Final answer:
REST is not strictly limited to client-server interactions.
Step-by-step explanation:
False. REST (Representational State Transfer) is an architectural style that defines a set of constraints for designing networked applications. While REST is often used in client-server interactions, it is not strictly limited to this. REST can also be used in server-to-server or even server-to-client interactions. For example, a RESTful API can be used by a mobile application to request data from a server.
