Izinzwa, njengetshe legumbi lobuchwepheshe besimanje bolwazi, ziyibhuloho phakathi komhlaba obonakalayo nomhlaba wedijithali. Bangakwazi ukuzwa futhi baguqule amanani ahlukahlukene aphathekayo, njengezinga lokushisa, ukucindezela, ukukhanya, umsindo, ukugudluka, njll., ukuze banikeze okokufaka kwedatha okunembile kusistimu. Ku-automation yezimboni, ikhaya elihlakaniphile, impilo yezokwelapha, ukuqapha imvelo kanye neminye imikhakha eminingi, izinzwa zidlala indima engenakushintshwa. Ngokuqapha kwesikhathi sangempela nesilinganiso esinembile, izinzwa zisiza okokusebenza ukuzuza ukulawula okuhlakaniphile, ukuthuthukisa izinqubo zokukhiqiza, ukuthuthukisa ikhwalithi yokuphila, nokuvikela indawo ezungezile. Ngokuthuthuka okusheshayo kobuchwepheshe be-inthanethi Yezinto, ukubaluleka kwezinzwa njengengxenye ephambili yokutholwa kwedatha sekuvele kwagqama kakhulu, futhi sekuyisici esibalulekile sokukhuthaza inqubo yobuhlakani bomphakathi.
