Ib qho hluav taws xob hloov hluav taws xob yog ib qho cuab yeej siv los cuam tshuam qhov ntws ntawm electrons hauv ib lub voj voog.Cov keyboards yog cov khoom siv binary tseem ceeb: lawv yog tag nrho ntawm ("kaw") lossis tag nrho ("qhib").Muaj ntau ntau hom kev hloov pauv, thiab peb yuav tshawb txog qee yam ntawm cov hom no hauv tshooj no.

Ua raws li kev tshawb nrhiav thaj chaw qub ntawm cov thev naus laus zis digital raws li kev sib txuas ntawm cov neeg kho tshuab es tsis yog lub xeev lub rooj vag circuits, thiab kev nkag siab zoo txog kev hloov hom yog tsim nyog rau kev ua haujlwm.Kawm txog kev ua haujlwm ntawm kev hloov pauv hauv tib lub sijhawm uas koj kawm txog cov rooj vag logic hauv lub xeev ua rau ob lub ntsiab lus yooj yim dua rau kev nkag siab, thiab teeb tsa theem rau kev kawm paub ntxiv hauv Boolean algebra, lej tom qab digital logic circuits.

Hom kev hloov pauv yooj yim tshaj plaws yog hu ua kev tiv thaiv thaiv qhov twg ob lub tshuab hluav taws xob tau coj los sib cuag nrog ib leeg los ntawm kev txav ntawm ib qho kev ua haujlwm.Lwm cov keyboards yog qhov nyuaj dua, muaj cov hluav taws xob hluav taws xob tuaj yeem qhib lossis tawm nyob ntawm qee qhov kev txhawb nqa lub cev (xws li lub teeb lossis qhov chaw sib nqus) paub.Txawm li cas los xij, qhov kawg tso zis ntawm ib qho kev hloov pauv yuav yog (tsawg kawg) ib khub ntawm cov hlau txuas txuas uas yuav txuas nrog ua ke los ntawm kev hloov pauv qhov kev sib cuag nrog lub tshuab ("kaw"), lossis tsis txuas ua ke ("qhib") .

Cov keyboards xaiv tau ua haujlwm nrog lub pob qhov rooj lossis lub zog ntawm qee yam los xaiv ib qho ntawm ob lossis ntau txoj haujlwm.Zoo li cov keyboards xaiv tuaj yeem so hauv ib qho ntawm lawv txoj haujlwm lossis muaj lub caij nplooj ntoo hlav rov qab los rau kev ua haujlwm ib ntus.
