DHTML

Dynamic HTML (dHTML) is a markup language designed to heighten the interactive browsing experience.

Because dHTML can utilize each action of the user (a mouseclick, a rollover, a keystroke), it provides a rich and transparent way to process this data.

One of the powerful abilities of dHTML is to pass JavaScript through a browser as part of a form. For example, when a user checks a box within an HTML form, that click of the mouse can be the action that launches a new window to give or receive further data.

PHP


PHP is an open-source scripting language that is embedded alongside HTML to perform interactive functions, such as accessing database information. PHP is similar to Microsoft’s active server page technology, but is used primarily on Linux web servers (or Windows servers with add-on software). An HTML page that has PHP script usually has a “.php” extension. Visit Webmonkey’s Tutorial:PHP Tutorial for Beginners to learn how it works.

Resolution


The resolution of an image describes how fine the dots are that make up that image. The more dots, the higher the resolution. A 300 dpi (dots per inch) printer is capable of printing 300 dots in a line 1 inch long. This means it can print 90,000 dots per square inch. When displayed on a monitor, the dots are called pixels. A 640-by-480-pixel screen is capable of displaying 640 distinct dots on each of its 480 lines, or about 300,000 pixels.

Statement


JavaScript statements make things happen. Every JavaScript program can be broken down into a series of statements, with each statement like an English sentence, except in JavaScript you end a sentence with a semicolon instead of a period. In fact, JavaScript is made up of sentences, phrases, and words. The sentences are statements, the phrases are expressions in which the elements of the action can be expressed and put together to make a statement, and the words are JavaScript operators, which are used to act upon the data passed to them.

WML is compatible with the wireless application protocol. It is a specialized version of XML and it is sometimes used in conjunction with WMScript to create dynamic content.
