Glossary GL-11
Interleaved 2 of 5 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.
Internet Protocol Address See IP .
I/O Ports interface The connection between two devices, defined by
common physical characteristics, signal characteristics,
and signal meanings. Types of interfaces include RS-232
and PCMCIA.
Input/Output Ports I/O ports are primarily dedicated to passing information
into or out of the mobile computer’s memory. Series 9000
mobile computers include Serial and USB ports.
IP 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.
IP Address (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.
IPX/SPX 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.
IS-95 Interim Standard 95. The EIA/TIA standard that governs the
operation of CDMA cellular service. Versions include IS-
95A and IS-95B. See
CDMA .
