PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure
data transmission method originally created for dialup 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 ten numbers (for example, 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).
