The ability of software to be used on different systems without modification is known as:

Flexibility
Portability
Usability
Testability

The correct answer is: Portability

Portability refers to the quality of software that allows it to function on various hardware and operating systems without requiring alterations to its code. This characteristic is crucial in today's diverse computing environments, where software may need to operate across various platforms and devices. Software that is designed with portability in mind can be easily moved and deployed across different environments, which is essential for maximizing usability and user access. By ensuring that an application or system can run on different platforms without modification, developers can reach a broader audience and significantly enhance the software's usability in different contexts. Other terms, such as flexibility, usability, and testability, relate to different aspects of software characteristics but do not specifically address the capability of software to operate across different environments without modification. Flexibility might refer to the adaptability of software features, usability is concerned with the ease of use for the end-user, and testability involves how easily software can be tested for defects. Therefore, portability is the most accurate term for this context.
