with an Operating System (i.e. os ) virtualization software we can run an os inside another os like a program.this concept not only sounds interesting but also provides us with various real life advantages. besides it also finds good use in the industry.[for information : our main operating system is called the 'Host OS' while the os which we run inside our main os with the os-virtualization-software is called 'Guest OS'].so lets see at a glance what advantages it has for us the domestic users:

• allows us gain hands-on-experience on various operating system without any worry of partitioning or formatting our hard disks.
• we can install and experiment with applications without any worry in the guest operating system as the host or native operating system of our computer will remain out of trouble.
• we can study n make changes in the system files of the operating system
• we (i.e. developers ) often develop projects which are not portable or are hard to demonstrate on other computers. as running complex projects requires installation of requisite software and a lot of configurations. these problems can be avoided with os virtualization softwares. we can develop our projects in the virtual os and later carry the entire os [with installed apps. and projects ] to other computers.all we have to do its to install the os virtualization in the target computer
