Network Administration - The virtual machine allows you to run different operating systems with the current operating system. The operating system will operate as if the computer program. The virtual machine is ideal for testing the operating system, such as new versions of Windows 8 or the Linux operating system. You can also use virtual machines to run the software on operating systems that they are not compatible, such as one can run Windows programs on Mac virtual machine.
On the other hand, users may not pay any cost because there are some free virtual machine program is great to experience.
What is virtual machine?
A virtual machine is a program that acts as a virtual computer. It runs on the current operating system - the host operating system and provides virtual hardware to the guest operating system. The guest operating system running on the windows of the host operating system, like any other program of the machine. For guest operating systems, virtual machines to present as a real physical machine.
Virtual machines provide hardware virtualization, including virtual CPU, virtual memory, hard drives, network interfaces and other devices. The virtual hardware provided by the virtual machine and is mapped to the real hardware on the computer. For example, virtual hard drive files can be saved in a file located on the hard drive.
You can install multiple virtual machines to real machines and only limited by the amount of storage available to them. Once you've installed a few operating systems, you can open the virtual machine and select the program you want to boot the virtual machine, boot the guest operating system and run in a window or the host operating system can run in full screen (full-screen mode).

The effects of virtual machines
Virtual machines have some common effects:
Test versions of operating systems: You can run a test version of Windows 8 virtual machine running Windows 7. This allows you to test Windows 8 without having to install an unstable version of Windows on their machines.
Testing of other operating systems: You can install many different Linux distributions and operating systems less known than in a virtual machine to test them and find out how they work. If you are interested in Ubuntu, you can install it on virtual machine and use in a window on the desktop normally.
program window
Using the software requires an older operating system: If you have an important application that only runs on Windows XP, you can install XP on a virtual machine and run applications on virtual machines. Virtual machines are actually running Windows XP, so compatibility is not an issue. This allows the user to use an application that is only compatible with Windows XP without having to install Windows XP on it, especially important when considering the many new laptops and other hardware without full support for Windows XP .
Running software designed for other operating systems: Mac and Linux users can run Windows on a virtual machine to use the software for Windows on your computer without compatibility headaches. Unfortunately, the game then this might be a problem. The virtual machine program latency and not a virtual machine application that allows to run the latest 3D games. Some 3D effects supported, but is less 3D graphics are supported on virtual machines.
Software testing on multiple platforms: If you need to test an application that is compatible with multiple operating systems or different versions of Windows or not, you can install each OS on a virtual machine instead of a lever multiple machines carried around.
Spice up a server: For enterprises using multiple servers, the server can be placed on the virtual machine and run on a single machine. Each virtual machine is a quarantine folder, so this does not cause security risks associated with running multiple servers with different operating systems. Virtual machines can be moved between the real server.
Virtual machine software
VirtualBox is an application open source virtual machine runs great on Windows, Mac OS X and Linux. One of the best things about VirtualBox is not a commercial version. You get full functionality for free, including advanced features such as "snapshots", which allows to save virtual machine state.

VMware Player is a program virtual machines and other quality for Windows and Linux. VMware Player is a free copy of VMware Workstation, a commercial application, so you will not get full advanced features such as with VirtualBox. However, both VirtualBox and VMware Player are trusted program, providing basic features for creating virtual machines that run free.

To install an operating system on a virtual machine, you need the installation disk or operating system can use ISO image file extension that the Linux distributions usually provide for download. The virtual machine program offers a friendly interface easy to create a virtual machine and install operating system.
You can also download virtual machines were created and installed the OS from another virtual machine and the load on the virtual machine program to launch it. To download the image file was made available to the virtual machine, visit the website VirtualBoxes.
