1.Ikhadi lezithombe (Ikhadi levidiyo, ikhadi lezithombe) Igama eligcwele lekhadi lesibonisi, elibuye laziwe ngokuthi i-adaptha yokubonisa, liwukumiswa okuyisisekelo futhi esinye sezisekeli ezibaluleke kakhulu zekhompyutha.
Njengengxenye ebalulekile yosokhaya wekhompuyutha, ikhadi lezithombe liyidivayisi yokwenza ukuguqulwa kwesignali yedijithali-kuya-analogi, futhi lenza umsebenzi wokukhipha nokubonisa ihluzo;
 

I-2.Imonitha iyidivayisi ye-I/O okungeyekhompuyutha, okungukuthi, idivayisi yokufaka nokukhiphayo.Kuyithuluzi lokubonisa elibonisa amafayela athile e-elekthronikhi esibukweni ngomshini othile wokudlulisa bese liwabonisa esweni lomuntu.Isibonisi siyidivayisi nje yokubonisa futhi ayihlanganyeli ekucubunguleni nasekuguquleni idatha;
 
3.Ikhwalithi yekhadi lehluzo lizothinta ngokuqondile ukukhishwa kwesibonisi sokuqapha, futhi ukwehluleka kwekhadi lehluzo kuzoholela esikrinini esibi, isikrini esiluhlaza okwesibhakabhaka, isikrini esimnyama nezinye izimo ezimbi;
 
4.Ikhadi lezithombe lihlobene nesinqumo kanye nesikhathi sokuphendula sesibonisi;ikhadi lehluzo elisezingeni eliphezulu lifakwe ukuqapha okuphezulu;ikhadi lezithombe ezisezingeni eliphezulu likhipha ukulungiswa okuphezulu uma kuqhathaniswa;
 
5. Izinga lekhadi lezithombe lithinta isivinini, ukudluliswa kanye nemisebenzi yokucubungula yekhadi lezithombe ukuze kucutshungulwe izithombe, futhi isikrini sokubonisa sisetshenziswa kuphela njengedivayisi yokukhipha isibonisi.
