Host refers to the computer you will be running VirtualBox on your computer’s native OS. Two terms you need to learn right away to be able to work with VirtualBox are host and guest. At an enterprise level, rather than running a backup server, a separate mail server, and a separate SharePoint server, each can run in its own virtual instance on a single physical host machine. So rather than building a separate computer to run a different operating system, you only need one. It allows individuals and enterprises to run several functions on a single computer, rather than forcing someone to find the space and the money to have more than one.

VirtualBox doesn’t care what you use as long as you configure it properly. We can also use different versions of Linux within Linux or Windows within Windows. If you're looking for a free solution to virtualize almost any operating system on the market, try out VirtualBox.You could run Linux within Windows or the other way round. It has a system called RDP (Remote Desktop Protocol), with which the machine will be able to perform like a server so that we can access the system remotely from any client, as if it were a VNC system.

How it works is rather simple compared to other similar applications, because it's only necessary to select the resources that the virtual machine will be able to use (RAM memory, hard drive space, CPU power, network connection.). VirtualBox is a virtualization software application that is compatible with the AMD64/Inter64 and x86 architectures that offers us the opportunity to easily install Windows, GNU/Linux, Mac OS X and Solaris operating systems. Try out any operating system on your Mac. Nowadays, tools like Parallels Desktop or VMware Fusion are very popular among users, but there are also free alternatives like VirtualBox. The use of virtual machines can be very practical if we need to test an operating system or launch applications that may make our computer unstable.
