Let's say, for example, that you want to write a document on your new blueberry imac and you want people who own IBMs to be able to read it. There are three steps. Your text will be read by a browser application. Netscape is a browser. Internet Explorer is a browser.
Lynx is a browser.
BedeNet's host then sends the document in the form of data through the telephone lines and your browser interprets it. As an analogy, imagine a piece of music which can be played by any number of instruments. The music, a collection of staves and notes on a sheet, makes no sound. It requires an instrument to interpret those notes. Similarly, a marked-up document will display no images, and neither will it show formatted text such as bold words or italicized words.
