Graphics device, application

A graphics device either inputs or outputs graphical commands, or does both. These devices are controlled by a software component called a "device driver" that translates commands from a graphics application representation to output primitives for a specific graphics device, and vice versa if the device can be used for input. Because of different device technology, device drivers are... 

GDS defines the structure of application databases GKS standardizes access to graphics utilities and CGI communicates with graphics devices. PostScript provides a convenient method for general purpose display on a wide variety of devices. 

Some special memory structures do not follow the general accessing scheme of using an address. Two of the most frequently used are content addressable memory (CAM), and first-in-first-out (FIFO) memory. Another type of memory device, which accepts multiple addresses and produces several results at different ports, is called multiport memory. There is also a type of memory that can be written in parallel, but is read serially. It is referred to as video RAM or VDRAM since they are used primarily in graphic display applications. We will discuss these in more detail later. 

The obtainment of fine powders of PCL, poly(co-laurolactam), and their copolymers has attracted relevant attention in recent years for possible commercial utilizations in several fields. Cosmetic formulations, coating and graphic art applications, protein or enzyme immobilization techniques, rotational molding and sintering processes, and filtration devices in food and beverage industry are the major industrial fields where powdered polyamides are currently applied. Their use as stationary phase in chromatography has also been envisaged and introduced for some specific systems.
