What does a uniform resource identifier (URI) refer to?

• A. A method for submitting data
• B. A unique identifier for each application
• C. A reference to a resource on the Internet
• D. A type of data format

Answer: (C)

A uniform resource identifier (URI) specifically refers to a reference that identifies a resource on the Internet. It serves the purpose of providing a simple way to connect to and retrieve resources, such as webpages, file resources, or services, and plays a crucial role in the architecture of the World Wide Web. URIs can take various forms, including URLs (Uniform Resource Locators), which not only identify a resource but also provide means to access it. By denoting each resource uniquely, URIs enable clear communication and reference within web technologies, ensuring that every resource can be distinctly identified and accessed. This functionality is pivotal for web development and data interchange, as it allows systems to locate and interact with services and data across the Internet seamlessly. The other options, while related to data and technology concepts, do not accurately capture the essence of what a URI represents. For instance, a method for submitting data relates more to forms or APIs, a unique identifier for each application doesn’t encompass the broader aspect of resource referencing that URIs inherently possess, and a type of data format concerns how data is structured or encoded, which is distinct from the concept of resource identification.
