What vital role does a hypervisor play in computing?

A hypervisor plays a crucial role in enabling virtualization, which allows multiple operating systems to coexist on a single physical machine. This functionality is fundamental to cloud computing and server management, as it permits efficient use of hardware resources. The hypervisor manages the virtual machines (VMs), ensuring that they share the physical resources of the host machine without interfering with one another. This segregation provides not just efficiency but also enhances security and isolation between different operating systems.

The ability to run various operating systems concurrently on the same hardware allows organizations to maximize their resource utilization, reduce hardware costs, and simplify system management. This is particularly important for testing and development environments, where different operating systems may need to be evaluated without the need for separate physical machines. Overall, the hypervisor is integral to modern computing environments, particularly in data centers and cloud infrastructure.
