Which concept encapsulates computer programs from the underlying OS on which they are executed?

• A. Metadata
• B. Emulation
• C. Application Virtualization
• D. Tag

Answer: (C)

Isolating an application from the host operating system by providing a self-contained runtime is what this is about. Application virtualization packages an app together with the libraries, settings, and components it needs and runs it inside a contained environment on the existing OS. This decouples the program from the specifics of the underlying OS, so the app behaves consistently even if the host system changes or has other software installed. Emulation, while capable of running software designed for another platform by mimicking that platform, isn’t primarily about decoupling the application from the OS. Metadata and tags are just data about data, not mechanisms for separating how software is executed. So the concept that encapsulates computer programs from the underlying OS is application virtualization. Examples include tools like App-V or VMware ThinApp that create these isolated runtimes for applications.
