Hypervisors, also known as Virtual Machine Monitors (VMMs), are software, firmware, or hardware that creates and runs virtual machines. They allow a single host computer to run multiple guest operating systems simultaneously. Each virtual machine operates independently, with its own virtualized hardware resources such as CPU, memory, storage, and network interfaces. This isolation ensures that if one guest operating system crashes, it does not affect the others or the host.

There are two main types of hypervisors. 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. They are typically used in enterprise data centers and cloud computing environments due to their performance and security advantages. Type 2 hypervisors, also known as hosted hypervisors, run on a conventional operating system as an application. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop. These are commonly used on personal computers for development, testing, or running different operating systems alongside the primary one.

Hypervisors are fundamental to virtualization technology, enabling efficient resource utilization, improved disaster recovery, faster deployment of new systems, and a flexible environment for software development and testing. They abstract the physical hardware, presenting virtualized hardware to each guest OS, allowing for a variety of operating systems and applications to coexist on a single physical machine.
