Subsequently, one may also ask, why would you use UDP over TCP?
UDP can be used in applicationsthatrequire lossless data transmission when the applicationisconfigured to manage the process of retransmittinglostpackets and correctly arranging received packets. This approachcanhelp to improve the data transfer rate of largefilescompared to TCP.
Subsequently, question is, which is better TCP or UDP? UDP. Faster Speed – UDP VPNserviceoffers significantly greater speeds than TCP. Forthisreason it is the preferred protocol when streaming HD videosordownloading torrents/p2p . Lower Reliability – Onrareoccasions UDP can be less reliable that TCPVPNconnections as UDP does not guarantee the deliveryofpackets.
Secondly, what is difference between UDP and TCP?
TCP (Transmission Control Protocol) isconnectionoriented, whereas UDP (User Datagram Protocol)isconnection-less. This means that TCP tracks all datasent,requiring acknowledgment for each octet (generally). Becauseofacknowledgments, TCP is considered a reliable datatransferprotocol.
What are the advantages and disadvantages between TCP and UDP?
The main advantages for UDP arethatdatagram boundaries are respected, you can broadcast, and itisfast. The main disadvantage is unreliability andthereforecomplicated to program at the application level. TCPand UDPuse the same addressing scheme.
