If you plan on engaging in Linux hosting, one of the things that you need to be familiar with is the LAMP. This refers to a software package that contains all the necessary software and tools to run a general purpose website thats run under a Linux server. The reason why they are bundled into a package is because the software is actually independently developed of each other.

The word LAMP is actually an acronym for the first letters of the names of the software that are included in the package, namely Linux, Apache, MySQL, and PHP. Heres a brief description of each one:

Linux the operating system itself. You cant have linux hosting without this.
Apache its the web server application. Its the program used to create the server where the website is hosted.
MySQL A relational database management system. It facilitates easy storage and easy retrieval of data for whatever purpose in web hosting.
PHP The programming language with which dynamic web pages are created from.
