: TCP delivers data as a continuous stream, not as discrete packets. A client might send a partial message, or multiple messages glued together. Your server must buffer incoming bytes per client and only process/broadcast them when a newline ( \n ) delimiter is reached. 4. Step-by-Step Architecture of an Exam-Ready Server
