| Icon |
a little picture that represents
something you can do (an application), or a file that you've
created. Icons are used mainly on computers such as the Macintosh,
which has a mouse to select them, although mM computers now

Presentation Manager. |
| Image processing |
the
computation and manipulation of data from a picture in order
to change its characteristic for some purpose. |
| Input |
anything
you put into a computer, either by typing on a keyboard, using
a mouse, scanning in documents, or inserting a diskette. |
| Inputscanner |
the
electronic device that scans the original copy to convert each
pixel from an optical value to an analog or digital voltage.
It may use either a revolving drum, flat bed or flying spot
to image onto a photo-diode array, charge-coupled device (CCD)
or photomultiplier. |
| Interactive |
a
computer program in which you enter commands directly and watch
the results as they happen. Most programs today work interactively.
Interactive processing is the opposite of batch processing.
|
| Interface |
interface,
as a noun, refers to how the functionality of an application
is presented on the computer screen. |
| ISDN |
Integrated Services Digital Network.Digital
telecommunications lines that can transmit both voice and digital
network services up to 128K, and are much faster and more reliable
than high-speed analog modems.ISDN lines are offered by many
telephone companies. |
| .JPG |
file extension for JPEG (Joint Photographic
Experts Group).A file stored in JPEG format.JPEG,an ISO/ITU
standard for storing images with high compression capability,
uses a discreet cosine transform that can achieve compression
rates of 100:1 (significant loss of data from original) and
20:1 (minimal loss).C-Cube Microsystems introduced the first
JPEG chip. |
| K or Kilobyte |
one
thousand bytes, a measure of data size. More precisely, a K
is 2 to the 10th power, or 1024 bytes. A page of double-spaced
typing contains about 1.5 K of information. |
| Kbps |
Kilobits per second
or one thousand bits per second |
| Kerning |
removing
space between letters to make them fit together tighter and
look better. |
| Kerning pairs |
Kerning
pairs particular pairs of letters which are usually kerned to
look better in type. Typical kerning parts include "Po"
and "To" and "Ye". |
| LAN |
(Local
Area Network) -A group of interconnected computers and peripherals
which communicate with each other at high speeds. LANs are usually
confined to a single building or several adjacent buildings.
|
| Land line |
a copper wire or fiber optic cable
above or below ground used to send data. Traditional wired
telephone service, rather than wireless service. |
| Landscape |
horizontal
page orientation, versus portrait, or vertical |
| Laser printer |
a
printer that uses an electrostatically-charged drum to produce
characters on a page, somewhat like a photocopying machine.
The laser produces the static charge that attracts powdered
toner to the page; it does not bum an image into the page, as
many people believe. |
| Lines per inch |
(lpi)
-number of input scans or output exposure lines per inch crosswise
to the direction or travel of the device. |
| Logical Disk |
A software function that allows users
to construct file systems that span multiple physical disks.
Logical disks are built on physical disks and a logical disk
can use pieces from as many a 32 physical disks. (See
Physical Disk) |
