mysql_free_result() question

I'm a bit unclear as to which result it is I use this function on. So lets say I; $Query = mysql_query("SELECT something FROM here"); $Result = mysql_fetch_assoc($Query); Do I mysql_free_result the $Query or the $Result? If it's $Result, would this be the same as just going unset($Result)?
