Oracle VirtualBox

Oracle VirtualBox is free software that allows you to run multiple operating systems on a single computer simultaneously. Think of it as creating separate "virtual computers" inside your existing machine. For example, you can run Windows inside a Mac or Linux environment without needing additional hardware. VirtualBox provides an environment where each virtual machine operates independently, sharing resources like memory and storage. It is useful for testing software, running different operating systems, or isolating specific tasks securely, all without altering your main system setup.
