Final answer:
OSGi and REST are categorized as Web service architectures, where OSGi is a modular framework for Java applications and REST is an architectural style for networked applications using HTTP.
Step-by-step explanation:
OSGi and REST are examples of c) Web service architectures.OSGi stands for the Open Services Gateway initiative, which is a framework for modular application development in Java. It allows different components, known as bundles, to be dynamically installed, updated, and managed within a Java virtual machine. On the other hand, REST, which stands for Representative State Transfer, is an architectural style for designing networked applications. It relies on a stateless, client-server, cacheable communications protocol -- the HTTP protocol.
Unlike traditional web services, which are tied to operations and services, RESTful web services are viewed as resources and can be identified by their URLs. REST is mostly used in the context of web services and refers to a way of providing interoperability between computer systems on the internet.OSGi (Java Open Services Gateway initiative) and REST (Representative State Transfer) are examples of web service architectures. They provide a framework for developing and deploying modular and scalable applications.
