RPC, an acronym for Remote Procedure Call, refers to a communication protocol employed in distributed computing systems. It enables a computer program to execute code in a different address space or on another machine, as if it were a local procedure call. RPC allows developers to build distributed applications by providing a means for clients and servers to communicate seamlessly.
In RPC, a client program typically sends a request message to a server program, specifying a procedure to be executed. The server then performs the requested operation and sends a response message back to the client. This process is transparent to the client, as it appears as if the procedure is executed locally. RPC hides the complexities of remote communication, facilitating the development of distributed systems by abstracting the underlying networking details.
The RPC framework provides various functionalities, including parameter transmission between the client and server, marshalling and unmarshalling data, handling exceptions across different machines, and managing the synchronization and coordination of the distributed processes. It allows developers to design applications with a modular structure, where different components can be developed independently and accessed through well-defined interfaces.
Overall, RPC is a powerful mechanism that enables efficient communication and cooperation between distributed systems and allows developers to create complex, scalable, and reliable applications by utilizing the capabilities of remote procedure calls.
