# URI 
A **Uniform Resource Identifier (URI)** is a sequence of characters that identify a physical or abstract resource. A URI can be a location, a name or, even both. In simpler terms, it's an identifier. 

# URL
On the other hand, a **Uniform Resource Locator (URL)**, contains information about how to fetch a resource from its location. A URL includes the resource’s location, as well as the protocol used to retrieve it. 

A URI can be a name or locator, or both, for an online resource while ​a URL is just the locator. All URLs are URIs, but not all URIs are URLs.

# Examples

A telephone number, such as *+1-234-567-8912*, 
is a **URI** since it acts as an identifier for a particular person. The telephone number does not give us the location of the person or how to get to them; therefore, it is not a URL.

However, *`ftp://example.com/file.zip`*
is a **URL** since it refers to a particular resource and has the location and protocol to fetch it. This URL is also a URI as it identifies the resource.

URI vs URL

A URI identifies a resource, abstract or physical. A URL specifies the location and retrieval protocol of the resource. URL is a subset of URI.
