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 between
multiple parties so that when they communication 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.

WAN:
Stands for Wide Area Network. A network that connects
computers located in geographically separated areas (e.g. different
