1. What is a virtual machine?

The nature of virtual machines: virtual machines are essentially an application software. Like other applications running on Windows, it's just that his function is different.

2. Features of virtual machines

Virtual machine refers to a complete computer that is running in a fully isolated environment with full hardware system functionality that is simulated by software. This means that your computer can have multiple systems at the same time, whether it's a different Windows system, a Linux system, or a Mac OS system.

3. Virtual machine Application (1) enables a computer to have multiple operating systems at the same time.

Many people only know that the computer has a Windows system, but do not know the Linux system, Mac OS system, but as a very curious me, of course, to experience the operation of other systems feel, we need to buy another Mac Apple computer? Do we have to install the Linux system separately? No! No, with the help of virtual machine software, we can enjoy the fun of various operating systems.

(2) You can safely test the virus without threatening your real machine.

We are afraid of the virus, light black screen blue screen, heavy is the crash, when we develop a virus, or the download of things not at ease, you can test in the virtual machine, even poisoning, but also for your computer no harm, as long as the virtual machine to install a system on it.

(3) You can test your own program, which is also the equivalent of running on another computer.

Sometimes, we have developed a small software, but also want to send a friend to try, but found that friends can not use, clearly in their own computer running good, then we naturally want to send a friend, first find another computer test test, virtual machine can provide to you another computer.

(4) An environment where you can build an operating system that fits your needs

When I was learning python, I always felt that the environment was very complex, or that I had too many software installed on my computer, and some software was suppressing each other, which caused the environment to build up easily, so you can build a special environment in the virtual machine without installing the software.

4. Types of Virtual machines:

The following two types of mainstream virtual machines, namely VMware virtual machines and VirtualBox virtual machines, are only a rough introduction in this section, and the following chapters will be described in detail.
