Answer:
Transmission Control Protocol (TCP)
Explanation:
On the network architecture for connecting to the internet, the output intended to be sent over the internet by an application are split into packets and pushed for delivery by one of two protocols; TCP or User Datagram Protocol
These protocols are also responsible for taking the messages contained in the packets for onward delivery to the relevant application via ports
However, TCP gathers and arranges the received packets in the correct order as the originally sent message as well as requesting the retransmission of packets that are damaged or lost from the sending server so as to include their payloads in order to complete the original message.
