Internal commands are built into the command interpreter of an operating system, allowing them to be executed without requiring a separate program file. They typically include commands for file management, system configuration, and process control, such as cd, dir, or echo. Unlike external commands, internal commands do not rely on external executables, making them faster to execute and often essential for basic system operations. Additionally, they operate directly within the command shell environment.
