Detailed explanation-1: -A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
Detailed explanation-2: -TCP vs UDP: Speed differences UDP is faster than TCP but is also more error-prone. The reason is that UDP doesn’t use such an acute checking of packets as TCP and employs a more continuous data flow. TCP sends its data in sequence, so it uses more flow control.
Detailed explanation-3: -TCP is-clearly-just as “fast” (in terms of latency) as UDP as long as no IP packets get lost. So what happens if IP packets do get lost? In UDP’s case, nothing happens. The receiver doesn’t receive the packet, and the loss does not affect latency.
Detailed explanation-4: -UDP packets are transmitted at a rate of 64 Kbps here, and 80-byte UDP packets are transmitted at a rate of 100 packets/sec, whereas 320-byte UDP packet share transmitted at a rate of only 25 packets/sec.
