Difference Between Absolute URLs and Relative URLs

What are Absolute URLs?

Absolute URL requires you to place the entire address on the page that you link to. An example of an absolute URL would look like this:

<a href = http://www.example.com/abc-page.html>

What are Relative URLs?

The relative URL, on the other hand, does not use the full address. It assumes that the page you type in is on the same site. An example of a relative URL would look like this:

<a href = /abc-page.html>
