. DIR (Directory)
External commands are the commands that are executed by the
kernel. These commands will have a process id running for it.
ex. DISKCOPY
