PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a

secure data transmission method originally created for dial-up connections;

PPPoE is for Ethernet connections. PPPoE relies on two widely accepted

standards, Ethernet and the Point-to-Point Protocol. It is a communications

protocol for transmitting information over Ethernet between different

manufacturers

Protocol: A protocol is a set of rules for interaction agreed upon between

multiple parties so that when they interface with each other based on such a

protocol, the interpretation of their behavior is well defined and can be made

objectively, without confusion or misunderstanding.

Router: A router is an intelligent network device that forwards packets

between different networks based on network layer address information such

as IP addresses.

Subnet Mask: A subnet mask, which may be a part of the TCP/IP information

provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured

like an IP address. It is used to create IP address numbers used only within a

particular network (as opposed to valid IP address numbers recognized by the

Internet, which must be assigned by InterNIC).

TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and

Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data

transmission over the Internet. Both TCP and UDP are transport layer protocol.

TCP performs proper error detection and error recovery, and thus is reliable.

UDP on the other hand is not reliable. They both run on top of the IP (Internet

Protocol), a network layer protocol.
