HTML difference between <a> and <p>

BEGINNERS & HELP
#1

Hi Guys,

Basic question here:
Is there a fundamental difference between

and , if I don’t give an href attribute to the anchor?
At least the outcome seems to be the same.

Or is the difference mainly, that I can give different attributes and sub-tags to each tag, thus being able
to manipulate the content differently?
