Which term describes the ability of an application to function across different computing environments?

The term that describes the ability of an application to function across different computing environments is portability. Portability refers to how easily software can be transferred and run on various platforms without modifications. For instance, a portable application can operate effectively whether it's on a Windows, macOS, or Linux system, indicating that the developers have written the code in a way that accommodates multiple operating systems and hardware configurations.

Understanding portability is crucial in software development, especially when considering diverse user environments, as it ensures broader accessibility and usability of applications. This flexibility allows users to switch between devices or operating systems without losing functionality, which is increasingly important in a world with a variety of computing devices.
