Which of the following best describes a Type 1 Hypervisor?

A Type 1 Hypervisor, often referred to as a native or bare-metal hypervisor, operates directly on the physical hardware of a host system. This architecture allows it to manage guest virtual machines without needing an underlying operating system, which differentiates it from a Type 2 Hypervisor that runs on top of a host OS. By interacting directly with the hardware, a Type 1 Hypervisor generally provides better performance, scalability, and efficiency compared to its Type 2 counterpart.

In the context of virtualization, this characteristic allows for more effective resource management as it can allocate hardware resources like CPU, memory, and disk space directly to the virtual machines. Such direct interaction with hardware also typically results in improved system stability and security, since there is no additional layer of the host operating system that could introduce vulnerabilities or performance bottlenecks. Therefore, option B accurately captures the essence of a Type 1 Hypervisor.
