Is it essential to install an operating system in a computer? Are software's included in OS?

Answer 1

You can use a computer without installing an operating system on it itself.
Instead you install the operating system on a bootable USB drive.
To do that you can use Rufus.

Rufus is a small utility, which can format and create bootable USB flash drives, such as USB keys or pen drives, and memory sticks. Rufus is useful in the following scenarios: If you need to create USB installation media from bootable ISOs for Windows, Linux, and UEFI. If you need to work on a system without an OS installed.

Answer 2

DOS, stands for disc operating system.
but I think
Machine language, is the only way you can interact with a computer that does not have an operating system.

ron I agree Rufus is a good utility. It makes any computer usable without an operating system or a working HDD.

Answer 4

Operating system act as an interface between you (user) and computer hardware.Without operating system it is difficult to interact with your computer.And hence it is essential to install it in computer.

Answer 10

It isn’t essential but it makes your life easier. Otherwise you’d be using a lot of machine code or assembly language for the low level hardware conversations. That would become exhausting for most people very quickly and most people would lose interest in computers because they wouldn’t know how to make their computer do stuff.

The best alternative to not using a popular OS is to using a less common one and improve it yourself OR make your own OS which would be almost the same as improving an unpopular one, just with more initial work. In any case, interesting question.
