User Interaction and OS Flashcards
How do applications and the operating system interact with user input?
Applications take user input from actions like typing or clicking and relay it to the operating system, which uses computer hardware to execute the requests.
Define “user interface.”
The user interface is a program that accepts user input, forwards it to the operating system for execution, and presents the results back to the user. It can be a command-line prompt or a graphical user interface (GUI).
What is the role of the operating system in hardware interaction?
The operating system interacts with different types of computer hardware to carry out tasks. It requires device driver software for each hardware device to instruct the operating system on device usage.
What is the function of device driver software?
Each device driver tells the operating system how to use a specific hardware device. This ensures the operating system can effectively utilize all hardware components.
What does the user interface of an operating system include?
The user interface can be a command-line prompt or a graphical user interface (GUI). GUI includes menus, dialog boxes, and icons for user interaction via keyboard or mouse.
