Address Resolution
Protocol
Protocol defined in RFC 826 to allow a network element to correlate a
host IP address to the Ethernet address of the host. See
http://www.faqs.org/rfcs/rfc826.html.
Bridge Network element that uses the physical address (not the logical address)
of another to pass data. The bridge passes the data to either the
destination address, if found in the simple routing table, or to all
network segments other than the one that transmitted the data. Modules
are Layer 2 bridges except that, where NAT is enabled for an SM, the SM
is a Layer 3 switch. Compare to Switch and Router, and see also NAT.
DES
Data Encryption Standard. An over-the-air link option that uses secret
56-bit keys and 8 parity bits. DES performs a series of bit permutations,
substitutions, and recombination operations on blocks of data.
DHCP
Dynamic Host Configuration Protocol, defined in RFC 2131. Protocol that
enables a device to be assigned a new IP address and TCP/IP
parameters, including a default gateway, whenever the device reboots.
Thus DHCP reduces configuration time, conserves IP addresses, and
allows modules to be moved to a different network within the system.
See http://www.faqs.org/rfcs/rfc2131.html. See also Static IP Address
Assignment.
DNS
Domain Name System, a system for naming computers and network
services that is organized into a hierarchy of domains
File Transfer Protocol Utility that transfers of files through TCP (Transport Control Protocol)
between computing devices that do not operate on the same platform.

FTP File Transfer Protocol, defined in RFC 959. Utility that transfers of files
through TCP (Transport Control Protocol) between computing devices
that do not operate on the same platform. See
