What happens if a device does not receive a response during a TCP connection?

If the device does not receive a response during a TCP connection, a retransmission of the packet occurs according to the TCP algorithm. TCP uses timeouts and acknowledgments (ACK) to ensure reliable data delivery. If an acknowledgment is not received within the specified time, the packet is retransmitted.

If repeated attempts fail, the connection may be terminated, and the application will receive an error. Thus, TCP ensures reliability through delivery control and recovery in case of packet loss.
