Episode 25: TCP vs. UDP — Connectionless and Connection-Oriented

This episode explains one of the most fundamental networking concepts tested on the A Plus exam: the difference between Transmission Control Protocol and User Datagram Protocol. We begin with TCP’s key features, such as reliable delivery, session establishment, and ordered packet sequencing. Then we contrast that with UDP’s speed-focused, connectionless nature, which allows for lower latency but less reliability.

We walk through common applications of both protocols, such as TCP for web browsing or email, and UDP for video streaming or voice over I P. Understanding when and why each protocol is used is a key part of interpreting real-world scenarios and answering situational exam questions. By the end of this episode, you’ll have a firm grasp of this comparison and how to recognize it quickly in test items. Brought to you by BareMetalCyber.com.
