When it comes to Linux, most of the things that are there in the OS are written in C programming language, and assembly language also plays an important role in the Linux architecture. As already mentioned, it uses a MMU, for both paging (not to disk yet) and segmentation.” It uses every conceivable feature of the 386 I could find, as it was also a project to teach me about the 386. “It's mostly in C, but most people wouldn't call what I write C. Linux Torvalds (Founder of Linux) has this to say about − In order to take a look and understand what different languages these operating systems use and why they use those particular languages only, we need to visit the official comments of such operating system developers.

It should also be noted that a major part of any operating system is the kernel and the kernel is different for each of the operating systems, like we have a different kernel in Windows which is developed using a different programming language, as when compared to a kernel of Mac OS. The most notable difference one can notice is how they store the files in their file structure, like in case of windows, it follows a directory structure to store the different kinds of files of the user, whereas the Mac OS file structure is known as MAC OS X and when it comes to Linux the file structure is entirely different from Windows and Mac as it stores the data in the form a tree.Īnother major difference is the tech stack that these languages were built upon, the programming languages that played a major key role in their development and deployment. While there are cases where one might outperform another, those cases and such scenarios are very rare.

The three most common and widely used operating systems share things in common just as well they share the differences. We know that an operating system is considered as the backbone of any system that you may use.
