Hz — hertz — A unit of frequency measurement that equals 1 cycle per second. Computers and electronic devices are often measured in kilohertz (kHz),
megahertz (MHz), gigahertz (GHz), or terahertz (THz).
I
IC — Industry Canada — The Canadian regulatory body responsible for regulating emissions from electronic equipment, much as the FCC does in the United
States.
IC — integrated circuit — A semiconductor wafer, or chip, on which thousands or millions of tiny electronic components are fabricated for use in computer,
audio, and video equipment.
IDE — integrated device electronics — An interface for mass storage devices in which the controller is integrated into the hard drive or CD drive.
IEEE 1394 — Institute of Electrical and Electronics Engineers, Inc. — A high-performance serial bus used to connect IEEE 1394-compatible devices, such as
digital cameras and DVD players, to the computer.
infrared sensor — A port that allows you to transfer data between the computer and infrared-compatible devices without using a cable connection.
integrated — Usually refers to components that are physically located on the computer's system board. Also referred to as built-in.
I/O — input/output — An operation or device that enters and extracts data from your computer. Keyboards and printers are I/O devices.
I/O address — An address in RAM that is associated with a specific device (such as a serial connector, parallel connector, or expansion slot) and allows the
microprocessor to communicate with that device.
IrDA — Infrared Data Association — The organization that creates international standards for infrared communications.
IRQ — interrupt request — An electronic pathway assigned to a specific device so that the device can communicate with the microprocessor. Each device
connection must be assigned an IRQ. Although two devices can share the same IRQ assignment, you cannot operate both devices simultaneously.
ISP — Internet service provider — A company that allows you to access its host server to connect directly to the Internet, send and receive e-mail, and access
websites. The ISP typically provides you with a software package, user name, and access phone numbers for a fee.
K
Kb — kilobit — A unit of data that equals 1024 bits. A measurement of the capacity of memory integrated circuits.
KB — kilobyte — A unit of data that equals 1024 bytes but is often referred to as 1000 bytes.
keyboard shortcut — A command requiring you to press multiple keys at the same time. Also referred to as a key combination.
kHz — kilohertz — A measurement of frequency that equals 1000 Hz.
