A URI, or Uniform Resource Identifier, is a string of characters that identifies a particular name or resource, serving as a unique identifier for locating resources on the internet.
URIs include both URLs (Uniform Resource Locators) and URNs (Uniform Resource Names), collectively providing a standardized way to reference resources.
The URI "https://www.example.com/products/laptops" uniquely identifies the location of a webpage about laptops.
Understand the difference between URIs, URLs, and URNs, and use URIs consistently for resource identification.
