Explanation

Type 1 Hypervisor Explained

A Type 1 hypervisor (also called a "bare-metal" hypervisor) runs directly on the physical hardware and contains its own built-in operating system, making option B correct - examples include VMware ESXi, Microsoft Hyper-V, and Xen. Option A describes a Type 2 hypervisor, which also runs on physical hardware but requires a pre-existing OS (like Windows or Linux) to function first - the key distinction being the dependency on an existing OS. Options C and D are incorrect because hypervisors (both Type 1 and Type 2) run on physical servers, not virtual ones - a virtual server is the output of a hypervisor, not where the hypervisor itself lives.

Memory Tip: Think of Type 1 as being #1 - first on the hardware with no OS needed underneath it. Type 2 comes second, needing another OS already installed before it can work. The number reflects the layer position: Type 1 = hardware first, Type 2 = OS first.
