15. SYSTEM SOFTWARE
Operating System
 acts as an interface between user and hardware
 controls all computer resources
 required for using other software
 software that controls hardware

16. OBJECTIVES OF OS
 hide details of hardware
 manage resources
 provide a user interface
Examples of OS
 DOS (Character User Interface)
 Windows (Graphical User Interface)
 Android (Mobile Operating System)

17. APPLICATION SOFTWARE
Application Software
 designed to complete a specific task such as painting,
financial accounting, writing letters etc.
