    1

    What is a virtual machine?

    ~15s
    A virtual machine (VM) is a computer simulated entirely in software. It runs inside a window on your real computer. You can run Windows inside a Mac, or Linux inside Windows — without changing anything on your real system.

    Why use a VM?

    ~15s
    Test software safely before installing on your main system. Try Linux without committing. Run Windows apps on a Mac. Learn IT skills in a safe sandbox. If a VM gets infected with malware, your real computer is unaffected.

    Free VM software

    ~15s
    VirtualBox (free, all platforms): virtualbox.org. Good for running Linux or older Windows. UTM (free, Mac/Apple Silicon): mac.getutm.app. Built-in on Windows: Hyper-V (Pro edition) or WSL for Linux.

    Hardware requirements

    ~15s
    You need a reasonably modern computer with at least 8 GB RAM (16 GB recommended). The VM will share your computer's resources. VMs run slower than native — that's expected.

    Getting started

    ~15s
    Download VirtualBox. Download a Linux ISO (Ubuntu is beginner-friendly). Create a new VM in VirtualBox, point it to the ISO, and follow the installation. You now have Linux running inside a window.

    Practical uses for beginners

    ~15s
    The most practical beginner use: try Ubuntu Linux risk-free. Run old software that doesn't work on new operating systems. Create a safe browsing environment for risky websites.
