Multi-Tech Systems RF802EW manual Glossary, B Baudrate, D DHCP Dynamic Host Configuration Protocol

Glossary

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.
