A hypervisor, also known as a virtual machine monitor (VMM), is a layer of software, firmware, or hardware that creates and manages virtual machines (VMs). It allows multiple operating systems to run concurrently on a single physical computer. The hypervisor intercepts and manages the requests from the virtual machines to the underlying hardware, ensuring that each VM operates independently and has its own dedicated resources such as CPU, memory, and storage.

There are two main types of hypervisors: Type 1 and Type 2. Type 1 hypervisors, also called bare-metal hypervisors, run directly on the host's hardware without an underlying operating system. Examples include VMware ESXi, Microsoft Hyper-V, and Xen. This architecture offers better performance and security as there is no host operating system layer to compromise. Type 2 hypervisors, also known as hosted hypervisors, run as an application on top of a conventional operating system, such as Windows, macOS, or Linux. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop. These are generally easier to set up and use but may have slightly lower performance due to the overhead of the host OS.

Hypervisors are crucial for cloud computing, server consolidation, testing and development environments, and disaster recovery solutions. They enable efficient utilization of hardware resources, provide isolation between different workloads, and facilitate flexible deployment and management of computing resources.
