Detailed explanation-1: -Option-All of the above is the correct answer. Explanation: A virtual machine, abbreviated as VM, is similar to any other physical computer, such as a laptop, smartphone, or server. It features a CPU, RAM, and discs for storing your files, as well as the ability to connect to the internet if necessary.
Detailed explanation-2: -A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.
Detailed explanation-3: -A virtual machine (VM) is a computer system emulation that behaves like a computer but does not need its own separate hardware in order to function. A VM is referred to as a guest of the computing environment where it is installed, which is known as the host.
Detailed explanation-4: -Virtual machine file system VMFS provides on-disk distributed locking to ensure that the same VM is not powered on by multiple servers at the same time. If a physical server fails, the on-disk lock for each VM is released so that VMs can be restarted on other physical servers.
