Answer:
In computing, a virtual machine (VM) is an emulation( an emulator is hardware or software that enables one computer system (called the host) to behave like another computer system (called the guest))of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their features may involve specialized hardware, software, or a combination of both.
There are different kinds of virtual machines, each with different functions:
1.System virtual machines (also termed full virtualization VMs) provide a substitute for a real machine. They provide what is needed to execute entire operating systems.
2.Process virtual machines are designed to execute computer programs in a platform-independent environment.
