VirtualBox

VirtualBox is a software application that allows you to run multiple operating systems (like Windows, Linux, or macOS) on a single computer simultaneously. It creates virtual machines—software-based computers—that operate independently within your existing system. This enables you to test, develop, or use different environments without affecting your main system. VirtualBox manages these virtual machines efficiently, providing tools to allocate resources such as CPU, memory, and storage, making it a versatile solution for experimentation, software testing, and learning about various operating systems without needing additional physical hardware.
