The Rise of Virtual Machines: A Game-Changer for Operating Systems


A virtual machine (VM) is a software-based emulation of a physical computer system. It allows multiple operating systems to run on a single physical machine, allowing users to run different applications and software that may not be compatible with their host operating system.

VMs are typically used for testing software on different operating systems, running legacy applications that may not be supported on newer systems, and for creating isolated environments for running potentially harmful or malicious software.

VMs are created using virtualization software, which allocates resources from the host machine to the virtual machine, including CPU, memory, storage, and network resources. VMs can be easily created, duplicated, and deleted, making them a flexible and efficient solution for many computing needs.
