PAP/CHAP:	Password Authentication Protocol and Challenge Handshake
	Authentication Protocol (PAP/CHAP). Most ISPs use either one for
	user identification. If your ISP doesn’t support these two protocols,
	contact them for an authentication script.
PCI:	Peripheral Component Interconnect (PCI) is a specification introduced
	by Intel Corporation that defines a local bus system that allows up to 10
	PCI-compliant expansion cards to be installed in the computer.
PPP:	Short for Point-to-Point Protocol, a communications protocol for
	transmitting information over standard telephone lines between devices
	from different manufacturers.
PPPoE:	Short for PPP over Ethernet, relying on two widely accepted standards,
	Ethernet and the Point-to-Point Protocol. PPPoE is a communications
	protocol for transmitting information over the Ethernet between devices
	from different manufacturers.
Router:	An Internet device that routes requests for information to other routers
	until the information’s location is found and the data can be transmitted
	back to the origin of the request.
TCP/IP:	Short for Transmission Control Protocol and Internet Protocol, the suite
	of communications protocols that enable hosts on the Internet to connect
	and exchange streams of data.
MRU:	Maximum Receive Unit indicates the peer of PPP connection the
	maximum size of the PPP information field this device can be received.
	The default value is 1492 and is used in the beginning of the PPP
	negotiation. In the normal negotiation, the peer will accept this MRU
	and will not send packet with information field larger than this value.
MTU:	Maximum Transmission Unit indicates the network stack of any packet
	is larger than this value will be fragmented before the transmission.
	During the PPP negotiation, the peer of the PPP connection will
	indicates its MRU and will be accepted. The actual MTU of the PPP
	connection will be set to the smaller one of MTU and the peer’s MRU.
	The default is value 1492.
MSS:	Maximum Segment Size is the largest size of data that TCP will send in a
	single IP packet. When a connection is established between a LAN client
	and a host in the WAN side, the LAN client and the WAN host will
	indicate their MSS during the TCP connection handshake. The default
	value is 1432.
UBR:	Short for Unspecified bit rate.
WAN:	Wide Area Network. A System of LANs connected by telephone lines
	and/or radio waves.
