Desktop virtualization is a technology that allows users to run multiple operating systems and applications on a single physical computer. It creates a virtual environment where each user can access their own desktop, complete with personalized settings and software, regardless of the underlying hardware. This setup enhances flexibility and resource management. By using virtual machines, organizations can streamline IT management, reduce costs, and improve security. Users can access their virtual desktops from various devices, enabling remote work and collaboration. Overall, desktop virtualization simplifies computing while providing a consistent user experience across different platforms.
