Understanding the Security Features of VMware Virtual Machines

A virtual machine (VM) is a software-based emulation of a physical computer that operates as if it were a separate physical machine. It runs on a physical computer and can run its own operating system and applications as if it were a physical computer. Virtual machines are often used for testing software in a controlled environment, running multiple operating systems on a single physical machine, or creating isolated environments for security purposes. They are also commonly used in cloud computing environments to provide scalability and flexibility for running applications.
