Free and Open-Source Software (FOSS)

Free and Open-Source Software (FOSS) is a type of software that gives users the freedom to run, copy, distribute, study, change, and improve the software. This is in contrast to proprietary or closed-source software, which is licensed under exclusive legal right of the copyright holder.

• Mozilla Firefox: This is a free and open-source web browser. Its source code is publicly available, and anyone can inspect, modify, and distribute it.

• GIMP: Standing for GNU Image Manipulation Program, GIMP is a free and open-source image editor. It's often seen as a free alternative to Adobe Photoshop.

• GNU/Linux: This is a family of free and open-source operating systems. The most well-known examples are distributions like Ubuntu, Fedora, and Debian. The source code for the kernel (Linux) and the system utilities (GNU) is freely available.

• MS Office: This is proprietary software developed and sold by Microsoft. The source code is not publicly available, and users must purchase a license to use it.
