Most of the ISPs (Internet Service Providers) from all over the world offer broadband internet subscriptions. Some of them do it through a technology called PPPoE (Point-to-Point Protocol over Ethernet).

Typical use of PPPoE involves leveraging the PPP facilities for authenticating the user with a username and password.

It also offers an ISP an easier way to track exactly how much bandwidth you are using.

Throughput tells you how much data was transferred from a source at any given time.

Bandwidth tells you how much data could theoretically be transferred from a source at any given time.
