G

GPS

Global Positioning System is a worldwide satellite navigational system formed by satellites orbiting the earth and their corresponding receivers on the earth.

GSM

Global System for Mobile communications, is one of the leading digital cellular systems, and uses narrowband Time Division Multiple Access that allows eight simultaneous calls on the same radio frequency.

H

HDC

Hard Disk Controller is a special-purpose chip and circuitry that directs and controls reading from and writing to a computer’s disk drive.

I

IDE

Integrated Device Electronics is a disk drive interface where the controller electronics reside on the drive itself. This allows elimination of the need for a separate adapter card.

IEEE

IEEE stands for Institute of Electrical and Electronics Engineers, pronounced “I-triple-E.” Founded in 1963, IEEE is an organization composed of engineers, scientists, and students. IEEE is best known for developing standards for the computer and electronics industry.

I/O

I/O (Input/output). Two of the three activities that characterize a computer (input, processing, and output). Refers to the complementary tasks of gathering data for the microprocessor to work with and making the results available to the user through a device such as the display, disk drive, or printer.

IRQ

IRQ (Interrupt ReQuest). A method by which a device can request to be serviced by the device’s software driver. The system board uses a PIC to monitor the priority of the requests from all devices. When a request occurs, a microprocessor suspends the current operation and gives control to the device driver associated with the interrupt.

ISA

ISA (Industry Standard Architecture) is an 8-bit / 16-bit bus that provides a buffered interface from devices on expansion cards to the PC internal bus.

L

LAN

LAN (Local Area Network). A group of computers and other devices spanned over a relatively limited area (i.e. a single building).

LBA

LBA (Logical Block Address). A unit of data supplied or requested by a host computer.
