PPPoE- (Point-to-Point Protocol Over Ethernet) using the PPP dial-up protocol with Ethernet as the transport. Used by many DSL providers, PPPoE supports the protocol layers and authentication widely used in PPP and enables a point-to-point connection to be established in the normally multipoint architecture of Ethernet. A discovery process in PPPoE determines the Ethernet MAC address of the remote device in order to establish a session.

Print Screen key- a command key on most computer keyboards that, depending on the application running, sends the image displayed on the monitor to the clipboard.
printed circuit board- (PCB) sometimes called a card, a sheet of nonconductive material containing electronic components such as transistors, resistors and chips used in virtually all modern electronic devices.
