If you mean, why have we chosen Linux as our base for the Katheer OS?? The short answer is that it is a base for most of the other operating systems in the market apart from MS Windows. We can not make Windows our base because it's not open and it's protected by too many ways especially the coding copyright.

In general, Linux is the default environment for most software developers and is a popular choice for embedded solutions. However, one of Linux's greatest strengths, and to some extent, its biggest challenge, is that it comes in so many favours and varieties, each well suited to a particular use case. Most of the top supercomputers in the world run on Linux. Many run a variation of this popular operating system from the smallest devices to the largest mainframes and supercomputers. The reasons for Linux's popularity depend on its usage; in some cases, it's the open-source aspect, and in others, it's the scale of device support and the spectrum of processors and platforms. Linux scales from small resource-constrained computers to the largest supercomputer. Its portable source runs on various processor architectures (Intel®, Arm, IBM PowerPC, etc.).
