RFC 793 (Transmission Control Protocol)

RFC 793 defines the Transmission Control Protocol (TCP), a core part of the internet’s communication system. TCP ensures reliable, ordered delivery of data between devices over a network. It manages establishing connections, breaking data into manageable packets, confirming receipt, and retransmitting lost information. TCP also handles flow control to prevent overload and maintains a connection until communication ends. Think of it as a reliable letter delivery service in the digital world, ensuring your messages arrive intact, in order, and without duplicates, even amidst network issues.
