Igikoresho cyo kuzamura icyuma kitagira umwanda nigikoresho cyo guterura isuku kandi gikomeye cyashizweho muburyo bwihariye bwo gutwara mu buryo buhagaritse ibikoresho byinshi, akenshi ibiribwa cyangwa ibirungo, mugutunganya no gukora ibidukikije. Igizwe nuruhererekane rwibikoresho bidafite ibyuma cyangwa indobo zashyizwe kumurongo utagira iherezo cyangwa umukandara uzenguruka umurongo, ukazamura witonze ibikoresho kuva kurwego rwo hasi ukagera hejuru. Kubaka ibyuma bitagira umwanda bitanga igihe kirekire, kurwanya ruswa, no koroshya isuku, bigatuma biba byiza mubisabwa aho isuku yibanze. Ubu bwoko bwibikoresho bukoreshwa cyane mu nganda nko gutunganya ibiribwa, imiti, n’inganda zikora imiti aho gukora neza n’isuku ari ibintu byingenzi.
