Guide to Build an Operating System From Scratch

Operating System : 
An Operating System acts as an intermediary between the computer hardware and the user of the computer. The main purpose of an operating system is to provide an environment for effective execution of an application program.

An Operating System manages the resources and services such as devices, processors and memory. Process management, Resource management, Storage management and Security are some of the important functionalities of an Operating System .

Basic Architecture of an Operating System

How To Build Your Own Operating System From Scratch ??

Step-1 :

There are three most important aspects to master prior to Operating System development. They are basics of computer science , basic programming and learning both high-level and low-level programming languages . Assembly languages or low-level languages are used to communicate directly with  CPU ( Central Processing Unit ) . Each type of CPU speaks a machine language and there is just one corresponding assembly language for each type of CPU. x86 is the most commonly used computer architecture and C is the most commonly used high-level programming language for the development of an Operating System .

For High-level languages ( Modern Languages )

• The C Programming Language by Kernighan and Ritchie .
• C++: The Complete Reference
• Python Programming : An Introduction to Computer Science .

Step-2 :

The very next step in the development of an Operating System is to complete OS development tutorials.
