LAMP is the name of a group of applications that are commonly used together for creating web applications.
- L stands for Linux: the operating system
- A for Apache: the server
- M for MySQL: the database management system
- P for Perl, PHP, or Python: the programming language
All of these applications are open source and popular in their own right. This means the software is cheap and very reliable. Often parts are replaced with different applications. However the ones listed are the most likely to be used together.
