Request for Comments, a type of publication from the Internet engineering community that describes methods, behaviors, research, or innovations applicable to the working of the Internet. RFCs are the primary means for communicating information about Internet standards.
Acronym coined in 1969 by Steve Crocker for the earliest Internet protocol documents. Originally meant to be informal 'requests for comments' from researchers, but evolved into the formal standard-setting mechanism for Internet protocols.
Every time you browse the web, send an email, or stream a video, you're relying on protocols defined in RFCs - these humble documents with bureaucratic-sounding names literally govern how the entire Internet works. The first RFC, published in 1969, was about host software and began with an apologetic tone because Crocker thought he might be overstepping by writing it down!
