What is a virtual machine What is the use of a virtual machine?

The virtual machine uses a computer to allocate multiple areas with complete computer characteristics. Each virtual area does not affect each other. The virtual machine plays a big role in our lives. It is widely used by computer enthusiasts and enterprises. The following article will share with you what is the role of virtual machines and virtual machines, and hope to learn from the majority of computer enthusiasts, this is also the knowledge that Computer Pepsi.com is happy to share with you.

What is a virtual machine?

The terminology is defined as follows: Virtual Machine (English name: Virtual Machine) is a complete computer system that runs through a software and has a complete hardware system function and runs in a completely isolated environment. The virtual machine software includes VMware (VMWare ACE), Virtual Box, and Virtual PC, all of which can virtualize multiple computers on a Windows system. Each virtual computer can run independently and can install various software and applications.

Generally speaking, a virtual machine is a function of virtualizing a computer to implement a computer with multiple computers, but the performance of the whole machine is also allocated by each virtual machine, so The more virtual machines, the less CPU, memory, and storage resources are allocated to each virtual machine. Therefore, the virtual machine is usually configured as high as possible, so it is widely used in servers and other industries.

What is the use of virtual machines? The role of the virtual machine in reality is still quite large. For example, the simplest one is that there is no optical drive in our computer. If you want to install the system, we can use the virtual machine to install the system. The virtual machine has a virtual optical drive inside, and it can directly open the system image file installation system. In addition, virtual machine technology is also very useful in the eyes of game lovers. For example, we know that many games in a computer do not support multiple games at the same time, but we can create more virtual machines in the computer, then in the virtual machine system. The program can be run separately, so that one computer can open the same game at the same time. In addition, there are many functions of virtual machines, which are not introduced here.

In fact, virtual machines are widely used in enterprises. Because servers are usually configured very high, many server network operators usually divide one server into multiple virtual machine servers in order to meet the needs of small and medium-sized webmasters. Each website can allocate a part of independent server resources, and does not affect each other and can be equipped with independent IP addresses, which greatly solves the problem that the cost of using separate servers for SMEs is too high. Currently, the VPS servers purchased are all using this technology. The virtual space used by friends in the beginning is also the principle. Interested friends may wish to understand.
