What is the purpose of TCP?

In the digital age, where global communication is essential, the Transmission Control Protocol (TCP) plays a crucial role in ensuring seamless data transmission over the Internet. It is a foundational protocol that forms the backbone of modern networking, enabling devices across the world to exchange information reliably, efficiently, and securely. So, let’s break down its inner workings, significance, and impact on our daily online experiences.
