Wamp server is a collection of programs you can use to turn your regular desktop PC to a fully compatible web server with HTTP, PHP, MySQL, PHPMyAdmin, SQLBuddy applications. The advantage is that it is easy configurable with the built-in tools. Also it is structured in the way that you have everything you need at a click distance. The configuration screens provide extra information how settings should look like. Another thing would be that the packed applications are configured to be compatible between them, all being automatic configured, you just unpack your script, database, application, run the installer (if it has any) and that's it.
