Types of URLs:
There are two types of URLs: absolute and relative.
Absolute URLs:
Absolute URLs provide the complete address of a webpage, including the protocol (http:// or https://), domain name, and file path. They are used to link to webpages outside of the current website. Examples of absolute URLs include:
- http://www.example.com/index.html
- https://www.google.com/search?q=example
Relative URLs:
Relative URLs provide a partial address of a webpage, which is relative to the current webpage's location. They are used to link to webpages within the same website. Examples of relative URLs include:
- index.html (links to a webpage in the same directory)
- ../about.html (links to a webpage in the parent directory)
- /contact.html (links to a webpage in the root directory)
Difference between Absolute and Relative URLs:
- Absolute URLs include the full address, while relative URLs only include a partial address.
- Absolute URLs can be used to link to any webpage on the internet, while relative URLs are limited to the current website.
- Absolute URLs are typically longer and contain more information, while relative URLs are shorter and more concise.
Conclusion:
In summary, URLs can be classified into two types: absolute and relative. Absolute URLs provide the complete address of a webpage, while relative URLs provide a partial address relative to the current webpage's location. Understanding the difference between these two types of URLs is essential for effectively linking webpages within a website.
