In the digital age, the full form of “URL” stands for “Uniform Resource Locator.” URLs are the web addresses that we use every day to access websites and online resources. They are the building blocks of the internet, enabling us to navigate the vast world of information on the World Wide Web. In this comprehensive guide, we will explore the details of URLs, their structure, and their essential role in web browsing.

What is a URL?

A Uniform Resource Locator (URL) is a web address used to specify the location of a resource on the internet. It serves as a link or reference to access web pages, documents, images, videos, and other online content. URLs are essential for web browsers to locate and retrieve information from web servers.

Structure of a URL

A typical URL consists of several components:

  • Scheme: The scheme specifies the protocol used to access the resource. Common schemes include “http,” “https,” “ftp,” and “mailto.”
  • Domain Name: The domain name (or hostname) identifies the web server where the resource is located. It can be a human-readable name, like “”
  • Port: The port number, if specified, indicates the specific port on the web server to use for the connection. It is often omitted and defaults to a standard port based on the scheme (e.g., 80 for HTTP, 443 for HTTPS).
  • Path: The path defines the specific location or directory on the web server where the resource resides. It follows the domain name and is separated by slashes.
  • Query: The query component, if present, contains parameters used to modify the resource’s behavior or content. It is preceded by a question mark.
  • Fragment: The fragment identifier, if included, points to a specific section within the resource, such as an anchor or a specific part of a webpage. It is preceded by a hash symbol (#).

Examples of URLs

Here are some examples of URLs:

  • This URL uses the “https” scheme to access the web server “”
  • This URL specifies an FTP (File Transfer Protocol) connection to the server “”
  • This URL points to a specific HTML file named “index.html” located in the “products” directory on the server “”
  • This URL includes a query parameter “q” with the value “url,” indicating a search operation.
  • This URL has a fragment identifier “#section3,” directing the browser to a specific section of the webpage.
