In computer science, architecture means the conceptual arrangement of a system’s components.
Taking the analogy of a physical building, if a website’s individual pages are rooms, its architecture is the hypertextual relationship between the rooms within the structure.
In computer graphics, a color look-up table, or CLUT, is the set of available colors for a given application.
For example, a 24-bit system can display 16 million unique colors, but a given program would use only 256 of them at a time if the display is in 256-color mode. The CLUT in this case would consist of the 16 million colors, but the program’s palette would contain only the 256-color subset. To avoid dithering (i.e., varying the pattern of dots in an image) on 8-bit machines, you should only use colors from a predesignated CLUT.
The document object model (DOM) is the specification for how objects on a web page are represented.
A DOM defines each object on a web page (images, text, scripts, links, etc.) and also defines what attributes are associated with these objects and how they can be manipulated.
For example, in a normal array, you’d have:
dinner = "monkey brain";
dinner = "meatloaf";
But in a hash, you could use a string as the index:
dinner["monday"] = "monkey brain";
dinner["tuesday"] = "meatloaf";
The more modern definition of kiosk refers to public terminals that offer anything from internet access to travel information to ATM services. Electronic kiosks require a simple user interface and rugged hardware. Touchscreens enable a user to enter and display information without the need for a mouse or keyboard. Alternative input methods must be considered, however, for those who can’t use touchscreens, such as people with physical disabilities.
