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 protocols. 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.
