What is a URL?

A URL (Uniform Resource Locator) is the address used to access resources on the internet, such as web pages, images, videos, or files. It specifies the location of the resource and how to retrieve it.

Structure of a URL:

A typical URL consists of several parts:

1. Protocol (https://):
   • Specifies the method used to access the resource, such as HTTP (Hypertext Transfer Protocol) or HTTPS (secure version of HTTP).
2. Subdomain (www.):
   • Optional; indicates a subdivision of the main domain.
3. Domain Name (example.com):
   • The unique name of the website.
4. Path (/path/to/resource):
   • Specifies the exact location of a resource on the server.
5. Query Parameters (?query=parameter):
   • Optional; provides additional information or instructions to the server.
6. Fragment (#fragment):
   • Optional; points to a specific section within a webpage.

Example of a URL:

• https://www.w3stuff.com/search?q=web
  • Protocol: https://
  • Domain Name: w3stuff.com
  • Path: /search
  • Query Parameters: q=web (search query is "web").

  Purpose of a URL:

  • It allows users to easily locate and access resources on the internet without needing to know the actual IP address of the server.
