abozzo In painting, the sketch or initial rough drawing over which the final painting is done.
abstract art An art form in which little or no realistic representation is present.
abstract expressionism a style of art in the 1940's and 1950's in which no attempt to represent reality was made. The style was usually characterized by non-geometric, emotionally intense and forceful use of color, brush strokes, and shape.
academy An educated group of authority figures in the fine art world.
access To find information stored in the computer's memory. (1) To select a keyboard command or menu bar to perform a task. (2) To search directories for a file (3) To establish keywords for a database search. See password.
access time The time frame between a request of computer information from storage or memory and delivery to a viewing or monitoring device.
accelerator (also accelerator board, coprocessor board, math accelerator, math coprocessor) A computer component, usually optional, dedicated to the enhancement of computer throughput to speed up calculation or graphics processing. This is done by off-loading computationally intensive tasks from the main processor (CPU), offering more registers, local cache memory and utilizing specially designed chips to perform math or graphics tasks at very high throughput speeds. Some coprocessors take over the computer, with an additional CPU of greater performance and memory handling capability - an alternative to the purchase of a new computer. For example, an 80286 board in an IBM XT (8086) or an 80386/SX in an IBM AT (80286) machine, or an 80486/SX in an IBM 80386 machine. Math coprocessors are companion chips which attach next to the CPU on the motherboard (8087 with an 8086 CPU, 80287 with an 80286 CPU). The CPU passes math computation to the extra chips and retrieves the result. See board, CPU, Drystone, Linpacs, MIPS, MFLOPS, and throughput.

Mixed in the proper proportions, they can form all other visible colors. Various record/display systems can form a large or small subset of all colors - no system can produce all possible colors. Used in optical imaging systems, e.g. theatrical lighting, photographic duplication (with dichroic filtration), television and color computer systems. They are the complimentary process to the subtractive primaries, cyan, yellow, and magenta that form all colors and black in printing and emulation, dye-based photography.
