Answer / Pritee Hardiha
In WordPress, actions and filters are hooks that allow developers to modify the functionality of a WordPress site. Action hooks trigger a function at a specific point during the execution process. Filters, on the other hand, allow developers to change or manipulate data before it is used or displayed. For example, 'wp_head' is an action hook that triggers a function in the <head> section of a WordPress page, while 'the_content' is a filter hook that allows modification of the post content before it is displayed.
