FTP — file transfer protocol — A standard Internet protocol used to exchange files between computers connected to the
Internet.
G
G — gravity — A measurement of weight and force.
g — gram — A measurement of mass and weight.
GB — gigabyte — For memory, a gigabyte is a unit of data that equals 1024 MB (1,073,741,824 bytes) and measures drive
storage capacity.
GHz — gigahertz — A measurement of frequency that equals one thousand million Hz, or one thousand MHz.
Graphics Accelerator — A type of specialized video processor that boosts graphics performance.
Graphics mode — A video mode that can be defined as x horizontal pixels by y vertical pixels by z colors. Graphics modes
can display an unlimited variety of shapes and fonts.
GUI — graphical user interface — Software that interacts with the user by means of menus, windows, and icons. Most
applications that operate on the Microsoft Windows operating systems are GUIs.
H
Hard drive — A drive that reads and writes data on a hard disk. The terms hard drive and hard disk are often used
interchangeably.
Heat sink — A metal plate on some microprocessors that helps dissipate heat.
Hibernate mode — A power management mode that saves everything in memory to a reserved space on the hard drive and
then turns off the computer. When you restart the computer, the memory information that was saved to the hard drive is
automatically restored.
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.
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. Also called FireWire.
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. For example, the first serial connector in your computer is
typically assigned to IRQ4. Although two devices can share the same IRQ assignment, you cannot operate both devices
simultaneously.
