Dedicated Line
A dedicated line is a permanent connection to the Internet using an
individual, separate phone line.
DHTML
Stands Dynamic Hypertext Mark-up Language.
DHTML is an HTML extension that allows web pages to react to the end
users' input, such as displaying a web page based on the type of browser
or computer end users are viewing a page with.
Directory
A directory (such as Yahoo, commonly mistaken for a search
engine) depends on people for listings. The main difference between
a search engine and a directory is that a directory does not make use
of a spider or robot. One
of the defining characteristics of a directory is that it is usually
divided into categories.
Dithered/Dithering
In order to display a full-color graphic image on a 256-color monitor,
computers must simulate the colors it cannot display. They do this by
dithering which is combining pixels from a 256-color palette
into patterns that approximate other colors. At a distance, the human
eye merges the pixels into a single color. Up close, the graphic image
will appear pixelated and speckled.
DNS
Stands for Domain Name System. The DNS translates
URL text addresses (such as grantasticdesigns.com) into a numeric Internet
address (such as 201.214.12.6).
Doorway Page
Web pages created specifically for search engine positions. Also known
as gateway page or a bridge page.
DPI
Stands for dots per inch. DPI specifies the resolution
of an output device, such as a printer or printing press machine.
Print resolution usually runs from 300-1200 dots per inch on a Laser
Printer and 125-225 dots per inch for photographic images on a print
brochure. (For information on input device measurements see ppi.)
Drop-Down Menu
In an online form, a drop-down menu (also known as a pull-down menu)
looks like the following:
If you click your mouse on the arrows, you will be able to select a
product or service. Drop-down menus are commonly used for web site navigation.
Drop Shadow
A drop shadow gives an image depth by creating a shading offset behind
a selected image.
Duotone
The application of two colors to provide richer tones than a monotone
(single-color image, usually grayscale)
can provide. A good duotone image can simulate a wider range of the
color spectrum than two colors used separately. Duotones also use a
hue (color) to set the mood for
a photo in a more stunning way than a full-color image can.
