A hash is another term for an associative array.

• Hexadecimal: Web
Hexadecimal is a numbering system of base 16. The first nine numbers range from 1 thru 9. The next six numbers range from A thru F. ( A-F ) correspond to 10 thru 15 in the decimal numbering system. The first carry occurs at: ( F + 1 ) = 10 ( hex ). Hexadecimal ( 10 ) is the same value as ( 16 ) in the decimal system.

• Host Object: JavaScript
A host object is any object supplied by the host environment to complete the execution environment of ECMAScript. Any object that is not native is a host object. All of the objects belonging to the DOM and BOM are considered to be host objects.

• Hotspot: HTML
A hotspot is a mouse-sensitive area within an image that activates a hyperlink when the defined area is clicked.

• HTML: HTML
Hypertext Markup Language: HTML is a markup language designed for the Web. The most current version of HTML is version 4.01. HTML 4.01 is a minor update to HTML 4.0. HTML 4.0 was introduced in 1997 when it replaced HTML 3.2. The 4.0 version removed most of the presentation elements from the HTML specification in favor of using Cascading Style Sheets (CSS). Within the HTML 4.01 specification, there are three unique versions supported. The Transitional version still supports most elements and attributes that were removed from HTML 4.0. The Strict version of HTML 4.01 does not support the removed HTML items. And the Frameset version (nearly identical to the Transitional version) includes the specifications for framed documents. HTML is a SGML application. The HTML language is defined in a SGML DTD. Here the HTML elements, attributes, entities and other items are defined. HTML markup can represent hypertext news, mail, documentation, and hypermedia; menus of options; database query results; simple structured documents with in-lined graphics; and hypertext views of existing bodies of information.
