HTML — hypertext markup language — A set of codes inserted into an Internet web page intended for display on an Internet
browser.
HTTP — hypertext transfer protocol — A protocol for exchanging files between computers connected to the Internet.
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.
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.
L
LAN — local area network — A computer network covering a small area. A LAN usually is confined to a building or a few
nearby buildings. A LAN can be connected to another LAN over any distance through telephone lines and radio waves to form
a wide area network (WAN).
LCD — liquid crystal display — The technology used by portable computer and flat-panel displays.
