Free and OpenSource Software (FOSS) is one of the greatest phonomenon in past few decades in the field of information technology. As per Wikipedia, "Anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software ...." FOSS software provides a full stack of building blocks based on which complex IT systems can be built. Linux (and its mobile derivative Android) is a great example of such software. The correct knowledge of opensource softwares can greatly help in reducing licencing cost and build a high quality and extendable system.
