Explanation:

Virtualization is a technology that allows creating multiple virtual machines (VMs) on a single physical server. Each VM can run its own operating system and applications, and share the resources of the physical server, such as CPU, memory, disk, and network1. Virtualization can help improve server utilization and management in several ways, such as:

• Reducing the number of physical servers needed to run the same workload, which can lower the costs of hardware, power, cooling, and maintenance1.

• Increasing the flexibility and scalability of the server infrastructure, as VMs can be created, deleted, moved, or resized on demand without affecting the other VMs or the physical server1.

• Enhancing the availability and reliability of the server applications, as VMs can be backed up, restored, or migrated to another physical server in case of failure or maintenance1.

• Improving the security and isolation of the server data, as VMs can be configured with different levels of access and protection, and separated from each other and the physical server1.
