The principle of VirtualBox:
VirtualBox virtual system has exactly the same function as the real windows system by generating a brand-new virtual image of the existing operating system. After entering the virtual system, all operations are carried out in this brand-new independent virtual system. You can install and run software independently, save data, have your own independent desktop, and have no impact on the real system. There is an operating system that can be flexibly switched between the existing system and the virtual image.
Virtual system will not reduce the performance of the computer, and it will not take too much time to start the virtual system as it does to start the windows system, so it is more convenient and faster to run the program. Virtual system can only simulate the same environment as the existing operating system, while virtual machine can simulate other kinds of operating systems; Moreover, the virtual machine needs to simulate the underlying hardware instructions, so the running speed of the application is much slower than that of the virtual system.
