URLs are the way how applications give access to their information assets by defining well-structured endpoints. For example, if you want to search about Peru, you would probably access from a web browser the following URL: https://www.google.com/search?q=Peru. Let's divide the previous URL into parts and analyze it in details:

From the diagram, we see that there are basically four parts:

• Protocol: This is the HTTP for non-secure connections or HTTPS for secure connections
• Domain: The registered domain that will be translated to the server IP, which contains this resource
• Path: This allows us to separate our resources into segments
• Query String: This is optional but allows us to provide additional data

We will always use URLs to access resources hosted on another server.
