DISCUS™ DRG A225G
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.
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
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 receiv-
ing data (known as the downstream rate) and from 16 to 640 Kbps when send-
ing 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.
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.
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.
Firewall
Electronic protection that prevents anyone outside of your network from seeing
your files or damaging your computers.
