Role of Protocols Protocols are like human communication - we
construct sentences, use language, and transmit
signals.


Interoperability Without protocols, there is no interoperability
between systems.


Standards Organizations Internet Society, Internet Architecture Board, IETF
(Internet Engineering Task Force) creates RFCs
(Requests for Comments), and ICANN.


Zero-day Vulnerability Newly discovered vulnerabilities not yet
addressed by a patch.
