What is a URI (Uniform Resource Identifier)?

URI (Uniform Resource Identifier) is a string of characters used to identify a resource. This can be a web page, image, file, or any other object on a network or local system.

There are two main types of URI:

• URL (Uniform Resource Locator): Specifies the location of the resource and how to access it.
• URN (Uniform Resource Name): Uniquely identifies the resource but does not specify its location.

The structure of a URI typically includes:

• Scheme (e.g., http, https, ftp, mailto)
• Authority (e.g., domain name or IP address)
• Path to the resource
• Query string (additional parameters)
• Fragment (section within the resource)

Example URL:

https://www.example.com/path/to/resource?param1=value1&param2=value2#section
