What's cutting edge today may soon gain mainstream acceptance and usability. Most users, however, lag behind the cutting edge. They're not equipped with the most advanced equipment, software, or connections. Text elements, which are coded using HTML , or Hypertext Markup Language, transmit quickly and can be seen in all browswers. Most elements other than text involve much more data and take more time to transmit.
Pages containing such bandwidth-intensive elements, therefore, take longer to display.
Lengthy download times are an issue when your users lack high-speed connections to the Internet . Additionally, basic browser software supports only a subset of the possibilities. To access other kinds of elements, your users may need to download and install additional software. To help you resolve this tradeoff, this session provides an overview of some of the most common elements on the Web and the contexts in which they are used. We encourage you to experience them yourself before you decide what to use in your own resouce.
