Summary

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are the two primary methods for data transport on the internet, each with distinct characteristics and use cases. TCP is known for its reliability and accuracy, making it suitable for tasks requiring error-free data transfer, such as web browsing, email, and file downloads, due to its use of handshakes and acknowledgments to ensure data integrity. In contrast, UDP prioritizes speed and is favored in scenarios where rapid data delivery is crucial, such as live streaming, online gaming, and DNS queries, as it sends data in quick succession without verifying order or completeness. While TCP tends to be slower due to its focus on accuracy, advancements like TCP Fast Open and Multipath TCP are mitigating latency issues. UDP is not limited to streaming and gaming; it also supports applications like low-latency trading and sensor technologies. Modern applications often employ both protocols, utilizing TCP for initial connections and metadata, while relying on UDP for real-time data streaming. Choosing between TCP and UDP depends on the specific needs of the application, with TCP being ideal for tasks requiring stability and reliability, and UDP being better suited for those prioritizing speed and low latency.
