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.

Document Object Model

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.

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.

An expression tells JavaScript what to do with the data it gets, and within each expression are operators and operands. Operands are the data or data types the expression gets, and operators are the shorthand characters that tell the expression what to do with the operand. JavaScript has arithmetic (+,-,*,/), assignment (=), bitwise (&, |), comparison (>, <,), logical (&, ||, !), special (., []), and string (+) operators. Operators are a feature of many programming and scripting languages. At first there were a relatively limited menu of operators to use in JavaScript, but version 1.2 allowed for the support of regular expressions and a group of operators large enough to compare to other scripting languages.

Akin to the notion “divide and conquer,” segmentation is marketingspeak for breaking your audience down into definable subcategories. For instance, Coca-Cola may segment its audience based on frequency (one can a month or five cans a day), location (Bangkok or Bangladesh), and many other criteria. On the web, segmentation is useful not just to marketers but to site designers as well, since the segments we track – IE vs. Mozilla, first-timer vs. repeat visitor, domestic vs. international – shape the way we develop and deploy our websites.
