Glossary
802.11b
The IEEE specification for wireless Ethernet which allows speeds of up to 11 Mbps. The standard provides
for 1, 2, 5.5 and 11 Mbps data rates. The rates will switch automatically depending on range and environ-
ment.
802.11g
The IEEE specification for wireless Ethernet which allows speeds of up to 54 Mbps. The standard provides
for 6, 12, 24, 36, 48 and 54 Mbps data rates. The rates will switch automatically depending on range and en-
vironment.
10BASE-T
The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5 twisted pair cable.
100BASE-TX
The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable.
Access Point
An Access Point is a device through which wireless clients connect to other wireless clients and which acts
as a bridge between wireless clients and a wired network, such as Ethernet. Wireless clients can be moved
anywhere within the coverage area of the access point and still connect with each other. If connected to an
Ethernet network, the access point monitors Ethernet traffic and forwards appropriate Ethernet messages to
the wireless network, while also monitoring wireless client radio traffic and forwarding wireless client mes-
sages to the Ethernet LAN.
Ad Hoc mode
Ad Hoc mode is a configuration supported by most wireless clients. It is used to connect a peer to peer net-
work together without the use of an access point. It offers lower performance than infrastructure mode, which
is the mode the router uses. (see also Infrastructure mode.
Auto-negotiation
Some devices in the range support auto-negotiation. Auto-negotiation is where two devices sharing a link,
automatically configure to use the best common speed. The order of preference (best first) is: 100BASE-TX
full duplex, 100BASE-TX half duplex, 10BASE-T full duplex, and 10BASE-T half duplex. Auto-negotiation is
defined in the IEEE 802.3 standard for Ethernet and is an operation that takes place in a few milliseconds.

Bandwidth
The information capacity, measured in bits per second, that a channel can transmit. The bandwidth of Ether-
net is 10 Mbps, the bandwidth of Fast Ethernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps.
Category 5 Cables
One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586 standard. Category 5 can be
used in Ethernet (10BASE-T) and Fast Ethernet networks (100BASE-TX) and can transmit data up to
speeds of 100 Mbps. Category 5 cabling is better to use for network cabling than Category 3, because it
supports both Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) speeds.
Channel
Similar to any radio device, the Wireless Cable/DSL router allows you to choose different radio channels in
the wireless spectrum. A channel is a particular frequency within the 2.4GHz spectrum within which the Rou-
ter operates.
Client
The term used to described the desktop PC that is connected to your network.
DHCP
Dynamic Host Configuration Protocol. This protocol automatically assigns an IP address for every computer
on your network. Windows 95, Windows 98 and Windows NT 4.0 contain software that assigns IP addresses
to workstations on a network. These assignments are made by the DHCP server software that runs on Win-
dows NT Server, and Windows 95 and Windows 98 will call the server to obtain the address. Windows 98
will allocate itself an address if no DHCP server can be found.
DMZ
DMZ (Demilitarized Zone) is an area outside the firewall, to let remote users to have access to items on your
network (Web site, FTP download and upload area, etc.).
DNS Server Address
DNS stands for Domain Name System, which allows Internet host computers to have a domain name (such
as pirelli.com) and one or more IP addresses (such as 192.168.10.8). A DNS server keeps a database of
host computers and their respective domain names and IP addresses, so that when a domain name is re-
quested (as in typing “pirelli.com” into your Internet browser), the user is sent to the proper IP address. The
DNS server address used by the computers on your home network is the location of the DNS server your
ISP has assigned.

DSL
Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this technol-
ogy (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5 to 9
Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data
(known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as
more areas around the world gain access.
DSL modem
DSL stands for digital subscriber line. A DSL modem uses your existing phone lines to send and receive da-
ta at high speeds.
Encryption
A method for providing a level of security to wireless data transmissions. The Router uses two levels of en-
cryption; 40/64 bit and 128 bit. 128 bit is a more powerful level of encryption than 40/64 bit.
Ethernet
A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet networks
use CSMA/CD to transmit packets at a rate of 10 Mbps over a variety of cables.
Ethernet Address
See MAC address.
Fast Ethernet
An Ethernet system that is designed to operate at 100 Mbps.
Firewall
Electronic protection that prevents anyone outside of your network from seeing your files or damaging your
computers.
Full Duplex
A system that allows packets to be transmitted and received at the same time and, in effect, doubles the po-
tential throughput of a link.
IEEE
Institute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets
standards for computers and communications.
