4 Megabyte OS Kolibri

It is a surprising things that it's size is only 4 MB that is 4 megabyte. Only 4 MB. I did not believe it first. But after downloading I found that it is not just a simple thing but also it has some powerful feature.

Yes, I am talking about “Kolibri” OS. It has a graphical user interface and many games and a lot of tools and softwares to do miscellaneous jobs.

What is the specialty of Kolibri?
The kernel of this OS has a speciality. It is monolithic preemptive kernel. This monolithic kernel is quite different than regular kernel. Main operating system run in kernel space on supervisor mode. The main differences withing other kernel is on 'system call'. It made a high lavel virtual interface to do personal jobs (Process management, memory management etc.) of OS. So OS runs of low configuration machine well.

Preemptivity is an interrupting system. In this system when more then on process start on machine, a context swing get start to work. It stop an active process and start other. This works on priority. That means there is no any dual process on the same time. Process start one by one. We will not understand the interval time between each process. Because our processors are very high speed. They can handle each process at same time in a high speed that man can not understand the difference. Context swing use processors high speed to perform every work that we thought that Kobri os support multitasking. But actually it don't do that.

CD Player in Kolibri system

Kolibri follow these two steps to perform. It can run on older PC for it's monolithic kernel and it use preemptive so we imagine it as multitasking.
