Ebyuma ebifuuyira, era ebimanyiddwa nga ebyuma ebisiiga, kye kimu ku bikozesebwa eby’enjawulo ebikozesebwa okusiiga layers ez’obukuumi oba ez’okuyooyoota ku byuma n’ebitali-kyuma. Kigabanyizibwa mu bika bya manual, semi-automatic, ne fully automatic okusinziira ku ddaala lyayo ery'otoma. Omulimu gwa China ogw’okukola ebyuma ebifuuyira gwatandika oluvannyuma lw’ennongoosereza n’okuggulwawo. Olw’okukulaakulanya enkola y’amakolero mu ngeri ey’obwengula, layini z’okufulumya ebifuuyira kati zikozesebwa mu makolero g’emmotoka, ebyuma by’omu maka n’eby’omu bwengula.
Ebyuma ebifuuyira ebigezi bituuka ku kufuga obumu bw’okusiiga nga biyita mu nteekateeka y’enkola ey’otoma n’enkola z’emirimu ez’okukolagana, okutumbula ennyo obulungi bw’okuzimba. Mu kiseera kino, amakolero gali mu mutendera gwa tekinologiya ow’okuyingiza ebintu mu ggwanga, nga goolekedde ensonga ng’obusobozi obutamala mu kukola ebitundu ebikulu, era ebitundu ebikulu bikyasinziira ku biyingizibwa mu ggwanga.
