The LAMP Stack is a popular open-source software bundle used for web development and hosting dynamic websites and applications. The acronym stands for Linux (operating system), Apache (web server), MySQL (database management system), and PHP (programming language), though variations of the stack sometimes substitute PHP with Perl or Python. Each component plays a specific role in creating a robust and scalable environment for hosting and serving web applications.

Linux serves as the foundational operating system that provides the underlying infrastructure.
Apache is the web server responsible for handling HTTP requests and serving web pages to users.
MySQL is the relational database management system that stores and manages the application’s data, like user information or transaction records.
PHP is the server-side scripting language used to build dynamic web pages by executing scripts on the server before the results are sent to the client.
The LAMP stack is known for its flexibility, scalability, and cost-effectiveness, making it widely used for developing web applications, content management systems (CMS), e-commerce platforms, and more. It powers platforms like WordPress, Drupal, and Joomla and is popular for its open-source nature and community support.
