Topic 1 · Question 84

What is the difference in data transmission delivery and reliability between TCP and UDP?

  • ATCP transmits data at a higher rate and ensures packet delivery. UDP retransmits lost data to ensure applications receive the data on the remote end.
  • BTCP requires the connection to be established before transmitting data. UDP transmits data at a higher rate without ensuring packet delivery. (correct answer)
  • CUDP sets up a connection between both devices before transmitting data. TCP uses the three-way handshake to transmit data with a reliable connection.
  • DUDP is used for multicast and broadcast communication. TCP is used for unicast communication and transmits data at a higher rate with error checking.
Reveal answer & explanation
Correct answer: B

The correct answer is B. Option B: TCP requires the connection to be established before transmitting data. UDP transmits data at a higher rate without ensuring packet delivery.
