  "description": "TCP/IP is the foundational protocol suite of the Internet, enabling reliable, end-to-end communication across heterogeneous networks. TCP (RFC 793, 1981) provides reliable, ordered, error-checked byte-stream delivery using acknowledgments, retransmission, and congestion control. IP (RFC 791, 1981) handles addressing and routing — delivering individual packets (datagrams) from source to destination across an internetwork of networks. Standardized by Jon Postel at the IETF in 1980-1981, TCP/IP has scaled from ARPANET's 4 nodes to powering over 5.5 billion Internet users as of 2026.",
