Final answer:
There are two types of hypervisors: Type 1 and Type 2. Option A is correct.
Step-by-step explanation:
The correct answer is A) two. There are two types of hypervisors: Type 1 and Type 2 hypervisors.
Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the host's hardware. They do not require an underlying operating system. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and KVM.
Type 2 hypervisors, also known as hosted hypervisors, run on top of an existing operating system. They require another operating system between the hypervisor and the host. Examples of Type 2 hypervisors include Oracle VirtualBox and VMware Workstation.
There are two types of hypervisors, distinguished by whether there is another operating system between the hypervisor and the host. The first type is called a Type 1 or bare-metal hypervisor, which runs directly on the host's hardware to control the hardware and to manage guest operating systems. The second type is known as a Type 2 or hosted hypervisor, which runs on a conventional operating system just like other computer programs.
