答

要通过网络(WiFi、电缆等)在两个设备之间建立连接，您需要编写 2 个软件:

To establish a connection between two devices over a network (WiFi, cable, etc...) you need to write 2 pieces of software:

1) 服务器:等待连接

1) A server: which waits for connections

2) 客户端:发起与服务器的连接

2) A client: which initiates a connection to the server

一旦客户端发起 TCP 连接，设备就会连接起来，您可以在它们之间发送数据和消息.

Once the client initiates a TCP connection then the devices are connected and you can send data and messages between them.
