Open Source Technologies (OST) are the most popular technologies in the world. Open Source applications are those that provide their source code for others to read and build upon. There are a number of licenses commonly used by Open Source applications including GPL, LGPL, MIT, MPL and more. The Linux operating system is synonymous with Open Source software, as the code for the Linux kernel and much of its supporting application base is Open Source. However, every operating system, including Windows and MacOS, has Open Source applications written for them.
Technologies like Linux Operating System, Apache Web Server, Database Programming with MySQL and Web Application Development with PHP Project are all absolutely essential for the operation of any application or web/computer-based product.
