Internal Commands
Internal commands are nothing but the built-in commands that are shipped along with the

External Commands
External commands are the commands that are often created while installing a new application
and these commands mostly have no use except calling that application and support files. Few external commands can only be executed in the ‘Run’ dialog box (start --> Run), but not on the command prompt, and those commands include ‘firefox’. The ‘firefox’ command can be executed only from the run line, that too if the firefox application is installed on that machine and it won’t work on the command prompt. Likewise the ‘firefox’ there are various other external commands such as the “PsTools” which includes commands like, PsExec, PsFile, PsGetSid, PsInfo, PsKill, PsList, PsLoggedOn and so on.
