Numerical ID of the current WordPress user is stored in this global variable. It is set when the current user is created in the pluggable functions get_currentuserinfo() defined in [wordpress root folder]/wp-includes/pluggable-functions.php.

This global variable can be used to pass as a parameter to lot of WordPress functions which require this information. It is also useful when you have to build a custom SQL query for requesting information for this user. WordPress caches the user information by the user ID, it can be retrieved using this global variable, e.g.,

$user = wp_cache_get($user_ID, 'users');
