In Drupal 7, a theme function is a PHP function that is used to wrap the output variables with HTML. For adding a theme function in our custom Drupal 7 module, we need to implement hook_theme(). A theme function is prefixed with 'theme_'. However, they can't override existing theme functions. Such functions are invoked using theme() rather than being directly called. Also, they are faster compared to the template (.tpl) file implementations.
As the name suggests, a preprocess function is a precursor to a theme function. It runs first, irrespective of the fact that the theme function can also be implemented as a template (.tpl file) rather than a function. Preprocess functions can be implemented in both modules and themes. However, the preprocess implementations from modules run first, and those by themes run only last.
