Which concept in virtual machines allows multiple operating systems to share the same hardware resources while remaining isolated from each other?

A hypervisor is a software layer that enables multiple virtual machines (VMs) to share the same physical hardware. It allows each VM to run its own operating system while remaining isolated from other VMs on the same host. Hypervisors come in two types: Type 1 (bare metal) runs directly on the hardware, while Type 2 (hosted) runs on top of a host operating system. The hypervisor manages hardware resources like CPU, memory, and storage and allocates them to the VMs, ensuring that each VM operates independently. Why other options are wrong: a) Partitioning : Refers to dividing memory or storage but doesn't manage the entire virtual environment. c) vNIC : Virtual NICs are used to connect VMs to networks but do not manage virtual machines or isolation. d) Containerization : Containerization is similar to virtualization but focuses on packaging applications and their dependencies without creating full VMs. e) Snapshotting : Snapshotting creates backups of VM states but doesn’t handle the execution or isolation of virtual machines.
