hypervisors
A hypervisor is a software layer that allows multiple operating systems to run on a single physical machine. It creates and manages virtual machines (VMs), enabling each VM to operate independently as if it were a separate computer. This technology is essential for efficient resource utilization and is commonly used in data centers and cloud computing.
There are two main types of hypervisors: Type 1, or bare-metal hypervisors, run directly on the hardware, while Type 2, or hosted hypervisors, run on top of an existing operating system. Popular examples of hypervisors include VMware, Microsoft Hyper-V, and Oracle VirtualBox.
