What is URI? Can someone explain it in simple terms? or What is URI and how is it different from a UR

what is uri? Simple: It’s *any* resource ID. URLs (locations) and URNs (names) are subsets.

Example:
- URI: `data:text/plain,HelloWorld` (just data, no location)
- URL: `https://google.com` (location)

Devs need this because browsers, servers, and APIs all speak URI. Check out RFC 3986 for the nitty-gritty.
