Os!!

[Baladiscovery]

I have read many things about developing a operating system and I have many doubts in it and I think I guys can help me out!!! The first one:In which I can create or develop a os! Second one:what is shell and api!! Many are there now these two are more confusing !! Please help me !! 

 

Thank you

maybe use linux as a base?

what? in which what can you create an os? which program? which computersystem?? could you clarify?

1) Linux and Apple OS is written in C. Windows is C++, I believe (do correct me if I'm wrong). You just need a program to write the code. Technically it can be done in notepad.exe if you're very hardcore.

2) Shell is a blanket term for a way of controlling and managing OS settings. For instance the Windows Command prompt is a shell. The Windows Control Panel is a shell too. But most commonly we mean the text-based tool by shell.

API (application programming interface) is a set of software tools that I as a system developer would grant you so that you could develop programs for the system I'm managing. I wouldn't give you universal access to my source code but pre-compiled commands that are easier for you to utilize. So by using the API, lest say DirectX, the game developers don't have to have perfect knowledge of the inner workings of a specific GPU, let alone all of them.

Developing an OS is a massive task. Given all the things you need to get working correctly before you can do something as "simple" as interface with a shell (I'll get to that in a paragraph or two later). Companies like Apple, Microsoft, and Canonical (the guys responsible for maintaining Ubuntu) dedicate massive teams and months or years to creating their operating systems, and they've already got a good base to start.

 

Even in my operating systems class in College, we didn't attempt to make an operating system, we only simulated portions of it to get a feel for design decisions. (If you are looking for a book to get started, we used Operating Systems Concepts, by Abraham Silberschatz).

 

A shell is the collection of programs that let a user interact with the kernel. If an OS was a car, the door, steering wheel, and pedals (gas and brake) would be the shell; they let the user access other functions in the "shell" and interact with the engine, wheels, and brakes, which in this case, represents the kernel.

 

Honestly, the best place to start would be to familiarize yourself with a flavor of Linux, like Ubuntu, Mint, or Debian (I'd recommend running them as a virtual machine, like VirtualBox). Once you feel comfortable running those, you can try Arch Linux. You have to compile Arch Linux yourself, but you have massive amounts of control over how things work, and you can learn a lot about Linux and operating systems that way.

Am asking which program !!

Dude.... If you don't know what a shell or API is, you're not going to be able to make an OS. They are ridiculously complicated and difficult to make, I wouldn't try it. Start small. What's your programing background?

Dude I know both but it's a bit confusing and all definintion on internet are confusing so..! Thank you

The grammar nazi in me is annoyed at the title, it should be 'develop an OS'. And it's not technically wrong but some extra context wouldn't go amiss.

Now it's ok?

Much better, thanks. On the subject of your thread, unless you have a team of programmers and a lot of money, don't try.

Ok ok thank you so much !! Is collection of api's makes a part of os ?!?!?

have a look at linux from scratch. http://linuxfromscratch.org/lfs/

What is Linux From Scratch?

Linux From Scratch (LFS) is a project that provides you with step-by-step instructions for building your own customized Linux system entirely from source

 

[Baladiscovery]

What about visual studio !?!? Or visual c++ I saw in many websites that It can be used !! What you guys say!?

Sure will look into it and thanks for your replay !!

[Baladiscovery]

Is collection of software makes a os ?!?!

can visual studio can be used to develop a os !?!?

[Akolyte]

You can develop an operating system using Visual Studio as an IDE.  So yes, you can write an operating system using Visual Studio, just don't expect it to be easy haha.

Then which project I should choose for creation of os !!!!!? I know to use visual studio but many doubt pls help me !?!?

Well, writing an OS can be quite difficult, if you do it from scratch.  You have to write the kernel which handled memory management, drivers etc and then you have to write a CLI (command line interface) on top of that.  There are some frameworks out there to help you to write a very basic operating system;  

 

but to be totally honest, first of all you want to know how to use Linux and familiarize yourself with it, and then I would probably look up how to create or modify a distribution.  That would be the first steps in my opinion, it really depends and is up to you.   

 

Don't let people doubt you, but don't say you can write an operating system.  But know that if you work hard and diligently you can do almost anything.

But I asked about visual studio !! 

Then you are suggesting Linux ahh?

 

[kerradeph]

Because realistically, you're not going to take on making an entire operating system as your starter project. Creating a Linux variant first would be where you would want to start. 

 

What were you expecting this OS to look like? Considering you asking specifically for visual studio, i don't know if you quite understand the size of the project you are asking about.

1. What many universities use to teach operating systems; costs money but will teach you ALOT about operating systems; Minix is not as usable as linux but please get this book:

https://www.amazon.com/Operating-Systems-Design-Implementation-3rd/dp/0131429388/ref=sr_1_1?s=books&ie=UTF8&qid=1478671672&sr=1-1&keywords=Operating+Systems%3A+Design+and+Implementation+3%2Fe+by+Andrew+S.+Tanenbaum

2. I think ive already told you this; look at linux from scratch; teaches you to compile linux which means you will be able to create a useful operating system; it is free:
