What advantage does system virtualization provide in resource management?

System virtualization plays a critical role in resource management by efficiently allocating resources between virtual systems. It allows multiple operating systems to run on a single physical machine, each operating like an independent server. This leads to optimal use of the physical hardware, as resources such as CPU, memory, and storage can be dynamically distributed and managed according to current workloads and demands.

For instance, when one virtual machine is underutilized, the virtual hypervisor can reallocate CPU and memory resources from it to another virtual machine that requires more resources. This ensures that all available hardware is utilized effectively, reducing waste and enhancing system performance. As a result, organizational IT environments can achieve greater flexibility and scalability, allowing for better overall resource management.

This advantage contrasts with the other options, which while they may have merit in certain contexts, do not capture the core benefit of virtualization's impact on resource management as effectively as the efficient allocation of resources does.
