Detailed explanation-1: -The main difference between TCP (transmission control protocol) and UDP (user datagram protocol) is that TCP is a connection-based protocol and UDP is connectionless. While TCP is more reliable, it transfers data more slowly. UDP is less reliable but works more quickly.
Detailed explanation-2: -True or False: UDP is more reliable than TCP because it is connection oriented communications. The correct answer is ‘False’.
Detailed explanation-3: -UDP does not provide error correction and is therefore an unreliable protocol. In other words, delivery of packets is not guaranteed. UDP datagrams are transmitted without provision for an acknowledgment. Because there is no virtual connection between sender and receiver, UDP is also said to be connectionless.
Detailed explanation-4: -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.
