The above term stands for "Point to Point Protocol over Ethernet". So it's a combination of two widely accepted standards: PPP and Ethernet. Overall it specifies how a host computer connects with a broadband modem, whether it is a wireless router, cable or dsl modem. PPPoE is popular due to it's ease of use, it requires virtually no setup implementation by the end user and integration by Internet Service Providers. ISP's love it because they still use their dialup authentication system for their broadband service and can therefore sell the same line for multiple purposes. PPPoE has been in use for over 6 years now and is supported by most modern online applications, the downside is that PPPoE uses around 5% of a standard bandwidth. Security is increased for broadband users because they can choose to shutdown their PPPoE software and this will close the connection to the ISP. All that's required to use PPPoE is either an Ethernet card, adapter or external dsl modem which connects to the USB port.
