The operating systems referred to as command-based are Android and MS-DOS. These operating systems rely heavily on commands typed into a command line interface to perform tasks. In MS-DOS, users had to type specific commands to execute functions like opening files or running programs. Android, while having a graphical user interface, also allows users to interact with the system using commands in a command-line shell.
On the other hand, iOS and Windows are not typically considered command-based operating systems. They primarily rely on graphical user interfaces where users interact with the system through visual elements like icons, windows, and menus, rather than typing commands.
In summary:
1. Command-based operating systems: Android and MS-DOS
2. Not command-based operating systems: iOS and Windows
Understanding the distinction between command-based and graphical user interface-based operating systems can help users navigate and utilize different types of operating systems effectively based on their preferred interaction style.
