System (Latin systēma) is a group of related things that work together as a whole. These things can be real or imaginary. Systems can be things like a car's engine. But systems can also be concepts made by people to organize ideas. A subsystem is a little system within a big system.
What systems do[change | change source]
Systems are a way to describe a set of items, or people, or things that are related. Most systems describe ways of making them work together, or why they work together already. Some systems are nothing more than a different way of looking at a problem, or thinking about a job being done.
Other systems are more like organizing books on a shelf, so that people can find things more simply, without having to search. These can be systems about how to program computers or manage people.
