Virtual Machines (VMs)

Virtual Machines (VMs) are software-based simulations of physical computers that run an operating system and applications, just like real hardware. VMs use a hypervisor, which is a layer of software that sits between the hardware and the virtual machines. The hypervisor allocates resources such as CPU time, memory, and storage to each VM.

VMs allow multiple operating systems to run on a single physical machine, providing isolation between different environments. This enables more efficient resource utilization, supports testing and development across different OS platforms, and enhances security by isolating workloads. Common uses of VMs include cloud computing, software testing, and running legacy applications on modern hardware.
