Writing your own Operating System

• Writing your own operating is the most tedious programming task. You have to build software from the scratch.
• Starting Process of Computer. The Main board has special program called BIOS.
• Operating System Kernel Development Steps. As the first step let’s create four files.
• Kernel.cpp.

How an operating system is made?

Operating systems allow people to interact with computer hardware; they’re made out of hundreds of thousands of lines of code. They are usually made with C#, C, C++, and assembly. Operating systems allow you to navigate through a computer while creating storage and executing commands.

What language are operating systems written in?

Mac OS X: Cocoa mostly in Objective-C. Kernel written in C, some parts in assembly. Windows: C, C++, C#. Some parts in assembler. Mac OS X uses large amounts of C++ inside some libraries, but it isn’t exposed as they’re afraid of the ABI breaking.
