Izinzuzo: Ukucabanga kwezicatshulwa zokuphendula kwekophu ngesiphumo sokubheka sokuqala esiqinileyo, ngokwesibhedlela sokuthi kusukelele umphako wesikhatsi. Lokhu kulungiselela uphawu olukhothayo lokutsibakalelwa ngokuhluke kunesikhatsi sesikhatsi.
Amazwanyana: Kungaphandle kokuthi kube kudala ngokwesihloko esisodwa kwekophu okanye esikhatsi, umsebenzi wokusukelela kungaphansi kwalokhu nokuthi kungabafundi abaningi.
Amalindlela Amacayishoni: Kusetyenziswa kwiqhapha lezindlela ezikhulu, imakhineyi yelektri, kunye nomthengi wampefumulo apho kubiza ukuphawuleka kwamandla.
