MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A Type 1 hypervisor runs directly on the host computer’s physical hardware. These hypervisors are typically faster and more efficient than Type 2 hypervisors, as they: Interact directly with the host computer’s CPU, RAM, and physical storage space. Bypass the need to go through the OS layer.

Detailed explanation-2: -Type 1 or bare-metal hypervisor is a virtualization software used to create virtual machines on top of the computer hardware. Direct hardware installation allows Type 1 hypervisors to be fast, efficient, and have better security when compared to a Type 2 hypervisor.

Detailed explanation-3: -Pros: Type 1 hypervisors are highly efficient because they have direct access to physical hardware. This also increases their security, because there is nothing in between them and the CPU that an attacker could compromise.

Detailed explanation-4: -The main difference between Type 1 and Type 2 Hypervisor is that Type 1 Hypervisor runs directly on the host’s hardware while Type 2 Hypervisor runs on an operating system similar to other computer programs. Running applications on individual systems cause resource wastage.

Detailed explanation-5: -Bare metal hypervisors are faster and more efficient as they do not need to go through the operating system and other layers that usually make hosted hypervisors slower. Type I hypervisors are also more secure than type II hypervisors.
