WHAT IS 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. The virtual machine typically emulates a physical computing environment, but requests for CPU[->0], memory, hard disk[->1], network and other hardware resources are managed by a virtualization layer which translates these requests to the underlying physical hardware. VMs are created within a virtualization layer, such as a hypervisor[->2] or a virtualization platform that runs on top of a client[->3] or server operating system. This operating system is known as the host OS[->4]. The virtualization layer can be used to create many individual, isolated VM environments.
WHAT IS VMWARE?
VMware Workstation is a hypervisor[->5] that runs on x64[->6] computers; it enables users to set up multiple virtual machines[->7] (VMs) and use them simultaneously along with the actual machine. Each virtual machine can execute its own operating system, such as Microsoft Windows[->8], Linux[->9] or BSD[->10] variants. As such, VMware Workstation allows one physical machine to run multiple operating systems simultaneously. Workstation is developed and sold by VMware, Inc.[->11], a division of EMC Corporation[->12]. VMware Workstation supports bridging[->13] existing host network adapters[->14] and share physical disk drives[->15] and USB[->16] devices with a virtual machine. In addition, it can simulate disk drives. It can mount[->17] an existing ISO image[->18] file into a virtual optical disc...
