Web Site Jargon

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 of text.

Bitmap or Bit Image Graphic (.bmp) [File Type] - a graphic image composed from a pattern of dots, the position of each dot in the image must be specified as RGB, often used to distinguish images which are pixel based as compared to images which are vector based. A screen grab/shot from your monitor is a .bmp image.

Bitmapped Character [Typographics] - a character printed from a pattern of dots, the data specifying the dot pattern of each character is represented as a fixed pattern of dots, as opposed to Postscript characters or fonts.

Byte [Measurement] - a computer data unit, which represents a single character for most languages. One Byte is made up of eight bits.

Bullet [Typographics] - special typographic symbols, normally used to mark a list entry in a report for example.

C

Character set [Typographics] - a specific collection of letters, numbers and symbols, usually used to provide the characters needed in a particular language.

CMYK [Colour] - a subtractive colour model used in colour-printing systems 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.

Colour Lookup Table [Application Feature] - see "Palette".

Colour Space [Colour] - a mathematical model that describes colours. Common models include RGB, CMYK. Also called "Colour Model".

G

Gamma [Principle] - a curve describing how the mid tones of an image appears (Not to be confused with 'brightness' and 'contrast'). Changing the value of the gamma affects middle tones while the white and black of the image is unaltered. Gamma adjustment is used to compensate for differences between Macintosh (1.8) and Windows (2.2) displays.

Gamut [Colour] - the range of possible colours within a given colour space. For example, the gamut of video playback is dramatically more limited than the gamut of the RGB colour space of computer monitors.

GIF (.gif) [File Type] - Compuserve Graphics Interchange Format. A bit-mapped graphics file format limited to images up to 256 (8-bit) colours. This format is widely used online and works best with illustrations with areas of flat colour. (JPEG is a better option for photographic images.)

KiloByte (KB) [Measurement] - a unit that describes file size. A KiloByte is 1024 Bytes. The term 'KBps' is short for KiloBytes per second, which is a unit of data rate measurement used in multimedia. Not to be confused with 'kbps' (see below). 1KB = 1024Bytes = 8192bits

Kilobit (kb) [Measurement] - a kilobit is 1000 bits. The term 'kbps' is short for kilobits per second, which is a unit of data rate measurement used in reference to audio data rates and telecommunications. Not to be confused with KBps (see above). 1000bits = 1kb = 125Bytes i.e. a kilobit is 8 times smaller (or slower referring to data transfer) that a KiloByte. e.g. 56kb modems operate at = 7KBps.

Q

R

RGB [Colour] - Red Green Blue. An additive colour space that directly translates to the red, green, and blue phosphors used in computer monitors. Each colour is described by the strength of its red, green, and blue components. The colour space has a very large gamut and can reproduce a very wide range of colours.

Resolution [Measurement] - the measure of a printer or output device's ability to produce finely detailed output - usually measured in dpi.

S

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.
