User and Operating System Interface

Presented User and Operating System Interface for my Operating System Course

1. User and Operating-System Interface By Nusrat Jahan Shanta

2. How do Users interact with the Operating System?

3. The interface could be:                                     - Command Interpreters                                     - A Graphical User Interface                                     - Non-interactive batch system

4. Command Interpreters

5. Command Interpreters User-Specified Commands

6. Command Interpreters Two Approaches to Implement Commands: 1. It itself contains the code To Execute Command. 2. Implements command through System programs.(used by UNIX)

7. Command Interpreter The UNIX command to delete a file(2nd Approach): rm file.txt Advantages in this Approach: - Add new commands - size of the program is small

8. Graphical User Interfaces ON Desktop: a mouse-based windows and menu system as an interface. On Smartphone:  A touch Screen Interface.
