What is the meaning of URI and URL? What are the significance of both and what are the differences between these two?

In the context of URI vs URL, let’s understand the URI first. URI stands for Uniform Resource Identifier. It is a string of characters that is used for identifying the resources. On the other hand, the URL refers to the Uniform Resource Locator which is a type of URI. It is mainly used to locate a resource by identifying the addresses. 

The components of a URL are Domain, path, and other additional elements. When all subparts are combined it works for accessing a file. On the other hand, the URI is a bigger term. It is like an umbrella term for many other sub-parts whose primary work is to identify the resources in a unique manner.

Understanding the differences between URI and URL is very crucial in the context of referring to the exact address of a resource (URL) or in general resource identifier (URL) in the field like web-based systems, protocols, or software.
