Virtual Machines: A Cost-Effective Solution for IT Development and Testing

Virtual machines are software-based emulations of physical computers that can run applications and operating systems just like a physical machine. They allow users to create multiple virtual environments on a single physical machine, enabling them to run multiple operating systems and applications simultaneously. Virtual machines are commonly used for testing software compatibility, running multiple operating systems on a single computer, and for server virtualization in data centers. They offer benefits such as cost savings, flexibility, and improved resource utilization.
