What term describes the ability of systems to exchange data or services?

The term that best describes the ability of systems to exchange data or services is "interoperability." This means that different systems, applications, or services can work together and understand the data they exchange. Interoperability is crucial in environments where multiple systems need to collaborate and share information effectively to perform coordinated tasks.

In practical terms, interoperability ensures that information from one system can be understood and utilized by another without extensive modifications or the need for human intervention. This capability is especially important in sectors like healthcare, finance, and information technology, where seamless data exchange can lead to improved efficiency and better decision-making.

While integration refers to combining different systems into a single unified system, it does not inherently imply that those systems can communicate or work together effectively. Interconnectivity focuses more on the physical or network connections between systems rather than their ability to work together. Compatibility usually denotes the ability of software or hardware to work together without issues, but it doesn't specifically capture the notion of exchange and interaction across various types of systems and services. Thus, "interoperability" is the most precise term for the ability of systems to exchange data or services.
