Your computer itself has many powerful machines and virtually the ability to do almost everything; So what is the need of OS? Without the operating system what is possible to run your computer? Let's examine the matter in detail
What is operating system?
Thinking back to the 1970s, when only computer programs were energized. At that time there was a need to program a computer for doing that particular work. Suppose you want to work with word processing to your computer so you can write a new book. Then your computer had to program for the word processing program. Again, if you want to play chess with computer after 1 month, then your machine will need to re-program the chess again. Again, if you want to save and view photos on your machine, you have to program them separately. With each program you can do a new job, but they all repeat the same work again and again. As each of your programs is different, each of them has the need to read a "key" on the keyboard, there is a need to store data in memory, there is a need to retrieve the data, and there is a need to show how the program is working. So whenever you write a new program, you have to add these same processes over and over again. So, if this basic function is created with a separate program and all the programs are run on that program, then it will not be necessary to add the same feature repeatedly to all programs.

Computer without OS?
The importance of the operating system on your computer machine has surely come to an end, now the question is what will your computer do without the operating system, how will it work? Is it possible to work? If a computer's operating system controls all the work, of course, then it is impossible to run a computer without the operating system, is not it?
But the previous computers were seen, they did not have any operating system. Although the machines were gigantic, they could run only one program at a time. Suppose you are using a computer to do one or more work, you really do not need an operating system. Suppose you only want to work in word processing software, then target your computer directly to this software program and you will not need operating system. Other software is designed to target the operating system and the kernel without targeting the computer.

Last word
Without operating system, your computer will only be able to do one thing at a time. At present, the computer completes one process at a time but the OS completes this process so that you can not understand when multitasking is done, the computer is working on one. So I have clearly understood now how a computer can be operated without the operating system.
