CPA is referred to as Cost per Acquisition.  It is a metric in Google Adwords that measures the cost you incur in order to attain a conversion. Generally, your cost per acquisition will be higher than your CPC (Cost per Click). This is because of the simple fact that not everyone who clicks on your Ad will go on and complete your desired action. Your desired action can be anything according to you business, Ex: making a purchase on your site or filling out a form to become a lead.
