CPA is when the advertiser only pays if a specific action is performed, CPM is when an ad is displayed on a site until the budget is exhausted. http://www.allthingssem.com/cpm-cpc-cpa/
CPA is affiliate program that pays when an offer (or something along those lines) are filled in / bought by someone. CPM is Cost Per Mile meaning cost per 1000 pageviews. That says that you get $x.xx for every 1000 pageviews. Usually the rates for banners are anywhere from $0.06 to $1+. It all depends on your traffic and ad network. CPM are usually banners, but there are other CPM options like pop-unders, intersitial ads, and sliding banners (also known as Layer Ads)
CPA : Cost Per Action (or Acquisition) that pay you for certain action CPM : Cost Per 1000 Impression that you have to pay for.
