Final answer:
True, a virtual machine can be powered on like a physical server and utilized similarly, allowing efficient hardware utilization and resource distribution through hypervisors.
Step-by-step explanation:
True: Once a virtual machine (VM) is created, it can indeed be powered on similarly to a physical server. After powering on, it can be used in the same ways as a physical server, hosting applications, websites, databases, and more. VMs offer a layer of abstraction over the underlying physical hardware, enabling one physical server to host multiple virtual ones, each with its own operating system and set of programs.
Virtual machines are a cornerstone of modern computing, particularly in data centers and cloud computing environments, because they allow for efficient hardware utilization, isolation, and scalability. They are managed using software called a hypervisor, which is responsible for distributing hardware resources such as CPU time, memory, and storage to each VM as needed. Examples of popular hypervisors include VMware vSphere, Microsoft Hyper-V, and the open-source KVM.
