What is the difference in data transmission delivery and reliability between TCP and UDP?
A . UDP sets up a connection between both devices before transmitting data. TCP uses the three-way handshake to transmit data with a reliable connection.
B . 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.
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.

Answer: D
