Hello everyone, Lin Fei to answer the above questions for everyone, virtual machine is what means how to play, virtual machine is what many people do not know, now let us take a look!

Virtual Machine (English full name: Virtual Machine) refers to a complete computer system simulated by software, with complete hardware system functions, running in a completely isolated environment. At present, the more popular virtual machine software are VMware(VMWare ACE, Virtual Box, Virtual PC), which can create multiple computers on Windows system, each virtual machine can run independently, install various software and applications.

Generally speaking, virtual machines virtualize a computer to realize the function of one computer having multiple computers, but the performance of the whole machine will also be divided by each virtual machine. Therefore, the more virtual machines are partitioned, the less CPU, memory, and storage space resources are allocated per virtual machine. Therefore, the higher the configuration, the better, so it is widely used in industries such as servers.

Virtual machines play a very important role in reality. For example, in the simplest case, we don't have an optical drive in our computer. If we want to install the system, we can use virtual machines to install the system. There is a virtual optical drive inside the virtual machine, which supports directly opening the system image file to install the system. In addition, virtual machine technology is also quite practical in the eyes of game enthusiasts and friends. For example, in general, many games in a computer do not support playing multiple games at the same time, but we can create several virtual machines in the computer, and then run programs in the virtual machine system, so that a computer can play

In fact, virtual machines are widely used in enterprises, because servers are usually highly configured, because many server network providers usually divide a server into multiple virtual machines to meet the needs of small and medium-sized webmasters, so that each website can allocate a part of independent server resources, and can be equipped with independent IP addresses, which do not affect each other, greatly solving the problem of high cost for small and medium-sized enterprises to use separate servers. Currently purchased VPS servers are using this technology, just started to do the website friends use virtual space is also this principle.
