Q-T
Quicktime - is a multimedia framework developed by Apple Inc., capable of handling various formats of digital video, media clips, sound, text, animation, music, and several types of interactive panoramic images.
Quick Mask Mode - Quick mask mode is a powerful way of selection in Photoshop. It is a selection based on the masking of the desired portion of an image. It is used for minute and accurate selections.
RGB - The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Rollover Button - a button that has been developed for a web page that usually reacts when the mouse is rolled over it.
RAM - Pronounced ramm, acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
Root Folder - A folder name selector will display all folders beneath this folder.
Search Engine - A Web search engine is a search engine designed to search for information on the World Wide Web. Information may consist of web pages, images and other types of files. Some search engines also mine data available in newsgroups, databases, or open directories. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically or are a mixture of algorithmic and human input.
Scripting Languages - A scripting language, script language or extension language, is a programming language that controls a software application. “Scripts” are often treated as distinct from “programs“, which execute independently from any other application. At the same time they are distinct from the core code of the application, which is usually written in a different language, and by being accessible to the end user they enable the behavior of the application to be adapted to the user’s needs. Scripts are often, but not always, interpreted from the source code or “semi-compiled” to bytecode which is interpreted, unlike the applications they are associated with, which are traditionally compiled to native machine code for the system on which they run. Scripting languages are nearly always embedded in the application with which they are associated.
Scratch Disk Memory - Scratch space is space on the hard disk drive that is dedicated for only temporary storage. It cannot be used to permanently backup files. Scratch disks can be set to erase all data at regular intervals so that the disk space is left free for future use. The management of scratch disk space is typically dynamic, occurring when needed. Scratch space is commonly used in graphic design programs, such as Adobe Photoshop. It is used when the program needs more memory, and the amount of available system RAM is insufficient.
Scrolling - In computer graphics and television, scrolling or text crawling is the act of sliding a horizontal or vertical presentation of content, such as text, drawings, or images, across a screen or display window. Scrolling is often used to show large amounts of data that could not fit on the viewport all at the same time, this is commonly used in window-based computer displays.
Thumbnail - Thumbnails are reduced-size versions of pictures, used to make it easier to scan and recognise them, serving the same role for images as a normal text index does for words.
TIFF File - Tagged Image File Format (TIFF) is a variable-resolution bitmapped image format developed by Aldus (now part of Adobe) in 1986. TIFF is very common for transporting color or gray-scale images into page layout applications, but is less suited to delivering web content.
Tone - Tone is any tint (relative lightness) or shade (relative darkness) of any similar colour.
Typography - is the craft, art, and science of type design, modifying type glyphs, and typesetting. Type glyphs (characters) are created and modified using a variety of illustration techniques. Details involved in the arrangement of type include the selection of typefaces, point size, line length, leading (line spacing), letter spacing, and kerning.
