What is the conclusion?
In summary, 'PPP over Ethernet' and 'PPP over ATM', as their names imply, are two network transfer protocols using two different transport technologies.

Most modern PCs and MACs have built-in ethernet adapter (usu 10/100) as part of the networking solution package in this era of technology. Ethernet comes in transfer speeds of 10, 100 and 1,000Mbps. It's become so ubiquitous that the lay terms 'LAN card' or 'network card' have become almost synonymous with it.

ATM (Asynchronous transfer mode), on the other hand, is a different technology started in early '90s. Designed initially for both LAN and WAN, nowadays ATM is used primarily only for WAN as its setup cost and desktop-end adapters are most expensive compared to ethernet.

ATM is more scalable as it supports transfer speeds of up to near 10,000Mbps. But most of us can't use PPPoA since we (the desktop users) usually don't have an ATM adapter installed.

For most, PPPoE would suffice. We are mostly 512 or 1Mb tmnut screamyx users, aren't we? biggrin.gif
