RFC - Lingo
Request for Comments
An RFC (Request for Comments) is an Internet formal document or standard that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature. Of those that are intended to become Internet standards, the final version of the RFC becomes the standard and no further comments or changes are permitted. Change can occur, however, through subsequent RFCs that supercede or elaborate on all or parts of previous RFCs.
Remote Function Call
An RFC (Remote Function Call) is an application program interface to R/3 applications from Systems, Application and Products in Data Processing, the German company that sells a coordinated set of applications and databases to Fortune 1000 companies. SAP customers who wish to write other applications that communicate with R/3 applications and databases can use the RFC interface to do so.
