From video RAM (the frame buffer), the data is converted by a RAM digital-to-analog converter (RAMDAC) into analog(7)that are sent to the display presentation mechanism such as a cathode ray tube (CRT). Usually, video RAM comes in a 1 or 2 megabyte package and is(8)on the video or graphics card in the computer. Most forms of video RAM are dual-ported.

Each page element (division or section, heading, paragraph, image, list, and so forth) is(1)viewed as an "object." (Microsoft calls this the "Dynamic HTML Object Model." Netscape calls it the "HTML Object Model." W3C calls it the "Document Object Model.") For example, each(2)heading on a page can be named, given attributes of text style and color, and addressed by(3)name in a small program or "script" included on the page. This heading or any other element on the page can be changed as the result of a(4)specified event such as mouse passing over or being(5)clicked or a time elapsing. Or an image can be moved from one place to another by "dragging and dropping" the image(6)object with the mouse. These event possibilities can be viewed as the(7)reaction capabilities ofthe element or object. Any change takes place immediately since all variations of all(8)elements or objects have been sent as part of the same page from the Web server that sent the page. Thus, variations can be thought ofas different(9)properties ofthe object.
Not only can element variations change text wording or color but also everything contained within a heading object can be(10)replaced with new content that includes different or additional HTML as well as different text. Microsoft calls this the "Text Range technology."

1．reaction 2．specified 3．elements 4．name 5．clicked
