Question

A software company is deploying an internal application that transfers large installation packages between servers. The developers require that every byte arrives intact and in order, with automatic retransmission of any lost segments and flow control to avoid overwhelming the receiver. Which transport-layer protocol should the application use, and why?

Accepted Answer

TCP, because it is connection-oriented and provides acknowledgments, sequencing, and retransmission of lost data

Answer

UDP, because it is connectionless and delivers data faster with lower overhead

Answer

UDP, because it guarantees in-order delivery through sequence numbers without a handshake

Answer

TCP, because it is connectionless and relies on the application to handle reordering
