What term refers to software that works on more than one platform?

The term that describes software capable of functioning on multiple platforms is "cross platform." This designation highlights the software's versatility and compatibility across different operating systems or hardware environments, such as Windows, macOS, Linux, and mobile platforms. Cross-platform software allows users to access and utilize the same application regardless of the device they are using, promoting flexibility and broad accessibility.

For instance, a cross-platform application can be developed to run on a desktop computer and also on smartphones, ensuring users have a seamless experience whether they are at home or on the go. This adaptability is particularly valuable in today's diverse technological landscape, where users utilize various devices.

Other choices like database refer specifically to a collection of data organized in a manner that allows for easy access and management, not to compatibility across platforms. Open source describes software with source code that anyone can inspect, modify, or enhance, which does not inherently imply cross-platform capabilities. Proprietary software, on the other hand, is software owned by an individual or company and is typically restricted to specific platforms or systems, which contrasts with the nature of cross-platform software.
