Is NTP UDP or TCP?

Understand the Problem

The question is asking about the transport protocol used by Network Time Protocol (NTP), specifically whether it operates over UDP or TCP. NTP is known for synchronizing the clocks of computer systems over packet-switched data networks and typically uses a particular protocol for this purpose.

More Information

NTP (Network Time Protocol) primarily uses UDP because it offers low networking overheads and minimizes service response latency.

Tips

A common mistake is assuming NTP uses TCP because it's more widely known; however, NTP uses UDP for efficiency.
