Which type of virtualization improves portability of applications?

Application virtualization significantly enhances the portability of applications by encapsulating them from the underlying operating system and hardware. This separation allows applications to run in isolated environments, which means they can be transferred and executed on different systems without needing to be reinstalled or reconfigured. As a result, the applications can maintain their settings and dependencies regardless of the host environment, making it easier for organizations to deploy updates across various infrastructures.

In contrast, other types of virtualization, such as network, server, and storage virtualization, serve different purposes. Network virtualization focuses on creating a virtualized network environment, server virtualization allows multiple server instances to run on a single physical server, and storage virtualization combines multiple storage devices into a single virtual storage pool. While these types of virtualization improve resource utilization and management, they do not specifically address the portability of applications.
