The Jargon Buster Directory is your central resource for locating
an explanation to typical terms found for within all industries , professions
and governments.
Use our directory to locate and decipher jargon that you would like an
explanation for.
Keeping our directory up to date and to include all the spheres where jargon
is used is a never ending task for us. We have started with what we can locate
but but it is a vast subject and can be very niche specific.
Are you in a profession or industry that uses jargon that is NOT included
here? Then why not send us your own jargon buster text and we will include
it within our database. to say thank you we will provide you with a return
link back to your web site.
This is another technology lead jargon that never seems to stand still with
its use of web site jargon forever evolving to confuse the ordinary
person in the street.
Creating web sites is a fairly simple task these days with an html editor
for example. However, as the web evolves, new coding languages have evolved
such as java and flash that now requires more dedicated understanding of
web site jargon.
Most young people are interested in the net and as such more young people
not only understand the jargon but are actively creating it as well -
web site jargon is definitely here to stay.
Media - Web Sites
8-bit [Colour] - monitor colour depth. Allows only 256 colours to be displayed
simultaneously also called '256 Colours' on the MacOS. Many older computers
only have 8-Bit displays that are inadequate to display true colour values
on screen.
16-bit [Colour] - monitor colour depth. Allows thousands (approx 32 thousand)
of colours to be displayed simultaneously, also called 'Thousands of Colours'
on the MacOS. This is still a poor choice to show true colour values on screen.
24-bit [Colour] - monitor colour depth. Allows millions (approx 16 million)
of colours to be displayed simultaneously, sometimes referred to as 'true
colour' producing images of photographic quality, also called 'Millions of
Colours' on the MacOS.
3:2 Aspect Ratio [Principle] - 35mm slides aspect ratio. 35mm frame size
is not the same as the ratio for PowerPoint's "On Screen Show", it is effectively
'narrower' or 'longer'.
4:3 Aspect Ratio [Principle] - a common display aspect ratio. 800x600 is
a 4:3 aspect ratio, also the approximate ratio for PowerPoint's "On Screen
Show".
A
Additive Colours [Colour] - a type of colour model such as RGB used by computer
screens that creates all the colours by adding varying amounts of the additive
primaries: red, green, and blue. When mixed in correct proportions, the additive
primaries produce white.
Ascender [Typographics] - the vertical part of some lowercase letters such
as b, d and h.
Aspect Ratio [Principle] - the ratio between the horizontal and vertical
dimension of your monitor display, or for example any other media such as
an A4 piece of paper. It is described as an arithmetical ratio, the dimensions
of A4 paper for example is 210x297mm, therefore the ratio = 1:1.41. Similarly
a common display aspect ratio of 800x600 pixels has a 4:3 aspect ratio.
B
Baseline [Typographics] - an imaginary line running along the base of lower
case letters.
Bit [Measurement] - Binary Digit. A bit is a single computer digit (either
a "1" or a "0"). Eight bits = 1 Byte, which is approximately a single character

based around 4- colour ink on offset lithographic presses (Magazines, Newspapers,
Brochures etc ) - cyan (C), magenta (M), yellow (Y) and keystone black
(K). Theoretically, 100% of each of C, M, and Y produces black, but in practice
black must be added to obtain a pure colour.
Colour [Colour] - our visual perception of wavelengths of light. Light is
processed and transmitted to the brain by the eye. The brain then interprets
the wavelengths as colour. The basic colours in the visible spectrum are
red, orange, yellow, green, blue, indigo, and violet.
Colour Depth [Colour] - possible range of colours that can be used in an
image. These are generally Grayscale, 8-bit, 16-bit, and 24-bit. Higher colour
depths provide a wider range of colours, but result in larger file sizes
for a given image dimension.

a colour contains, the more saturated it is.
Scalable Fonts [Typographics] - fonts which can be printed in a range of
sizes without coarsening their appearance.
Subtractive Colours [Colour] - colours that are formed by the absorption
or subtraction of frequencies of light. In a subtractive model such as CMYK,
a white surface reflects all wavelengths of visible light, while a black
surface absorbs them.
