118 GLOSSARY
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.
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.
DDNS Dynamic Domain Name Server. A method that enables Internet users to
tie their domain name(s) to computers or servers. DDNS enables a domain
name to follow an IP address automatically when the IP address changes.
DNS Server Address DNS stands for Domain Name System, which allows Internet host
computers to have a domain name (such as 3com.com) and one or more
IP addresses (such as 192.34.45.8). A DNS server keeps a database of
host computers and their respective domain names and IP addresses, so
that when a domain name is requested (as in typing “3com.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 modem DSL stands for digital subscriber line. A DSL modem uses your existing
phone lines to send and receive data at high speeds.
Encryption A method for providing a level of security to wireless data transmissions.
The Router uses two levels of encryption; 40/64 bit and 128 bit. 128 bit is
a more powerful level of encryption than 40/64 bit.
