What is the difference in data transmission delivery and reliability between TCP and UDP?
- 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.
- TCP requires the connection to be established before transmitting data. UDP transmits data at a higher rate without ensuring packet delivery.
- UDP sets up a connection between both devices before transmitting data. TCP uses the three-way handshake to transmit data with a reliable connection.
- UDP is used for multicast and broadcast communication. TCP is used for unicast communication and transmits data at a higher rate with error checking.
Answer(s): B
Explanation:
UDP speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party. As a result, UDP is beneficial in time- sensitive communications, including voice over IP (VoIP), domain name system (DNS) lookup, and video or audio playback.
