Virtualization software enables the creation and execution of multiple virtual machines (VMs) on a single physical machine. Each VM acts as an independent system, featuring its own OS, applications, and resources, despite the shared hardware. This technology is widely used for software testing, development, server consolidation, and running multiple OS environments without the need for separate physical machines.

One of the most popular virtualization solutions is Oracle VM VirtualBox, a free, open-source tool that supports a wide range of guest operating systems. In this article, we’ll explore what Oracle VM VirtualBox is, its applications and key features, and step-by-step installation guides for Windows and Ubuntu.
