The application that runs on the machine where the framebuffer is located (which is running the windowing system and applications that the user is remotely controlling) is called the server. & krfb; is the & kde; server for the Remote Frame Buffer protocol. & krdc; is the & kde; client for the Remote Frame Buffer protocol.
Kaugekraani puhvri protokollis nimetatakse rakendust, mis töötab masinas, mille taga istub kasutaja (ja millega on ühendatud kuvar, klaviatuur ning osutusseade), kliendiks. Rakendust aga, mis töötab masinas, kus asub ekraanipuhver (kus töötab aknasüstee ning rakendused, mida kasutaja eemalt juhib), nimetatakse serveriks. & krfb; on & kde; kaugekraani puhvri protokolli server. & krdc; on & kde; kaugekraani puhvri protokolli klient.
