TCP vs UDP Explained in Hindi | PUBG Behind Cover Death, Netflix Delay, QUIC

A detailed examination of the differences between the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) protocols, focusing on their impact in real-world operational scenarios. The content breaks down system design concepts using examples such as the latency experienced in online gaming like PUBG and the delayed delivery handling in video streaming services such as Netflix. The explanation addresses how packet loss handling, reliability versus speed trade-offs, and connection management influence user experience in different application types.

The analysis explores specific technical aspects, including head-of-line blocking and the design rationale behind newer protocols like QUIC, which underlies HTTP/3. This comparison aims to clarify why different backend engineering choices are made depending on whether an application prioritizes low latency for real-time communication or stream integrity for media delivery.
