PawPrint.net Glossary of Terms

This dictionary of web design, photography, computer and graphic design terms has been compiled from many sources and is constantly being augmented and undergoing revisions to try and capture as much of the lingo and technical vocabulary as possible.  

Random terms, by category

Data and Telecommunications, terms, concepts and abbreviations. (19 terms)
Data Warehouse

DPI
A measure of image resolution - typical screen resolution is 72 dip whereas printing presse print at 300dpi.

When measuring the resolution of an image you need to know both the physical size and the resolution (in DPI) to acertain the actual amount of data. For example:

An image that is 10 inches wide...

at 72dpi would be 720 pixels wide
at 300dpi would be 3000 pixels wide (roughly 3.5 times the resolution)

Linux/Unix Terms and Commands. (9 terms)
FTP
A protocol developed to enable the transfer of files across a network. It provides a reletively insecure username and password  security but has been more recently enhanced to allow for SSL encryption to provide a secure password exchange.

To some extent the use of FTP has been superceeded by SFTP (a component of SSH) or the secure file transfer protocol.

Photography terms and concepts, including digital and traditional photographic techniques. (11 terms)
Aperture
The opening of a lens that admits light. Except in very simple cameras, the Aperture can be varied in size by an adjustable  diaphragm, which regulates the amount of light passing through the lens. The relative Aperture is measured as the focal length of the lens divided by the diameter of the Aperture; this is expressed as an f-number: f/3, f/5, and so on.

Aperature has a dramatic effect on the Depth-of-field of the photograph.

Web design termonology, concepts, and abbreviations. (46 terms)
SGML
