What is a WAMP Server?
WAMP stands for Windows (operating system), Apache (webserver), MySQL (database), and PHP (coding language). WAMP can be compared to two other close variants, namely:

LAMP (Linux, Apache, MySQL, and PHP) for Linux Systems and,
MAMP (Mac, Apache, MySQL, and PHP) for Mac OS operating systems

WAMP, therefore, is a localhost server for Windows Operating Systems that lets you manage, create, test, and develop websites without having to use a remote web server.
