Explanation:
Commands are sentences in which someone is told to do something. Other sentence types include questions, exclamations, and statements. Because command sentences tell someone to do something, they usually, but not always, begin with an imperative (bossy) verb.
A command in computers is a specific order from a user to the computer's operating system or an application to perform a service, such as "Show me all my files" or "Run this programme for me." Operating systems without a graphical user interface (GUI), such as DOS, provide a simple command line interface.
