I
IEC.
International Electrotechnical Commission. This international agency regulates laser safety by specifying various
laser operation classes based on power output during operation.
IEC (825) Class 1.
This is the lowest power IEC laser classification. Conformity is ensured through a software restriction
of 120 seconds of laser operation within any 1000 second window and an automatic laser shutdown if the scanner's
oscillating mirror fails.
IEEE Address.

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 wearable terminals 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
.
L
laser scanner.
A type of bar code reader that uses a beam of laser light.
