Master User Datagram Protocol (UDP) With Our Exclusive 2025 Guide

By Asad Ijaz

The User Datagram Protocol (UDP) is a lightweight communication protocol optimized for low-latency, loss-tolerant data transmission, ideal for Internet applications. Paired with IP (UDP/IP), it sends datagrams—small data packets—alongside TCP, serving CCNA/CCNP learners in 2025 network design. User Datagram Protocol (UDP) Low Overhead vs Reliability UDP provides basic transport layer functions with lower bandwidth overhead
