1.Digital Assistant yog dab tsi?
Tus neeg pabcuam digital tus kheej, feem ntau hu ua PDA, yog ib qho khoom siv lossis software thov tsim los pab tib neeg nrog ntau yam haujlwm thiab kev ua ub no. PDAs feem ntau yog nruab nrog cov yam ntxwv xws li kev tswj hwm daim ntawv teev npe, kev sib cuag nrog lub koom haum, sau ntawv, thiab txawm tias lub suab lees paub.
PDAs pab cov tib neeg nyob ruaj khov thiab ua tau zoo los ntawm kev nqa cov cuab yeej tseem ceeb rau hauv ib qho khoom siv compact. Lawv tuaj yeem siv los tswj cov sijhawm teem sijhawm, teeb tsa kev ceeb toom, khaws cov ntaub ntawv tseem ceeb, thiab txawm tias ua haujlwm xws li hu xov tooj, xa lus, thiab nkag mus hauv is taws nem.
Nrog kev nce qib hauv thev naus laus zis, PDAs tau hloov kho kom suav nrog cov pab cuam virtual, xws li Siri, Alexa, lossis Google Assistant. Cov pab cuam virtual no tso siab rau kev txawj ntse txawj ntse thiab kev ua lus zoo los muab kev pabcuam tus kheej, teb cov lus nug, ua haujlwm, thiab muab cov lus qhia raws li cov neeg siv nyiam thiab tus cwj pwm.
Txawm hais tias nyob rau hauv daim ntawv ntawm cov cuab yeej siv lub cev lossis daim ntawv thov software, tus pab cuam tus kheej yog tsim los ua kom yooj yim thiab ua kom yooj yim rau kev ua haujlwm txhua hnub, ua kom muaj txiaj ntsig, thiab txhim kho tag nrho cov khoom tsim tau.
2.PDA Nta:
