WebbBecause of these capabilities, TCP is an excellent candidate for the transport layer protocol in a client-server architecture; hence, it was selected for use in this software. TCP is required because the features described in the question entail the client sending data to the server and the server sending a response back. Webb5 apr. 2024 · The TCP model can store broken packets instead of destroying them, and when fresh data packets are transmitted, these stored packets can fill in the gaps. This reduces latency and makes the connection more efficient. 2. Avoid well known or registered numbers for outbound and inbound port management
