Kwikhompyutha yedeskithophu noma i-laptop ekuphumeni, Uhlobo C lumane luyisixhumi esibonakalayo, njengegobolondo, umsebenzi waso uncike kumaphrothokholi asekelwa ngaphakathi. Ezinye izixhumi zohlobo C zingashaja kuphela, ezinye zingadlulisa idatha kuphela, kanti ezinye zingashaja, ukudluliswa kwedatha, kanye nokukhishwa kwesiginali yevidiyo ngesikhathi esifanayo. Esibukweni ekugcineni kokukhipha, kuyafana nokuba nesixhumi esibonakalayo sohlobo C, okungafani nokuba nemisebenzi ehlukahlukene. Kodwa-ke, wonke amamonitha asebenzisa isixhumi esibonakalayo sohlobo C njengendawo yawo yokuthengisa angasekela ukufakwa kwesiginali yevidiyo kanye nokushaja okuphindiwe.
