# RPC # RPC
This module implements communication between processes, including inter-process communication (IPC) on a single device and Remote Procedure Call (RPC) between processes of difference devices. IPC is implemented based on the Binder driver, and RPC is based on the software bus driver. The **RPC** module implements communication between processes, including inter-process communication (IPC) on a single device and Remote Procedure Call (RPC) between processes on difference devices. IPC is implemented based on the Binder driver, and RPC is based on the DSoftBus driver.
