Ivyuma vy’imodoka bishobora gushirwa mu bwoko butatu hakurikijwe ingingo ngenderwako y’ugukora kwavyo: ivy’umuyagankuba, ivy’umuyagankuba{0}}, n’ivy’umuyagankuba. Ivyuma bikoreshwa n’umuyagankuba bikoresha umuyagankuba kugira ngo bivemwo umuyagankuba kugira ngo bikoreshe amakontakte; zifise imiterere yoroshe ariko igihe co gusubiza kigenda buhoro (nk’10-30ms). Ivyuma bikomeye-state relays bikoresha ibikoresho bifise ubushobozi bwo guhindura umuriro (nk’ivyo bita MOSFETs) kugira ngo bishike ku guhindura ata gukorana, n’ibihe vy’inyishu bishika ku rugero rwa microseconde, ariko ku giciro kinini. Ivyo bikoresho vy’ubuhinga bwa none bihuza ivyiza vy’ubwo bwoko bwompi kandi birabereye mu bihe vy’uguhindura incuro nyinshi.
Ivyuma bigenzura imodoka ni ibihimba nyamukuru mu buryo bwo kugenzura imodoka, birimwo uburyo bwo kugenzura n’uburyo bwo kugenzura. Ivyo bikoresho bikoresha ingingo ngenderwako y’ubuhinga bw’umuyagankuba kugira ngo bigenzure amashanyarazi manini n’amashanyarazi mato. Kubera ko ari kimwe mu bikoresho vy’ubuhinga bwa none bikoreshwa cane mu modoka, bikoreshwa cane mu bikoresho vy’imodoka nk’amatara y’imbere, ibikoresho vyo guhanagura, ibikoresho vyo gutangura, n’ibikoresho vyo gutuma umuyaga ugera mu nzu, kandi kw’isi yose bikenewe ibikoresho birenga miliyaridi 1.
Ivyuma bigenzura imodoka zo mu gihugu ahanini bishirwa mu mice ibiri bivanye n’ibinyabiziga bikoreshwamwo: kimwe ni ivyuma bikoreshwa mu gucungera imodoka z’i Buraya, ahanini bikoreshwa mu binyabiziga bikoresha ubuhinga bw’Ubudage n’Ubufaransa; ikindi ni amarelay akozwe mu modoka z’Abayapani, ahanini zikoreshwa mu modoka z’Abayapani.
