Operating System User Interface

The part of an operating system that handles communication between the user and the computer.

Shell User Interface

Older, text-based user interfaces that use text commands entered via keyboards to communicate with the computer.

GUI

Graphical User Interface; uses pictures, or icons, to represent files and programs on the screen and allows users to issue commands using input devices.

Input Devices (GUI)

Devices used to issue commands within a GUI, like keyboards and mice or touchscreens.

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.
