| EGA |
Enhanced Graphics Adapter. A graphics
adapter card that improved on the CGA (Color Graphics Adapter)
and was superseded by the VGA (Video Graphics Adapter). |
| EPS |
(Encapsulated PostScript) a file
format used for graphics, such as clip art, which are likely
to be incorporated into larger documents. The EPS format offers
greater display flexibility than other formats. |
| Error diffusion |
averaging
the difference of adjoining pixels to smooth out an area of
an digital image. |
| Ethernet |
Ethernet
is a local area network standard originally developed by Xerox.
It is a bus network which runs on thick or thin coaxial cable
and on twisted pair. Ethernet operates at 10 Mbps (megabits
per second). |
| Fiber optics |
used
as a communication vehicle to transmit digitized data over telephone
lines (fiber optics are the actual telephone lines -they replace
copper lines). Previously -the copper lines transmitted data
by electrical impulse, fibre optics transmit data by light.
The fiber optics signal is more accurate, faster, longer wearing
and higher capacity. |
| File |
a
set of information stored together under the same name, similar
to a file in a filing cabinet. A computer file can contain anything
you put there: text, graphics, a mailing list, even garbage.
|
| Firewire |
The former name for High Performance
Serial Bus. A serial bus developed by Apple Computer and Texas
Instruments (IEEE 1394).The High Performance Serial Bus can
connect up to 63 devices in a tree-like daisy chain configuration,
and transmit data at up to 400 megabits per second. It supports
plug and play and peer-to-peer communication between peripheral
devices. |
| Folder |
on
the personal computer, individual files are generally stored
within folders to make it easier to keep them organized on a
disk. |
| Footers |
running titles along
the bottom margin of a page. |
| Formatting |
preparing
a diskette or hard disk for use. A new disk is like a blank
piece of paper, with no guidelines the computer can use for
storing information. A formatted disk is like a piece of graph
paper, divided into convenient areas so the computer knows how
and where to store the information. "Formatting" is
also used to describe the process of adding typographic information
to a page of text. |
| Frame grabbing |
the
act of electronically capturing a single picture element, a
frame, from a video tape or an optical disk for the purpose
of viewing it, manipulating it or outputting it for reproduction
with ink on paper or on photographic material. |
| Freeware |
Freeware is software that is available
free of charge, but which is copyrighted by the developer, who
retains the right to control its redistribution and to sell
it in the future. Freeware is different from free software,
which has no restrictions on use, modification, or redistribution. |
| Gateway |
A device which connects two or more
dissimilar networks. Unlike routers, gateways can join networks of entirely different kinds. |
| Gigabyte |
one thousand megabytes
or one billion bytes. |
| Handshake |
the
first two-way signal exchange between two computers that determines
whether or not they are connected, compatible and ready to communicate.
|
| Hard disk |
a mass computer storage device, often
installed inside the computer chassis, or else kept in a separate
case beside it. |
| Hard Proof |
a
colour proof made on a substrate from production films or on
a substrate directly from the stored pixel data. The latter
is usually referred to as a digital hard proof, and a video
proof as a soft proof. |
| Hardware |
any physical pieces of computer. |
| Header |
running titles along
the top margin of a page. |
| Help |
a
way to get extra instructions on the operation of a piece of
software from the screen while you are using it. |
