URI and URL
The simple understanding is this:
Understanding the difference between URI and URL, we introduce the concept of urn.
URI = Universal Resource Identifier Unified Resource
Marker
URL = Universal Resource Locator Unified Resources
Locator Characters
URN = Universal Resource Name Unified Resource
name
These three relationships are as follows:
That is, the URI is divided into three kinds, url or URN or (URL and URI)
The URL represents the path address of the resource, and the URI represents the name of the resource.
Locating a resource through a URL identifies the network location, such as:
- Http://example.org/absolute/URI/with/absolute/path/to/resource.txt
- Ftp://example.org/resource.txt
A resource is found by means of a URI that identifies the name in a namespace and does not represent a network address, such as:
The original URI includes the URL and urn, then the urn is not popular, resulting in almost all of the current URI is a URL
