i have problem understanding what he's saying!

when he wants to explain what do_action does , he says: execute where in the code you want a hook to take place!

can someone please explain it a little more clearer , probably with an example of real world usage of it?

thanks in advance .

When WordPress loads you can use hooks to "hook" into the load process. So lets say I want to write a custom menu for the dashboard. I would look for the hook that loads the dashboard then create a callback function to load my own menu for the dashboard. This will read my add_action() and render the custom code to the dashboard.

here is a solid blog post about hooks.
