# Systems

A *system* is a collection of [modules](https://engine.place.technology/key-concepts/modules), [settings](https://engine.place.technology/key-concepts/settings) and basic metadata (name, description etc). They provide the main logical building blocks within Engine deployments.

Systems often represent physical spaces (such as a meeting room) but can also represent standalone items such as a digital signage endpoint or a non-physical system with information based inputs and outputs.
