URI
A URI (Uniform Resource Identifier) is a string of characters that unambiguously identifies a particular resource, such as a web page, file, or service on the internet. It serves as a standard format for naming and locating resources, with common types including URLs (Uniform Resource Locators) that specify how to retrieve a resource and URNs (Uniform Resource Names) that provide a persistent name regardless of location.
Developers should learn about URIs because they are fundamental to web development, APIs, and networking, enabling consistent resource identification across systems. They are essential when building web applications, handling hyperlinks, configuring RESTful APIs, or working with any technology that involves resource addressing, such as HTTP requests, database connections, or file paths in distributed environments.
