Transmission Control Protocol (TCP)

Transmission Control Protocol (TCP) is one of the main protocols of the Internet Protocol Suite. It originated in the mid-1970s through research funded by the United States Department of Defense's Advanced Research Projects Agency (ARPA). It was developed by Vint Cerf and Bob Kahn, who are widely regarded as the 'fathers of the internet' for their work on the underlying architecture of modern digital communication.

TCP is not a 'product' in the traditional physical sense but rather an open-standard technical specification. It provides reliable, ordered, and error-checked delivery of a stream of octets between applications running on hosts communicating over an IP network. Major internet applications such as the World Wide Web, email, and file transfer rely on TCP to function.

As an open standard, the intellectual specification of TCP is managed by the Internet Engineering Task Force (IETF), a non-profit open standards organization. It is not owned by any single corporation but is maintained through global consensus to ensure interoperability across all computer hardware and software platforms produced worldwide.
