Have you worked with UDP protocol?

Yes, the UDP (User Datagram Protocol) is a connectionless transport protocol used for transmitting data with minimal delay. Unlike TCP, UDP does not guarantee delivery, order, or integrity of packets, making it faster but less reliable.

It is used in cases where speed is important and data loss is acceptable, such as:

• Video conferencing and VoIP
• Online gaming
• Streaming video broadcasts
• DNS queries

In DevOps experience, UDP is useful for configuring network services, monitoring, working with logs, and setting up firewalls, where understanding the protocol's features is important for proper configuration and diagnostics.
