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.
What is process migration in Operating Systems?
It is the transfer of sufficient amount of the state of process from one machine to the target machine.
What is a Guest Operating System?
A Guest operating system is one that runs on top of another, similar to a program. Guest operating systems are usually run in a "virtual machine", which does not interact directly with the real hardware of the computer.
Advantages of network operating systems?
When you network operating systems you will have the benefit of both operating systems. You have to ensure both systems are compatible before networking them.
What is an Operating System designed to run an entire machine from a optical disc without using the systems hard drive called?
Playstation
What is basic bare machine in operating system?
Basic Machine, in computer parlance, means a computer without its operating system. Modern operating systems evolved through various stages, from elementary to the present day complex, highly sensitive real-time systems. In the very first stage of computing there was nothing like an Operating System at all. Programs were fed to the computer system directly using machine language by the programmers without any system software support. This approach is termed the "Bare Machine" approach in the development of operating systems.

Where can one find bare metal?
Bare metal can refer to many things, one being a computer machine that can run without an operating system. One is able to find bare metal in computer shops such as Fry's Electronics.
How DOS and other operating systems work on same machine?
You can use different OS in the same machine.. Its called the Dual Boot..
What Operating Systems include the Java Virtual Machine?
Windows, Solaris, Linux, & Apple OSX...
Can you have two operating systems on one computer?
Yes, but only one can be in control of the system. When a choice of operating systems exist, you typically choose the controlling operating system via a boot menu at startup. To switch to another operating system, you must restart the system. It is possible to run two or more operating systems at the same time via virtual machines. A virtual machine is a software program that emulates a real computer. However, operating systems within a virtual machine have no direct control over the physical machine which is always under the direct control of the one operating system chosen at startup. Virtual machine operating system calls are routed to the virtual machine software which must translate the call to invoke the appropriate system function of controlling operating system. As a result, virtual machines perform extremely poorly compared to the physical machines within which they operate.
In addition to personal operating systems and server operating systems there are also mobile operating systems and?
Virtual operating system
Why do modern machines consist of multiple levels of virtual machines?
Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture
Is there any software to open two open two operating systems at the same time?
Yes. It is called a Virtual Machine.
