The network glossary contains explanation or information about common terms used in networking
products. Some of information in this glossary might be outdated, please use with caution.
RJ-45
Standard connectors for Twisted Pair copper cable used in Ethernet networks. Although they look
similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to eight wires, whereas
telephone connectors have only four.
100Base-TX
Also known as 802.3u. The IEEE standard defines how to transmit Fast Ethernet 100Mbps data using
Cat.5 UTP/STP cable. The 100Base-TX standard is backward compatible with the 10Mbps 10-BaseT
standard.
WAN
Wide Area Network. A communication system of connecting PCs and other computing devices across
a large local, regional, national or international geographic area.
LAN
Local Area Network. It is a computer network covering a small physical area or small group of
buildings.
DMZ
Demilitarized Zone. When a router opens a DMZ port to an internal network device, it opens all the
TCP/UDP service ports to this particular device.
PPPoE
Point-to-Point over Ethernet. PPPoE relies on two widely accepted standards; PPP and Ethernet.
PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common
broadband medium, such as single DSL line, wireless device or cable modem.
Transparent
Transparent mode works to transfer real IP address from WAN interface to the device that connects to
DMZ port. So the DMZ device can also get real IP address and offer the service with Internet users.
