When is UDP preferred to TCP?

  • when a client sends a segment to a server
  • when all the data must be fully received before any part of it is considered useful
  • when an application can tolerate some loss of data during transmission
  • when segments must arrive in a very specific sequence to be processed successfully

Explanation: UDP can be used when an application can tolerate some data loss. UDP is the preferred protocol for applications that provide voice or video that cannot tolerate delay.
