Study Notes
Operating System Components
- Operating systems need to interact with users for tasks.
- User interface handles user communication.
- Older systems, called shells, used text-based interfaces (keyboard and monitor).
- Modern systems use graphical user interfaces (GUIs).
- GUIs represent objects (files, programs) as icons.
- Users issue commands via input devices (e.g., mouse).
- Mice, styluses, or touch screens are used for input.
- Touchscreens allow manipulation with fingers.
- Research explores 3D interfaces for communication using projections, touch, and sound.
