What are the components that make up a URI?

A Uniform Resource Identifier (URI) is a string of characters used to identify a resource on the internet, and it consists of several key components that help locate and access that resource. The correct answer identifies these essential parts accurately.

The first component is the protocol, which specifies the method used to access the resource, such as HTTP or HTTPS. This delineates how data is transferred and ensures that the correct procedures are followed for communication.

The second component is the server or host address, which indicates the location of the resource on the internet. This is typically represented as a domain name (like www.example.com) or an IP address.

The third component is the resource itself, which can refer to a specific file, webpage, service, or any identifiable element available at the given server.

Lastly, parameters may be included to pass additional data to the resource, often used in web applications for filtering or querying purposes. This allows for dynamic content retrieval based on the user's needs or input.

This combination of protocol, server/host address, resource, and parameters accurately reflects the structure of a URI, enabling effective communication and data transfer on the internet.
