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

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 […]

A diagram illustrating the TCP 3-way handshake between a Host and a Server. The steps include: Step-1 with Host sending SYN (Seq=x), Server receiving SYN; Step-2 with Server sending SYN ACK (Seq=x, ACK=x+1), Host receiving SYN ACK; and Step-3 with Host sending ACK (ACK=y+1), enabling data transfer with binary data shown.
