|
where
-
http is the hyperlink web service
-
www.place.org is the internet name of the web server

Types of files follow the standard MIME (Multipurpose Internet Mail Extensions) originally developed to include multimedia and multi-part content with electronic mail messages.
|
|
File extensions on the server tell which MIME format the file is in.
|
|
The browser is configured to have a set of helper applications or "plug-ins" to appropriately display or play files in various MIME formats.
