Difference between absolute and relative links?

Answer 1

like in linux you go to the particular file from root to the file that complete way from root to particular file you are searching is called absolute and relative means file exist in a same folder as brother said

Answer 2

Relative paths:
/images/june/image.png
Absolute paths:
http://www.mysite.com/images/june/image.png
You'll use relative links only when linking to pages or files within your site.
You must use absolute links if you're linking to a location on another website.
Is that simple.
