A URL, or Uniform Resource Locator, is a unique identifier that specifies the location of a resource on the internet. It is also known as a web address. URLs are used to address web pages, images, videos, and other types of digital resources.
How do URLs work?
URLs are made up of a number of different components, including:
- Scheme: The scheme is the protocol that will be used to access the resource. For example, the scheme for web pages is
httporhttps. - Host: The host is the domain name or IP address of the server that is hosting the resource.
- Path: The path is the location of the resource on the server. For example, the path for the homepage of the Google website is
/. - Query parameters: Query parameters are used to pass data to the server. For example, the query parameter
q=googlecan be used to search for the word “google” on the Google website.
Example of a URL
Here is an example of a URL:
https://www.google.com/search?q=google
- Scheme: The scheme for this URL is
https, which means that the resource will be accessed using the HTTPS protocol. - Host: The host for this URL is
www.google.com, which is the domain name of the Google website. - Path: The path for this URL is
/search, which is the location of the Google search page on the server. - Query parameters: The query parameter
q=googleis used to pass the search term “google” to the server.
How to use URLs
To use a URL, simply enter it into the address bar of your web browser. The browser will then retrieve the resource from the server and display it to you.
URLs can also be used in other ways, such as in email messages and social media posts. When you click on a link in an email message or social media post, the browser will open the URL that is associated with the link.
