How do you exit DOS?

• A. By typing EXIT
• B. By typing QUIT
• C. By closing the command window
• D. By shutting down the computer

Answer: (A)

The correct method to exit DOS is indeed achieved by typing "EXIT." When this command is entered at the command prompt, it signals the operating system to terminate the current command-line session and return to the previous one, if applicable. This is the straightforward and intended way to exit the command line interface gracefully, allowing for any cleanup that needs to occur before the window closes. While there are other methods to leave the DOS environment, they do not represent the standardized or recommended approach. For instance, typing "QUIT" does not have any recognized function in DOS and would result in an error, as it is not a valid command. Closing the command window or shutting down the computer are alternative methods to exit, but they do not provide the same procedural benefits as typing "EXIT." Closing the window may terminate processes abruptly without allowing them to finish executing properly, and shutting down the computer is an extreme measure that affects all applications and services on the system rather than just ending the DOS session. Thus, using "EXIT" ensures a clean and safe exit from DOS.
