How to Ask includes "Have you thoroughly searched for an answer before asking your question?" and the downvotes may be because it would appear you have not. Just reading the tag wiki or googling "What is a PPP Adapter" would seem to be quite sufficient to answer the question in your title. If you don't, say, develop "How does it help in normal pc?" your question might be closed. – pnuts Dec 28 '12 at 19:57

@0x1gene SE sites are very highly ranked by Google so first hit is common - but there are others. (And that would not have been the first hit for someone researching before asking - though no doubt Google are working on that!) – pnuts Oct 17 '14 at 16:51

PPP stands for Point to Point Protocol. The adapter provides the computer the ability to use the protocol over the existing network interfaces. Originally PPP was used for dial-up access via Plain Old Telephone Systems (POTS), but is now used in conjunction with DSL internet connections and some VPN services to provide a framework for authentication and encryption between two points (usually PPPoE aka PPP over Ethernet).
