A Uniform Resource Locator (URL) is simply the address you enter in a web browser to access a particular website or web page. It consists of a protocol (like HTTP or HTTPS), a domain name, and possibly a specific path to a web page or a file on the web server. It helps your browser to accurately locate and display the Internet resource you’re looking for.
Uniform Resource Locator (URL) Examples
1. Example
The first URL example is https://www.google.com. This is the web address that takes you straight to Google’s home page. Each part of the URL serves a specific purpose.

“https://” is the protocol part of the URL. It tells your browser to use a secure, encrypted connection when communicating with the website. This is key for protecting your personal information, particularly when you’re entering sensitive data like passwords or credit card numbers.
The next part, “www”, is the subdomain. It’s an optional part of the URL that can be used for organizing different sections of the website, though many websites don’t use it anymore.
“Google” is the domain name. It’s the main identity of the website and is unique to Google. The “.com” at the end is known as the Top Level Domain (TLD), and it often represents the type of entity that hosts the website. “.com” is commonly used for commercial entities.
2. Example
The second URL, https://www.facebook.com/profile, directs you to the profile section of Facebook’s site. This URL also contains multiple sections each with different meanings.
Similar to the previous example, the “https://” part is the protocol instructing the browser to use a secure, encrypted connection. It’s essential for preserving the confidentiality and integrity of your data, especially on social media platforms like Facebook where personal information is being handled.
“www” is the subdomain, again, commonly used but optional. “Facebook” is the unique domain name that points to the Facebook site. “.com” is the TLD, typically associated with commercial entities given its origins as shorthand for ‘commercial’.
Importantly, “/profile” in this URL is what’s called the path. It tells your web browser, once it gets to the Facebook site, exactly where to go – in this case, your profile page. This is useful on large sites like Facebook where there are many different pages and resources.
3. Example
The third URL, http://example.com/pdf/sample.pdf, is another standard format. This one references a specific file on a server, which your browser can retrieve and display. The nature of the file is typically indicated in the URL itself.
The part “http://” is the protocol. In contrast to the other two examples, this protocol does not use an encrypted link. Although not recommended for sharing sensitive data, HTTP is commonly employed in public accessible web servers where any information shared is not required to be secured.
“example” is the unique domain name here, and “.com” as usual represents the TLD. There’s no subdomain in this case.
The part “/pdf/sample.pdf” is the path to the file. This specifies the exact location of the file on the server. The file is “sample.pdf”, housed inside a directory or folder named “pdf”. This kind of URL is common when you’re accessing specific resources on a website, such as a PDF document, an image, or a video file.
Conclusion
Understanding the structure of a Uniform Resource Locator (URL) helps to better navigate the web and understand the nature of the online resources you’re accessing. Whether you’re browsing a home page, navigating to a specific section of a site, or accessing a specific file, each part of the URL plays a critical role in guiding your web browser to the correct destination.
Key Takeaways
- URL stands for Uniform Resource Locator, which is the address of a specific webpage or file on the Internet.
- Every URL consists of several parts: a protocol, a domain name, and often a specific path or file on the web server.
- ‘http://’ or ‘https://’ is the protocol, which tells your browser whether to connect securely to the website.
- The domain name is the primary identity of the website, with a top-level domain (like ‘.com’ or ‘.org’) following.
- The specified path or file indicates a target location or resource on the website.
