Do you have practical experience in implementing interaction between network components or systems?

Yes, in C#, interaction between network components often uses sockets (System.Net.Sockets) or higher-level abstractions, such as HTTP clients (HttpClient) for REST APIs. Here's an example of a simple TCP server and client:

// TCP server
var listener = new TcpListener(IPAddress.Any, 5000);
listener.Start();
var client = listener.AcceptTcpClient();
using var stream = client.GetStream();
// reading/writing data

// TCP client
var client = new TcpClient("localhost", 5000);
using var stream = client.GetStream();
// sending/receiving data

Protocols for message exchange, such as RabbitMQ, gRPC, or WebSocket, are also commonly used for bidirectional communication. Interaction can be synchronous or asynchronous, depending on performance and reliability requirements.
