Glossary - 5

Hz. Hertz; A unit of frequency equal to one cycle per second.

Host Computer. A computer that serves other terminals in a network, providing such services as computation, database

access, supervisory programs and network control.

IDE. Intelligent drive electronics. Refers to the solid-state hard drive type.

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.

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.

imaging scanning . Mobile computers with an integrated imager use digital camera technology to take a digital picture of

a bar code, store the resulting image in memory and execute state-of-the-art software decoding algorithms to extract

the data from the image.

Intercharacter Gap. The space between two adjacent bar code characters in a discrete code.

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. 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.

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.
