Within the family of Internet Protocol (IP) protocols, UDP is a data transmission system. A link between two servers is not necessary for the transmission of datagrams using the connectionless algorithm UDP. UDP is used in circumstances like streaming media, online gameplay, and others where minimizing delay is more crucial than preventing data loss on occasion.

UDP is a straightforward method of sending data when compared to other data transmission methods like TCP, SFTP, and HTTPS. It is not necessary for the device transmitting the datagrams to create a link, check to see if each message has been received, and resend any information that was lost in transmission. Instead, it transmits as many datagrams as it can, each carrying the target IP address, transit details, and content. In comparison to other protocols, UDP has less delay and lag because it skips the connection and authentication phases.

There is no assurance that the gadget receiving the datagrams will actually receive all of them, though. The recipient device has no means to re-request the data if network gridlock results in some datagrams being lost. A reduced latency in the context of an Internet video conversation indicates that there is less of a lag between what is said on one end of the contact and what is heard on the other. The video may briefly stop before starting again if the link between the two endpoints becomes sluggish and some datagrams are dropped.
