What is a system virtualization?

usually the virtualization of the system concerns one of the two things; Virtualization of a computer system virtualization or operating system virtualization. Computer virtualization focuses on using software to create a virtual computer system. The virtualization of the operating system creates a virtual instance of the operating environment. These instances often run on top of other systems or export to a virtual computer system. In both cases, technology focuses on creating a software that emulates the hardware computer system.

virtualization technology has existed since the age of 60. In the first days of computer, software used software to imitate machines and create low -level sources such as memory. These early virtual programs were limited by the relatively low power of computers of this era. Only at the end of the 90's. Increasing computing power, access to high -speed data transmission and widespread use of processors with multiple termsIt was a complete virtual system system to become a reality.

Virtual computer system can be anything from server to desktop workstation. In any form, the computer system works in a similar way - a single hardware computer starts a program that efficiently distributes the system into multiple parts. Each part has a fully functional operating system installed or practically connected to it. The overall program oversees each of the individual parts, but outside each part acts as an independent machine.

What happens then depends on the purpose of the virtualized machine. The virtual server works just like a normal server. Other computers and systems are connected to this, often without knowing that the system is not "real". The virtual desktop system is usually connected to a remote workstation, which is specially equipped for processing virtual workspace.

The

virtualization of the operating system includes virtual servers or desktop computers that connect to one version of the operating system and create a virtual copy at the top of the virtual program. In this case, the user would sit on the station and join the virtual server, which would then connect to the virtual version of the operating system and send it to the user. Another common reason for the virtualization of the operating system is hosting the environment. When the computer acts as an internet host, it contains accounts of many users in one system. Each of these users requires full access to systems provided by the operating system, but not to the sources of other accounts - by creating a virtual operating system for the system as a whole, accounts can approach what they need without disrupting other accounts.
