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 Ether-
net (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 Router
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 Windows
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 net-
work (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 com-
puters and their respective domain names and IP addresses, so that when a domain name is requested (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 technology
(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 data at
high speeds.
