Tag: virtual machine

A virtual machine (VM) is a simulation of a machine (abstract or real) that is usually different from the target machine (where it is being simulated on). Virtual machines may be based on specifications of a hypothetical computer or emulate the architecture and functioning of a real world computer.
A virtual machine (VM) is a software implementation of a machine (i.e. a computer) that executes programs like a physical machine. Virtual machines are separated into two major categories, based on their use and degree of correspondence to any real machine. A system virtual machine provides a complete system platform which supports the execution of a complete operating system (OS) . These usually emulate an existing architecture, and are built with the purpose of providing a platform to run programs where the real hardware is not available for use (for example, executing software on, otherwise, obsolete platforms) or having multiple instances of virtual machines lead to more efficient use…
