[EN] TCP: The Engineering of Reliability and Flow Control on the Internet The functioning of the modern internet depends on a basic but extremely difficult premise to execute: reliability. When you download a file, send an email, or load a web page, every bit of information must reach its destination exactly as it was sent, in the correct order and without loss. The one responsible for this invisible feat is the Transmission Control Protocol or simply TCP. While the IP Protocol (Internet Protocol) handles addressing and routing, functioning like the system of streets and avenues, TCP is the express delivery service that ensures each packet not only arrives but is signed and checked. Without TCP, the world wide web would be a chaotic flow of fragmented data, where images would arrive scrambled and documents would have paragraphs out of place.
