Difference Between TCP, UDP and SCTP Protocols
In the realm of computer networking, different protocols play a vital role in facilitating the transmission of data across the internet. Three prominent protocols, TCP (Transmission Control Protocol), UDP (User Datagram Protocol), and SCTP (Stream Control Transmission Protocol), serve as the building blocks of modern network communication. Each of these protocols possesses distinct characteristics and caters to specific requirements, making them suitable for different applications. This article delves into a comprehensive comparison of TCP, UDP, and SCTP highlighting their strengths, weaknesses, and optimal use cases.
