closeness of the matched font to the original determines how accurately the fonts are
reproduced on the printed page.
GB - See Gigabyte
GDI - Graphical Device Interface - software that utilizes the computer’s CPU and other
resources, rather than dedicated internal hardware, to perform the RIP function.
Gigabyte - GB, GByte - A unit of measure for memory or disk storage capacity equal to
1,024 MBytes.
GUI - Graphical User Interface – the feature of a program where the interaction with the
user is through high-resolution graphical screen displays (e.g., windows), and using
tools like a computer mouse, versus a line-by-line text method. For example, MS
Windows uses a GUI method, while MSDOS uses a line entry method.
Halftone computation - The process used by a RIP device to determine the size and
density of dot placement when rendering a halftone image.
Halftoning - The process of creating the illusion of continuous tone on a printed image
by breaking the image down into a series of dots. Varying the sizes and densities of
the dots in a halftone screen creates the optical illusion of variations of gray or
continuous color in the image.
Hard Disk/Drive - A computer storage device which uses a fixed, rotating platter as the
storage medium for computer applications and data.
Hardware - The physical, tangible components of the product.
Hub – A 10base-T device used to connect two or more computers to each other.
I/O - Input/Output.
I/O port – see I/O and Port.
IBM Compatible - A computer that adheres to IBM’s standards and is the equivalent in
performance.
IEEE - Institute of Electrical and Electronic Engineers – the U.S.–based standards-
setting and governing body of electrical engineers.
IEEE 1284 - Standard 1284 of the IEEE containing specifications of the bi-directional
parallel port used in the controller and PC.
IEEE 802.3 - Standard 802.3 of the IEEE describing the 10 Mbit Ethernet LAN.
IEEE 802.3u - Standard 802.3u of the IEEE describing the 100 Mbit Ethernet LAN.
Image Overlay - The process of combining two digitized images onto a single digital
duplicator master utilizing 1) the scanner in the digital duplicator and 2) a digitized
image sent to the controller.
ISDN - Integrated Services Digital Network - digital telephone technology permitting the
simultaneous transmission of voice, data, and video.
KB - see Kilobyte.
Kilobyte - A unit of measure for memory or disk storage equal to 1,024 bytes.
