Glossary
Multi-Tech Systems, Inc. RouteFinder RF802EW User Guide
The following is a glossary of terms used in this manual:
B
Baudrate
Baudrate refers to the number of bits per second (Bps) that are transmitted between your
network device and modem or ISDN TA.
D
DHCP (Dynamic Host Configuration Protocol)
A protocol that was made to lessen the administrative burden of having to manually configure
TCP/IP Hosts on a network. DHCP makes it possible for every computer on a network to extract
its IP information from a DHCP server instead of having to be manually configured on each
network computer. The DHCP server built-in to your RouteFinder allows every computer on your
network to automatically extract IP information from the RouteFinder.
Why is it called Dynamic?
Each time a network client turns on their computer your RouteFinder DHCP server will
automatically give them an IP address from the IP address pool configured in the DHCP
Configuration dialog box in RouteFinder Manager. It is called Dynamic because the address that
is issued could be different each time a computer connects to the network.
DNS (DomainNameSystem)
A DNS Server can be thought of as the computer at your ISP whose job is to take all the URLs
that you type into your web browser and translate them to their corresponding IP address. To
use this the DNS translator, you need to know the IP address of your ISP’s DNS Server.
E
Ethernet
A LAN (Local Area Network) protocol developed by Xerox and DEC. It is a very commonly used
type of LAN.
F
Firewall
A system designed to prevent unauthorized access to or from a private network. Firewalls are
typically installed to give users access to the Internet while protecting their Internal Information.
Your RouteFinder uses a firewall technology known as NAT (see NAT). Each message entering
or leaving the intranet passes through the firewall. The firewall examines each message and
blocks those that do not meet the specified security criteria.
Firmware
Software that has been has been permanently or semi-permanently written to the RouteFinder’s
memory. Your RouteFinder supports flash ROM which means you can upgrade the fimware in
your network device very easily by downloading a copy of the new firmware from the Multi-Tech
web site and using the RouteFinder Manager Upgrade Firmware function.
FTP (File Transfer Protocol )
A protocol which allows a user on one host to access,and transfer files to and from another host
over a network.
I
IP (Internet Protocol)
The Internet Protocol is the network layer for the TCP/IP Protocol Suite. It is a connectionless,
best-effort packet switching protocol.
Intranet
An Intranet is the use of Internet technologies within a company. Intranets are private networks
that exist only within organizations, while the Internet is a global network open to all.
