Why do we need TCP and UDP?

Last Updated: 24th February, 2020

Both TCP and UDP are protocols used forsendingbits of data — known as packets — over theInternet.They both build on top of the Internet protocol. In otherwords,whether you are sending a packet via TCP orUDP, thatpacket is sent to an IP address.

Thereof, 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.

Furthermore, 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.

Besides, 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.

Is YouTube a TCP or UDP?

Youtube uses TCP to control messagesratherthan UDP because of many reason If we use UDPwe mightget better performance than TCP but UDP willloosemany chunks of packet while streaming due to the lossy natureofInternet communications .

Why is UDP needed?

UDP has the capability of adding the portaddressto IP. Reasons for using UDP: UDP reducesoverheadbecause it does not add flow control, error control, orsequencedelivery unlike connection-oriented services. UDP isusedfor the transmission of data in which delivery of the data ismoreimportant than accuracy.

Does Netflix use UDP?

For non real time video streaming, likeNetflix,Hulu, Youtube, etc. they just use TCP anddobuffering instead of UDP, since they don't careabout a fewseconds delay between the server and client. That said,one of themost popular video streaming protocols that is basedonUDP/IP is RTP.

Is http UDP or TCP?

HTTP uses TCP because the files,images,web pages which we get from the remote host should not bedroppedon the way and it should be delivered in order to theHTTPclient. HTTP could also use UDP butusually not, if aUDP packet containing the first part of aweb page is lost,then its not retransmitted.

What are the situations when UDP is preferred over TCP?

UDP can be multicasted to multiplehostswhereas TCP cannot do this at all. TCP ,dueto its connection establishing and error checkingmechanismis considered a slow protocol (although reliable). WhileUDPdoes not have all those time consuming mechanisms and soit is muchfaster, not reliable but fast.
