QEMU is a free open source program that emulates various hardware platforms. But this program can't be used for virtualization on macOS. VMware Workstation is a powerful, paid, and the most reliable program for virtualization, that supports Windows and Linux OS. VirtualBox allows you to install almost any current operating system as a "guest" one, whether it be Windows, macOS or any of the numerous representatives of the Linux family.

VirtualBox is a very simple, powerful and free tool for virtualization, developed with the support of the famous Oracle Corporation. Oracle VirtualBox - a universal free virtual machine. The list of operating systems which can be installed on virtual machines, varies greatly and depends on the particular virtualization system. A virtual machine allows you to install and run multiple guest systems (OS, running on virtual machines) within a single host system (OS, installed on the hardware) at the same time. And if the operating system is not a free one, you will have to buy it.Ī virtual machine is software that emulates the work of a hardware platform with all its components (a processor, memory, a hard drive, USB, optical drive, video and network adapters, etc.). There is a number of specialized software products that enable you to install a virtual guest 64-bit OS, where you will be able to install and run the required application. But in the future this difference will become more prominent due to the RAM usage increase, and further technological development.įor the family of Linux operating systems, and the 32-bit Windows OS, virtualization technology is used to run 64-bit applications in a 32-bit environment. So at this moment there is absolutely no difference between loading in 32 and 64-bit modes. The only difference between a hybrid core and a full 64-bit one is the inability to use more than 32 GB of RAM in the system. It allows the running of any application regardless of its bit rate. Let's take a look at some of the most popular OS. Also, to support 64-bit applications your processor should have a 64-bit architecture. Firstly, starting 64-bit applications in the 32-bit environment you lose the benefit of using more RAM. There are certain peculiarities in different operation systems, related to the 64-bit applications launch in the 32-bit environment.

So what shall the user do if he/she is not ready to stop using the 32-bit OS as the main working system? A lot of modern program tools are developed to be run only in 64-bit mode, because the maintenance of both 32 and 64 bit operating systems requires additional expenses.įor the users of 32-bit OS, it is sometimes necessary to use software designed only for 64-bit OS. But 32-bit OS are still present on the market, in quite obvious quantities.

Nowadays 64-bit operating systems are very widespread.
