WebOct 18, 2024 · As an example, to create a socket for TCP communication, you could instantiate a Socket as follows: Socket s = new Socket ( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); Once a socket is created, it can be bound to an address. Binding is optional for client sockets but necessary for server sockets. WebStream sockets provide the most reliable connection. Datagrams and raw sockets are unreliable because packets can be discarded or duplicated during transmission. This characteristic might be acceptable if the application does not require reliability or if the application implements reliability beyond the socket interface. Performance
