Ifuro ry'icyuma ni ibikoresho bidasanzwe bigizwe n'ibikoresho byo mu kirere. Ukurikije imiterere yihariye yuburyo, ibyuma bifata ifuro bifite urukurikirane rwibyiza byiza nkubucucike buke ugereranije, kurwanya umuriro mwiza, urusaku rwiza no kugabanya amajwi kandi birashobora gusya no gukurura imiraba ya radio, nibindi. Ni icyiciro gishya cyibikoresho buhoro buhoro Itezimbere hamwe niterambere ryiterambere ryabantu ryikoranabuhanga rikoreshwa cyane mukirere, ibikoresho bya peteroli hamwe nuruhererekane rwo guteza imbere umusaruro winganda.

Ubwoba
Umubyigano ni igipimo cyubunini bwibintu byose byimiterere yumubiri wububiko hamwe nubunini bwuzuye bwimiterere yimiterere yumubiri, akenshi urebye ubunini bwumwanya uhuza intera yumubiri.
Ubwinshi bwibyuma bifata ibyuma bigera kuri 90%, kandi bifite imbaraga zo guhonyora hamwe no kugonda ubukana bwibikoresho byububiko. Ubu bwoko bwicyuma bufite ububobere buke, kandi diameter ya porosity igera kuri mm urwego.
