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? Think of it like this:

- URI = *any* ID (e.g., `tel:+123456789`)
- URL = *location* ID (e.g., `https://example.com`)
- URN = *name* ID (e.g., `urn:isbn:123456789`)

Real-world use? APIs. Ever seen `api/users/1`? That’s a URI. Not always a URL (unless it includes `http://`).

For tools, try curl (curl.se)—it handles URIs like a champ.
