TCP

TCP, or Transmission Control Protocol, is a system that ensures data sent over the internet arrives accurately between devices. Think of it as a reliable postal service: it breaks down information into small packets, sends them, and confirms each one was received correctly before sending the next. If a packet gets lost or damaged, TCP prompts a resend, maintaining data integrity. It manages the connection, makes sure everything arrives in order, and guarantees that the message is complete and accurate, enabling smooth and reliable communication between computers, phones, and servers.
