Question

 Which of the following operating system is not GUI based? 
1. iOS
2. MAC OS
3. Android
4. MS- DOS

Answer 1

Correct Answer - Option 4 : MS- DOS

The correct answer is MS-DOS.

• MS-DOS is not GUI-related.
• MS-DOS stands for Microsoft Disk Operating System. It offers a file system to organize, read and write files to the disk storage.
• A graphical user interface (GUI) is a type of user interface through which users interact with electronic devices via visual indicator representations.
• GUIs graphically display information and related user controls, unlike text-based interfaces, where data and commands are strictly in text.
• Today, each OS has its own GUI (such as Ubuntu for Linux). Software applications (Microsoft Word and Excel, or Adobe Photoshop) use these and add additional GUIs of their own.
• A GUI uses windows, icons, and menus to carry out commands, such as opening, deleting, and moving files.
• Hence, iOS, Mac OS, and Android are related to GUIs.
