What is the function of a URI in web services?

• A. To encode data
• B. To identify a resource on the server
• C. To control access to resources
• D. To store resource data

Answer: (B)

The function of a URI (Uniform Resource Identifier) in web services is primarily to identify a resource on the server. A URI provides a specific address that distinguishes one resource from another, allowing clients and servers to interact effectively. When a client makes a request to a web service, the URI in that request tells the server exactly which resource is being sought. This could be anything from a user profile, a list of items, or access to a specific service. The structure of the URI typically includes the server's address and the path to the resource, making it an essential component in the RESTful web service architecture. By focusing on resource identification, URIs enable standardized methods for accessing and manipulating resources. This foundational concept underpins how APIs are designed and used in web services, making resource identification a critical aspect of their functionality. Other options, while they might relate to different aspects of web services, do not capture the primary role of a URI as the means to identify resources directly.
