- The GNU General Public License is a free software license that guarantees users the freedom to run, study, share and modify the software. It’s often abbreviated as GPL.
- GPL is based on four main freedoms: the freedom to use the software for any purpose, the freedom to change the software to suit your needs, the freedom to share the software with your friends and neighbors, and the freedom to share the changes you make.
- When a program is under GPL, this means the software is licensed permissively, which is in contrast to proprietary software. Essentially, this allows the software to be free but also provides a legal framework to protect the rights of authors and users alike.

The GNU General Public License (GPL) is a vital aspect of technology because it represents a foundation of the free software movement. As a widely used license for free software, GPL ensures that software is freely shared and improved, while also protecting original creators. This license allows anyone to use, read, modify, and distribute the software or any modifications, under the stipulation that these freedoms are preserved in derivative works. In essence, GPL encourages innovation and collaboration by allowing individuals or organizations to improve on existing software, and its concept of ‘copyleft’ ensures that these improvements are freely available to every user. This makes the GPL a crucial vehicle for technological progress and inclusivity in the software world.
The GNU General Public License (GPL) is a free software license that guarantees end users the freedom to run, study, share, and modify the licensed software. The primary purpose of GPL is to uphold the freedom of all users of a certain program and prevent any efforts to exclude people from this benefit. This is achieved by obliging those who distribute the GPL licensed software, to disclose the source code and grant these four freedoms.GPL is utilized to license numerous software programs, including the GNU Operating System and the Linux kernel. The license ensures that derivative works of a software are also free, thus promoting the creation and sharing of creative extensions without the fear of legal ramifications. Therefore, not only does it motivate creative enhancements, but it also encourages collaboration amidst the software programming community.
1. Linux Operating System: Perhaps the most famous example of a GNU General Public License (GPL) product is the Linux operating system. Linux OS was created under the guidelines of the GPL, allowing anyone to use, modify and distribute its source code. It has now become a standard for servers, desktops, embedded systems, and smartphones.2. WordPress: The popular content management system, WordPress, is also released under GPL. This means that the software is open source, free for anyone to use, modify, and distribute. Many powerful websites and blogs are powered by WordPress thanks to its flexibility and the big community of developers who continually innovate and share their improvements with the public.3. GIMP: This refers to the GNU Image Manipulation Program, a versatile graphics manipulation package which provides sophisticated tools for graphic designers and photographers. It is licensed under GPL, meaning it’s freely distributed and allows for modification and improvements by the larger community.
