Editing UDP Protocol (section)

== 2. Use Cases Where UDP is Preferred ==

UDP is ideal in scenarios where:
* Speed is more important than reliability
* The application can handle occasional data loss
* Low latency is critical

{| class="wikitable"
! Example Use Case !! Protocol / Port !! Why UDP is Suitable
|-
| Domain name lookups || DNS / 53 || Fast, small queries with retry logic handled by client
|-
| Voice calls || SIP / 5060, RTP || Prioritizes real-time delivery over perfect reliability
|-
| Live video || RTSP, custom UDP streams || Skipping frames is better than stalling
|-
| Online gaming || Varies || Low latency is more important than perfect accuracy
|-
| Time synchronization || NTP / 123 || Delays are more harmful than packet loss
|-
| Lightweight monitoring || SNMP / 161 || Periodic data, not mission-critical
|-
| Bootstrapping devices || TFTP / 69 || Simple protocol for controlled environments
