Decode Algorithm. A decoding scheme that converts pulse widths into data representation of the letters or
numbers encoded within a bar code symbol.
Decryption. Decryption is the decoding and unscrambling of received encrypted data. Also see, Encryption
and Key.
Depth of Field. The range between minimum and maximum distances at which a scanner can read a symbol
with a certain minimum element width.
Device Configuration Package. The Symbol Device Configuration Package provides the Product Reference
Guide (PRG), flash partitions, Terminal Configuration Manager (TCM) and the associated TCM scripts. With
this package hex images that represent flash partitions can be created and downloaded to the mobile
computer.
DHCP. (Dynamic Host Configuration Protocol) Software that automatically assigns IP addresses to client
stations logging onto a TCP/IP network. Similar to BOOTP, but also permits the leasing of an IP address. It
eliminates having to manually assign permanent IP addresses. DHCP software typically runs in servers and
is also found in network devices such as routers that allow multiple users access to the Internet.
DHCP Server. A server in the network or a service within a server that assigns IP addresses.
Discrete Code. A bar code or symbol in which the spaces between characters (intercharacter gaps) are not part
of the code.
Discrete 2 of 5. A binary bar code symbology representing each character by a group of five bars, two of which
are wide. The location of wide bars in the group determines which character is encoded; spaces are
insignificant. Only numeric characters (0 to 9) and START/STOP characters may be encoded.
DNS Server. The Control Panel allows you to set the IP address for a DNS Server, if used. This allows users
to use server names, rather than IP addresses. It is set on the Network tab of the Control Panel.
Domain Name. The Control Panel allows you to set a Domain Name for the DNS Server, if used (e.g.,
symbol.com). It is set on the Network tab of the Control Panel.
DOS. Disk Operating System. This is basic software that allows you to load and use software applications on
your computer. Also see NetID.
DRAM. Dynamic random access memory.
E
EAN. European Article Number. This European/International version of the UPC provides its own coding format
and symbology standards. Element dimensions are specified metrically. EAN is used primarily in retail.
Element. Generic term for a bar or space.
Encoded Area. Total linear dimension occupied by all characters of a code pattern, including start/stop
characters and data.
