Figure 1: The Operating System in a Hierarchy

But an applications software package does not communicate directly with the hardware. As shown in Figure 1, between the applications software and the hardware is a software interface - an operating system

Answer 2

Explanation:

2. Establish a user interface
3. execute and provide services for applications software.Thus you both establish a user interface and execute software.
