Computer Studies VirtualboxOracle's VirtualBox is basically a software program that allows you to install an operating system in a virtual PC environment, emulating a computer on your host computer; you can use the guest operating systems as you would normally as if they were installed directly on your PCs hard drive.

With VirtualBox you can run more than one operating system at a time. This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it. Software manufactures use this program for testing beta versions of their products before general release on many different operating systems.

You can use a VirtualBox feature called "snapshots", saving a particular state of a virtual machine and then reverting back to that state, if necessary. This way, you can freely experiment with a computing environment. If something goes wrong with an operating system such as it getting infected with a virus, you can easily switch back to a previous snapshot and avoid the need of frequent backups and restores.

Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time, making this program great for trying out any ideas for troubleshooting problems with the various operating systems without having to alter your host PC (and best of all it's a free open source program, so it won't cost you anything to install)

Computer Studies Virtualbox

Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and innotek VirtualBox) is an x86 virtualization software package, created by software company Innotek GmbH, purchased by Sun Microsystems, and now developed by Oracle Corporation as part of its family of virtualization products. Oracle VM VirtualBox is installed on an existing host operating system as an application; this host application allows additional guest operating systems, each known as a Guest OS, to be loaded and run, each with its own virtual environment.

Supported host operating systems include Linux, Mac OS X, Windows XP, Windows Vista, Windows 7, Windows 8, Solaris, and OpenSolaris; there is also a port to FreeBSD. Supported guest operating systems include versions and derivations of Windows, Linux, BSD, OS/2, Solaris and others. Since release 3.2.0, VirtualBox also allows limited virtualization of Mac OS X guests on Apple hardware, though OSX86 can also be installed using VirtualBox Since version 4.1, Windows guests on supported hardware can take advantage of the recently implemented WDDM driver included in the guest additions; this allows Windows Aero to be enabled along with Direct3D support.
