It guarantees that the system sends only ordered, non-duplicated, and complete information to the top-layer application. TCP is a secure information transfer protocol because of its acknowledgments. UDP is generally used on protocols where a few lost datagrams don’t matter. This means TCP tracks all transmitted data and usually requires acknowledgment per byte. TCP is a linked protocol, while UDP is connection-free.TCP assigns an acknowledgment number to each segment, whereas UDP does not use an acknowledgment number for datagrams.Since there is no window mechanism in UDP, it does not support the retransmission of the datagram. In TCP, retransmission of the segment occurs through the window mechanism.TCP provides reliable services, while UDP does not offer reliable services.TCP provides a flow control service to handle the receiving data’s overflow, while UDP does not provide a flow control service.While UDP does not use sequence numbers to number the packets, it isn’t easy. So that at the receiver site, data can be collected sequentially using sequence numbers.
