DNS Domain Name System. The system that associates the IP address assigned to a computer with the domain name. DNS server Domain Name System server. A server which maintains a database that translates the domain names of Internet servers, such as www.w3.org, into Internet Protocol (IP) addresses, such as "18.176.0.26". This enables clients to connect to a server with a host name rather than a numeric IP address. Domain A management concept that divides large scale networks into groups for identifying individual computers and users. The internet is managed by classifying domains according to geographical location or type (business, organization, educational institution, etc.). dpi Dots Per Inch. A measure of screen and printer resolution that is expressed as the number of dots that a device can print or display per linear inch. E 7 ECM Appendix Error Correction Mode. Reduces system and line errors when sending or receiving from another fax machine with ECM capability. ECM divides a page into blocks and inspects each block for data lost through poor transmission. If part of the data is missing in a certain block, ECM retransmits that data from the beginning of the block until it confirms that all the data within the block has been transmitted successfully. In this way, ECM guarantees that a good image can be received at the receiving end. ECM is very effective where the telephone lines are in poor condition. However, ECM slows the transmission speed, and you may turn this mode off, if it is not needed. Error lamp The error lamp flashes red when a paper jam occurs or the machine has run out of toner or paper. Ethernet An industry standard LAN (Local Area Network) system for connecting multiple computers. Data is sent from one computer to another by dividing it into packets, and the packets reach their destinations smoothly without any collision with other packets. 7-14 Glossary

the domain names of Internet servers, such as www.w3.org, into Internet Protocol
(IP) addresses, such as "18.176.0.26". This enables clients to connect to a server

Domain
A management concept that divides large scale networks into groups for identifying
individual computers and users. The internet is managed by classifying domains
according to geographical location or type (business, organization, educational
institution, etc.).
dpi
Dots Per Inch. A measure of screen and printer resolution that is expressed as the
number of dots that a device can print or display per linear inch.

ECM
Error Correction Mode. Reduces system and line errors when sending or receiving
from another fax machine with ECM capability. ECM divides a page into blocks and
inspects each block for data lost through poor transmission. If part of the data is
missing in a certain block, ECM retransmits that data from the beginning of the block
until it confirms that all the data within the block has been transmitted successfully. In
this way, ECM guarantees that a good image can be received at the receiving end.
ECM is very effective where the telephone lines are in poor condition. However, ECM
slows the transmission speed, and you may turn this mode off, if it is not needed.
Error lamp
The error lamp flashes red when a paper jam occurs or the machine has run out of
toner or paper.
Ethernet
An industry standard LAN (Local Area Network) system for connecting multiple
computers. Data is sent from one computer to another by dividing it into packets, and
the packets reach their destinations smoothly without any collision with other packets.
