Drivers
Drivers provide software interfaces for communicating with hardware (or virtual) devices that are embedded in or connected to a system. In Fuchsia, drivers are user-space [components][components]. Like any other Fuchsia component, a driver is software that exposes and receives FIDL capabilities to and from other components in the system. Using these FIDL calls, Fuchsia components interact with drivers, which are bound to specific devices in the system.
Similar to Fuchsia’s component framework, which manages Fuchsia components, the [driver framework][driver-framework] manages the lifecycle and topology of all devices (known as [nodes][nodes]) and drivers in a Fuchsia system.
