HTML Uniform Resource Locators (URLs) are used to identify resources on the internet, such as web pages, images, videos, and other files. URLs are made up of several components, including the protocol, domain name, path, and query string. Here’s a breakdown of each component:

  1. Protocol: This specifies the communication protocol being used to access the resource. The most common protocol is “http” (HyperText Transfer Protocol), which is used to access web pages.
  2. Domain name: This is the name of the server that hosts the resource. For example, “www.example.com” is the domain name for the website hosted on the server with the name “www” and the top-level domain “com”.
  3. Path: This specifies the location of the resource on the server. For example, “/index.html” would be the path to the homepage of a website.
  4. Query string: This is used to pass data to the server in order to modify the behavior of the resource being accessed. The query string is separated from the rest of the URL by a “?” and is made up of key-value pairs, with each pair separated by an “&”. For example, “http://www.example.com/search?q=html” would be a URL with a query string that searches for the term “html”.

Together, these components form a complete URL that can be used to access resources on the internet. URLs are often displayed in the address bar of web browsers, and can also be embedded in HTML code to create links between web pages.
