VirtualBox

VirtualBox is a free and open-source hypervisor for x86 virtualization, developed by Oracle. It allows users to create and run multiple virtual machines (VMs) on a single physical host, each with its own guest operating system, enabling software testing, development, and cross-platform compatibility without needing separate hardware.

Also known as: Oracle VM VirtualBox, Virtual Box, VBox, Oracle VirtualBox, VirtualBox VM

Why learn VirtualBox?

Developers should learn VirtualBox for creating isolated development environments, testing applications across different operating systems (e.g., Linux, Windows, macOS), and safely experimenting with new software or configurations without risking the host system. It's particularly useful for DevOps, QA testing, and learning system administration skills in a sandboxed setup.
