TCP: Definition & Details

Transmission Control Protocol (TCP) stands as one of the foundational pillars of modern computer networking, facilitating reliable data transmission across interconnected systems. As a core component of the Internet Protocol Suite (TCP/IP), this protocol ensures that data packets arrive intact, in sequence, and without errors from sender to receiver. Understanding it is fundamental for anyone delving into computer networking or seeking insights into how the internet operates.

What is TCP?

TCP is a communication protocol that enables two devices to establish a connection and exchange streams of data. Unlike its counterpart, the User Datagram Protocol (UDP), TCP prioritizes reliability over speed. It achieves this by implementing mechanisms for error detection, packet reordering, and flow control.
