A virtual machine (VM) is like a computer inside another computer. It's a software program that acts like a real computer, with its own CPU, memory, and storage. You can install an operating system and applications on it, just like you would on a physical computer.
VMs are useful for many reasons, such as:
- Running multiple operating systems on one computer: You can use a VM to run Windows on a Mac, or vice versa.
- Testing software safely: You can use a VM to test software without risking harming your main computer.
- Creating isolated environments: You can use a VM to create a safe environment for sensitive data or applications.
