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.
Access point: A access point 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).
