KOS allows users to create and store databases using a combination of SQlite and the JDBI library (Java Database Interface). This article will go into depth on how to create and use databases within KOS.

The `SpawnService` within KOS is a service whose primary responsibility is to start/stop native programs. It preforms this function across the nodes of a device. All the programs started via the service are monitored by KOS and will be restarted using a back-off algorithm in the event they crash.

KOS comes packaged with a FUSE (File System in User Space) filesystem. This allows users to mount KABs directly into the local native filesystem.

A brief introduction to KABs, Kab types, and sections within KOS Studio.

Controllers are a cornerstone of KOS applications, and provide an easy way to interact with the backend via RESTful HTTP endpoints.

The ConfigService provides the user a simple way to configure various aspects of an application via the Configuration Viewer in KOS Studio.

When interacting with hardware in KOS, the Board serves as the basic building block. A Board is just a logical representation of a circuit board.

An Assembly is KOS's way of abstracting a collection of hardware into an atomic unit, which can be installed and uninstalled.
