the web standarts


Web pages are so-called hypertext pages.  Their appearance, text and image content is defined by a so called “HyperText Markup Language” or HTML.  The following text is in HTML and the output of these HTML lines read by a web navigator like MS Internet explorer is what you are actually reading.

Figure 2b. These few HTML lines, read by a web navigator, will look like the above displayed text.


Images are displayed as JPEG or GIF files. GIF and JPEG are compressed images, compression allowing shorter files; they can be transmitted faster by the net. These image file formats are used for the internet because people don't like to wait for the graphics to load.
