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

• A. Emulation
• B. Blob Storage
• C. Application Virtualization
• D. Key-Value Pair

Answer: (C)

Application virtualization focuses on isolating an application from the underlying operating system by packaging the app with its own runtime environment and dependencies. This virtualized layer sits between the program and the host OS, so the app can run without relying on or conflicting with the system’s installed libraries, registry entries, or specific OS components. That isolation makes deployment easier, prevents compatibility issues between different applications, and allows multiple versions to run on the same machine without disturbing one another. This is different from emulation, which recreates hardware or an entire different operating system to run software not natively supported on the host; emulation is about compatibility at the system level rather than encapsulating a single application's execution. Blob storage and key-value pairs are data storage concepts and do not address how an application is isolated from or interacts with the operating system.
