  Glossary
I
I/O - Input/Output. Refers to the flow of information signals (in or out) with respective device. Every transfer is an output from one device and an input into another. @teqgear
IEEE - Institute of Electrical and Electronics Engineers, New York, www.ieee.org. A membership organization that includes engineers, scientists and students in electronics and allied fields. @teqgear
IEEE 802.11 - A family of IEEE standards for wireless LANs . The 802.11 standard is more widely known as "Wi-Fi". IEEE 802.11 applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS). @teqgear
IEEE 802.11a - The 802.11a standard uses the same core protocol as the original standard, operates in 5 GHz band, and uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 Mbit/s. @teqgear
IEEE 802.11b - Often called Wi-Fi, 802.11b is backward compatible with 802.11. IEEE 802.11b has a data transmission rate of 11 Mbps, sufficient for most non-motion data transmission applications. @teqgear
IEEE 802.11g - Applies to wireless LANs and provides 54 Mbps in the 2.4 GHz band (backwards compatible with b). @teqgear
Image - Visual counterpart or likeness of an object, a person, or a scene. @teqgear
Impedance -The opposition to the flow of alternating current in a circuit. Represented by the letter "Z" and measured in ohms, impedance is the combination of resistance, inductance and capacitance of the circuit. Video termination impedance is 75 ohms. @teqgear
Infrared (IR) - Relating to the range of invisible radiation wavelengths from about 750 nanometers, just longer than red in the visible spectrum, to 1 millimeter, on the border of the microwave region. @teqgear
 
J
Jacket - Outer protective covering of a wire or cable. @teqgear
JPEG - Joint Photographic Experts Group. An ISO/ITU standard for compressing still images. @teqgear
K
kHz - Kilohertz, a unit of frequency. One thousand cycles per second. @teqgear
L
LAN - Local Area Network. A computer network is two or more computers that communicate with each other through some medium. @teqgear
LCD - Liquid Crystal Display. A display technology that uses liquid crystals that flow like liquid and bend light. @teqgear
LED - Light Emitting Diode. A semiconductor device which converts electrical energy into electromagnetic radiation. The wavelength of the emitted radiation ranges from the near-ultraviolet to the near-infrared. usually red, green, yellow, blue, or white in color. Some LEDs can produce two different colors. @teqgear
Level - The relative intensity of an audio or video source. @teqgear
Line driver - A device that extends the transmission distance between terminals and computers connected via networks. @teqgear
Line out - Audio output. @teqgear
Login - The process of gaining access or signing in to a computer network. @teqgear
Lossless - Methods of compressing files (text, graphic etc.) without losing data. @teqgear
Loudspeaker - A device that converts electric signals to audible sound. @teqgear
