It's fine to not know what an operating system is. There are lots of areas of life where I'm almost totally ignorant. The difference is I wouldn't try to report on them before I learned very basic, elementary things about them. It's not too much to expect someone to learn "it's like Android or iOS" before professionally writing about it.
