Network Glossary
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.
