UDP is a lightweight protocol that is used when the reliability of TCP is unnecessary. It is useful for applications that do not require the transfer of large amounts of data or where the loss of packets is not critical. DNS and DHCP can use both UDP and TCP, but UDP is generally preferred for its lower overhead. TCP, on the other hand, provides reliable, ordered, and error-checked delivery of data and is best suited for applications where data loss is unacceptable.
