Idivayisi yokufaka idatha iyisisetshenziswa sikagesi noma okokusebenza okusetshenziselwa ukufaka imininingwane kukhompuyutha noma enye into kagesi. Izibonelo zamadivayisi okufakwayo kwedatha zifaka amakhibhodi, amagundane, iziphedi zokuthintwa, ama-trackballs, izikena, amakhamera, imibhobho, namapeni okubhala. Lawa madivayisi avumela abasebenzisi ukuthi bafake ulwazi nemiyalo ohlelweni lwekhompiyutha noma idivayisi kagesi, okubavumela ukuthi bahlanganyele nohlelo futhi benze imisebenzi eyahlukene. Imishini yokufaka idatha iguqula ulwazi lokufakwayo lube amasiginali edijithali uhlelo lwekhompiyutha olungawacubungula futhi luwasebenzise ngezinjongo ezihlukahlukene.
