The only necessary software for a computer to operate is the operating system. Everything else is software that you want to do things with. Different people will want to do different things with their computer, so what one person needs might be of no relevance to another person. But without an operating system you cannot do anything, as all the applications need that to run. If all you have on your computer is an operating system, then there is not much you can do with it, as you will then want applications. Even a lot of the things that are shipped as part of the operating system, like text editors, are not needed for the computer to function. Some of these are known as utilities. So the operating system is the only necessary software, and after that it is whatever you want to be able to do with the computer that will determine what you deem to be necessary.
