Virtualization

Virtualization:

Virtualization is extending the computer so that it can run multiple os. For eg: We can run Linux on our Windows machine.

Uses of Virtualization:

one can run software written for one operating system on another(Even if the the real computer hardware is no longer supported by the virtual os)

After installation the virtual box is act as container, we can copy transport and back up between hosts.


One can save a particualr state and revert back.

It reduce the hardware and electricity costs.
