Q&A for How to Make a Computer Operating System

Only if you're willing to learn a lot. You will require a full understanding of at least assembly code, and the motivation to learn more. Building your own OS is not a small task.

Learn programming languages and concepts, and practice to become a very strong programmer.

That depends on the programming language you are using. It is recommended, however, to use an IDE, or Integrated Development Environment, to program your operating system, as IDEs have built-in tools and features to help make development easier. Not all IDEs support every language however, so you will want to specifically search for IDEs that support the language (or languages) you're using.

Getting an open source kernel is better than coding one if you are in uni or something because you're not having to start from scratch or pay for it since it is open source. However, coding one proves a higher knowledge in programming, which you might prefer.

You can, but they're both two different operating systems and it would require a great deal of programming experience and work. Thus, unless you're able to do the programming, don't try it.

Windows is an unstructured OS, not to mention it's not open source, adding functionality to Windows is a pretty tough task. While Android can be said to be a variant of Linux, a structured and open-source OS, adding functionality layers is easy, but too many layers result in bad user experience. Back to the question, It would certainly require you have extensive knowledge of Android (you can try cooking an Android rom) and insider-knowledge of how some core components of Windows work, so what do you get after merging these two OS, will it be structured or unstructured, to begin with? There's too much ambiguity!

It'd take months if not years to make an OS that works properly with plenty of functionality. There's no possible way you can cook up an operating system in a few weeks or days.

Yes, Someone has done that before. However, If you want people to actually use your OS don't use java. It not only will take much, much longer but it will also not be as good as an OS made from another coding language. So, you can, yes, but should you? Probably not.

You need a LOT of knowledge regarding assembly and a low-level language, such as C. You'll also need extensive knowledge on memory handling, and will need to be able to handle connections with devices and peripherals.

You can make the graphics yourself, and you can start anytime and in any place you want. All you need is some programming knowledge and some software to program it with. If you're not sure what to do, doing an online tutorial with such places as Code Academy or Khan Academy might help.

You should learn programming concepts in a language like Python, then move on to a low-level language like C++. After mastering that, learn Assemblyx86.

FORTRAN isn't an assembly language, it's another "high level" language. The assembly language you use depends on your target architecture. For example, you would need x64 (x86_64) for a 64-bit version of the x86 architecture. That would be ideal for a desktop OS. If you're looking to build an OS for embedded applications, similar to TI's RTOS, you'd want ARM or MIPS assembly to support the corresponding instruction set architecture.

No. Visual C++ is built on the .NET Framework, and .NET runs only on Windows.

No, there really are no sites like that. You can't really take shortcuts in this ordeal.

If you're extremely skilled at programming. Every programming language and operating system was created by somebody (or a group of people).

Yes, that was the whole concept of MINIX and GNU/Linux. But first, familiarize yourself with the complexity of the Linux system.

Yes, you can, but when it comes to the development of your OS, go with Linux on your computer/laptop.

See this article: How to Install Ubuntu on VirtualBox .

A low level language, such as C and Assembly, as it would run a lot faster than a high level language.

Yes, but you also need some knowledge of a low-level language such as C to write all the very low-level stuff on the OS.

You can, but it would be better to write it on another low-level language such as C.

These can only be used for websites, so unless you're building a web-based OS, no.

Operating systems are usually programmed using systems programming languages, like C and C++. A new systems programming language Rust is gaining ground however, due to better memory safety.

If you're coding in a language like C, you can tell your compiler (like GCC) to target each processor architecture. If you're coding in assembly language, then don't. Seriously, don't. Unless you only want your system to work on one architecture, don't use assembly language by itself. You can get away with making the bootloader using assembly, but not much else.

Python is an interpreted language. In order to create an operating system, primary components like the kernel cannot have any dependencies, and the python interpreter would be considered a dependency.

There is an open-source tool called Cosmos that allows you to code an operating system using .NET languages.

The GNU C Compiler (GCC) is commonly used, as well as its C++ counterpart (g++).

Windows is an operating system. It is made by Microsoft and uses the NT kernel.

Just a short time. "Hello, world!" programs are not OSes, they are just programs running in command line programs.
