Difference between pppoa and pppoe software

Pppoe is a tunneling protocol which allows layering ip, or other protocols that run over ppp, over a connection between two ethernet ports, but with the software features of a ppp link, so it is used to virtually dial to another ethernet machine and make a point to point connection with it, which is then used to transport ip packets, based on.
