A bar code in which characters are paired together, using
bars to represent the first character and the intervening
spaces to represent the second.
A binary bar code symbology representing character pairs
in groups of five bars and five interleaved spaces.
Interleaving provides for greater information density. The
location of wide elements (bar/spaces) within each group
determines which characters are encoded. This continuous
code type uses no intercharacter spaces. Only numeric (0 to
9) and START/STOP characters may be encoded.
See IP.
interface The connection between two devices, defined by
common physical characteristics, signal characteristics,
and signal meanings. Types of interfaces include RS-232
and PCMCIA.
I/O ports are primarily dedicated to passing information
into or out of the terminal's memory. Series 9000 mobile
computers include Serial and USB ports.
Internet Protocol. The IP part of the TCP/IP communications
protocol. IP implements the network layer (layer 3) of the
protocol, which contains a network address and is used to
route a message to a different network or subnetwork. IP
accepts "packets" from the layer 4 transport protocol (TCP
or UDP), adds its own header to it and delivers a
"datagram" to the layer 2 data link protocol. It may also
break the packet into fragments to support the maximum
transmission unit (MTU) of the network.
(Internet Protocol address) The address of a computer
attached to an IP network. Every client and server station
must have a unique IP address. A 32-bit address used by a
computer on a IP network. Client workstations have either
a permanent address or one that is dynamically assigned to
them each session. IP addresses are written as four sets of
numbers separated by periods; for example, 204.171.64.2.
Internet Package Exchange/Sequential Packet Exchange. A
communications protocol for Novell. IPX is Novell's Layer 3
protocol, similar to XNS and IP, and used in NetWare
networks. SPX is Novell's version of the Xerox SPP protocol.
Interim Standard 95. The EIA/TIA standard that governs the
operation of CDMA cellular service. Versions include IS-
95A and IS-95B. See CDMA.
Kerberos is a network authentication protocol. It is
designed to provide strong authentication for client/server
applications by using secret-key cryptography. A free
implementation of this protocol is available from the
Massachusetts Institute of Technology. Kerberos is
available in many commercial products as well.
A key is the specific code used by the algorithm to encrypt
or decrypt the data. Also see, Encryption and Decrypting.
Local area network. A radio network that supports data
communication within a local area, such as within a
warehouse of building.
