Virtuaalmasinanid, often referred to as virtual machines or VMs, are software-based emulations of a physical computer. They allow a user to run an operating system and its applications on top of another operating system, essentially creating a computer within a computer. This is achieved through a piece of software called a hypervisor, which manages the allocation of the host machine's physical resources, such as CPU, memory, and storage, to the virtual machine.

The primary benefit of virtual machines is their flexibility and isolation. Multiple virtual machines can run concurrently on a single physical machine, each with its own operating system and environment, without interfering with each other. This is invaluable for software development and testing, allowing developers to create and test applications in various operating systems and configurations without needing multiple physical machines.

Virtualization also enhances security by isolating potentially risky applications or unknown software within a VM. If the VM becomes compromised, the host system remains unaffected. Furthermore, VMs simplify disaster recovery and business continuity. Snapshots can be taken of a VM's state, allowing for quick restoration in case of data loss or system failure. They are also used extensively in cloud computing, where providers offer virtualized resources to customers.
