verifying that a particular name really belongs to a particular entity.
Asynchronous

B
Baud Rate
Baud Rate refers to the number of bits per second (Bps) that are transmitted between your network
device and modem or ISDN TA.
Blocked Cipher
Cipher that encrypts data in blocks of a fixed size: DES, IDEA, and SKIPJACK are block ciphers.
C
Client
A computing entity in a network that seeks service from other entities on the network. Client software
generally resides on personal workstations and is used to contact network servers to retrieve
information and perform other actives.

Block cipher that is widely used in commercial systems. It is a Federal standard so it is deemed
acceptable by many financial institutions.
Data Key
Crypto key that encrypts data as opposed to a key that encrypts other keys. Also called a session key.
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 Web browser management interface. 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.
Domain Name
The textual name assigned to a host on the Internet. The Domain Name Service (DNS) protocol
translates between domain names and numerical IP addresses.
