Answer 1

First of all get your mind out of confusion and take it simple and you will understand.

URI => Uniform Resource Identifier Identifies a complete address of resource i-e location, name or both.

URL => Uniform Resource Locator Identifies location of the resource.

URN => Uniform Resource Name Identifies the name of the resource

Example

We have address https://www.google.com/folder/page.html where,

URI(Uniform Resource Identifier) => https://www.google.com/folder/page.html

URL(Uniform Resource Locator) => https://www.google.com/

URN(Uniform Resource Name) => /folder/page.html

URI => (URL + URN) or URL only or URN only
