Hooks in WordPress are functions that allow you to interact with your WordPress site at specific points during the execution of PHP code. There are two main types of hooks: actions and filters.

1. Actions: These hooks allow you to execute custom functionality at various points in the WordPress life cycle (e.g., `init`, `wp_head`, and `save_post`). You can attach your functions to these action hooks using the `add_action()` function.
2. Filters: These hooks enable you to modify or manipulate data before it is saved or outputted by WordPress (e.g., post content, user registration details, and comment text). You can use the `add_filter()` function to attach your functions to filter hooks.
