(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.
IOCTL. Input/Output Control.
Intercharacter Gap.
Interleaved Bar Code. A bar code in which characters are paired together, using bars to represent the first
character and the intervening spaces to represent the second.
Interleaved 2 of 5.
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 terminal'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.
K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and
Decrypting.
The space between two adjacent bar code characters in a discrete code.
A binary bar code symbology representing character pairs in groups of five bars and five
