Isikrini seedrum, njengesixhobo esiphambili sokuhlela isikhululo sokuhambisa inkunkuma, sesinye sezona zinto zibalulekileyo kwizixhobo zokulungisa inkunkuma.
Kuqala ukusetyenziswa kumgca wenkqubo yokwahlula inkunkuma. I-roller seef isetyenziselwa ukwenza inkunkuma ngokwee-granularity
Izixhobo zokuhlela ezilungisiweyo ngoomatshini. Umphezulu wonke werola ubhobozwe ngemingxuma yobukhulu obahlukeneyo. Umzimba wesikrini ufakwe ngendlela egobileyo, kwaye izinto zingena kwirola.
Ukujikeleza okulula kunye nokujika ngaphakathi kwenza ukujika okujikelezayo, inkunkuma enobukhulu besuntswana incinci kunomngxuma wesihluzo ihluzwa kwi-under-seeve, kwaye ihlala emzimbeni wesihluzo.
Izinto ezingaphakathi ziba sisihluzo kwaye zikhutshwa ezantsi komqulu.
