Problems: 1. The computer has a complex stracture (CPU and other diffrent components). 2. small set of primitive commands (changing from one computer to another..)
The operating system is answering these problems by adding a new abstarction layer (it's actually hidding non important or primitive elements).

Operating system as an extended machine?
The Computer being a very complex machine appears to us the users as a very easy to use machine all thanks to the operating system. The operating system hides all the underlying processes that are going on in the computer like interrupt,memory allocation,time pulse etc and presents the user with a more simplified user friendly interface. Because in general sense an ordinary user is not interested in the complicated processes that go on in the computer system.
What the advantage for an operating system designer of using a virtual machine?
A virtual machine will provide generic hardware that can be found in many other computers. Having a virtual machine eliminates the need to have either a second system, or to reboot to test their operating system.
What is tha advantage for an operating system of using a virtual machine?
An advantage of using a virtual machine is you can run multiple operating systems under the umbrella of one operating system. Without a virtual machine you have to reboot every time you want to want to change operating systems but with a VM you can simply switch between them.
How a operating system is related to computer hardware?
The operating system (OS) controls the hardware. A successful computer system will have hardware and an operating system. Application software is not required. All operating systems have a low level, or machine language to run the operation system and control all hardware.
