What is the main advantage of UDP?
What is the main advantage of UDP? Explanation: As UDP does not provide assurance of delivery of packet, reliability and other services, the overhead taken to provide these services is reduced in UDP’s operation. Thus, UDP provides low overhead, and higher speed.
Where is TCP and UDP used?
TCP – used for traffic that you need all the data for. i.e HTML, pictures, etc. UDP – used for traffic that doesn’t suffer much if a packet is dropped, i.e. video & voice streaming, some data channels of online games, etc.
