| # 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. |
