What is wamp server?
WAMP (Windows, Apache, MySQL, PHP/Perl/Python)
WAMP is a form of mini-server that can run on almost any Windows Operating System. WAMP includes Apache 2, PHP 5 (SMTP ports are disabled), and MySQL (phpMyAdmin and SQLitemanager are installed to manage your databases) preinstalled.
An icon on the taskbar tray displays the status of WAMP.
a) Red Icon
Red Icon appears if WAMP is running but no services are opened (Apache and MySQL Services are not running). This happens if IIS server was installed in the system prior to the installation of WAMP thus creating the clash of the port address where both the servers are trying to access http://localhost/
b) Orange Icon
Orange Icon appears when WAMP is running and one service is opened (either the Apache or MySQL service has not been started). This usually happens due to the conflict of port 80 being used by other programmes like Skype, Teamviewer etc.
c) Green Icon
Green icon tell that WAMP is running with all services opened (Apache and MySQL Service started)
The files/web pages that are hosted on your WAMP server can be accessed by typing http:/localhost or http://127.0.0.1/ in the address bar of your web browser. WAMP must be running in order to access either of the above addresses.
