What is the difference in data transmission delivery and reliability between TCP and UDP?
A.TCP transmits data at a higher rate and ensures packet delivery. UDP retransmits lost data to ensure applications receive the data on the remote end. B.UDP sets up a connection between both devices before transmitting data. TCP uses the three-way handshake to transmit data with a reliable connection. C.UDP is used for multicast and broadcast communication. TCP is used for unicast communication and transmits data at a higher rate with error checking. D.TCP requires the connection to be established before transmitting data. UDP transmits data at a higher rate without ensuring packet delivery.正确答案D
