Tus kws pab cuam tus kheej (PDA) yog ib lub xov tooj ntawm tes siv rau kev ua haujlwm ntawm tus kheej lossis kev lag luam xws li teem sijhawm thiab khaws daim ntawv qhia hnub thiab cov ntaub ntawv chaw nyob. Smartphones tswj cov haujlwm no, ib yam nkaus, los ntawm kev ua haujlwm ua haujlwm lossis cov apps. Kab lus no saib qhov sib txawv ntawm PDAs thiab smartphones los pab koj txiav txim siab qhov twg yog qhov zoo tshaj rau koj.
Kev Tshawb Nrhiav Txhua Yam
- Nqis dua li smartphones.
- Lack the connectivity range of a smartphone.
- Yuav ua tau Wi-Fi enabled.
- Tsis xav tau tus cab kuj wireless.
- npo loj dua qee lub xov tooj smartphones.
- Kev txhawb nqa cov chaw tsim khoom tau poob qis.
- Ntau dua li PDAs dhau lub neej ntawm lub cuab yeej.
- Xav tau txoj kev npaj cov ntaub ntawv wireless.
- Tied rau lub wireless cab kuj lub network.
- Yooj yim heev.
- Apps muaj nyob rau txhua txoj haujlwm hauv qab hnub.
- Yuav txhawb nqa thiab kho dua tshiab rau xyoo tom ntej.
Smartphones nyob txhua qhov chaw, thiab ntau tus neeg siv tso siab rau cov khoom siv no ntau dua li kev sib txuas lus suab thiab ntawv. Txawm li cas los xij, PDA tseem nyob ib puag ncig, thiab qee cov neeg siv txaus siab rau nws cov phiaj xwm hnub digital-hom kev ua haujlwm.
Vim cov neeg siv PDA ntxov tshaj plaws yog cov neeg siv kev lag luam, software lag luam zoo muaj rau PDAs. Tseem, qhov ntau thiab kev sib raug zoo ntawm cov apps muaj rau smartphones yog qhov xav tsis thoob, thiab PDA hnub zoo tshaj plaws tshwm sim tom qab nws.
Vim li cas lawv hu ua Smartphones?
Price: PDAs raug pheej yig dua
- Tseem kim tag nrho.
- Ntau tus nqi muaj.
- Tus nqi tsis ntxiv raws sijhawm.
- nqi ib hlis ua rau tus nqi tiag tiag.
- Price vary.
- Tus nqi ntxiv raws sijhawm.
PDAs feem ntau pheej yig dua li lub xov tooj smartphone dhau lub neej ntawm lub cuab yeej, txawm hais tias thawj tus nqi yuav khoom ntawm qee lub xov tooj smartphones tsawg dua tus nqi ntawm PDA. Koj feem ntau them ntau dua rau lub xov tooj smartphone dhau ib lossis ob xyoos tshaj li qhov koj xav tau nrog PDA. Piv txwv li, wireless cov ntaub ntawv npaj them nqi ntxiv rau lub sijhawm, ua rau cov smartphones kim dua nyob rau lub sijhawm ntev.
Xav txog PDA uas raug nqi $ 300 thiab lub xov tooj qis qis uas raug nqi $ 150 ntxiv rau $ 40 ntxiv rau ib hlis rau kev pabcuam cov ntaub ntawv. Tom qab ib xyoos ntawm kev pabcuam, kev pabcuam smartphone thiab cov ntaub ntawv raug nqi $ 630.
Kev sib txuas: PDAs tsis txuas nrog
- Tsis txhob txuas rau cov xov tooj ntawm tes.
- Yuav siv tau kev sib txuas Wi-Fi.
- Yuav siv tau kev sib txuas Bluetooth.
- Cov phiaj xwm txhais tau tias cov xov tooj smartphones txuas nrog hauv internet.
- Yuav siv tau kev sib txuas Wi-Fi.
- Yuav siv tau kev sib txuas Bluetooth.
Nrog txoj kev npaj cov ntaub ntawv wireless, smartphones ib txwm txuas nrog Is Taws Nem. Mus online txhua lub sijhawm thiab nyob qhov twg koj muaj kev pabcuam. PDAs tsis txuas rau cov xov tooj ntawm tes thiab tsis tuaj yeem muab tib yam kev sib txuas uas cov xov tooj smartphones muab.
PDAs thiab smartphones kuj siv lwm hom kev sib txuas, suav nrog Wi-nkaus thiab Bluetooth. Nrog rau Wi-Fi-enabled PDA lossis smartphone, piv txwv li, nthwv dej hauv internet, tshawb xyuas email, thiab rub tawm cov ntaub ntawv txhua qhov chaw muaj Wi-Fi hotspot, feem ntau ntawm qhov nrawm dua nrog cov ntaub ntawv xov tooj ntawm tes.
Yog tias koj lub PDA lossis lub xov tooj smartphone muaj Wi-Fi, siv cov phiaj xwm hu xov tooj hauv internet xws li Skype txuas rau cov phooj ywg thiab tsev neeg.
Smartphones feem ntau yog khi rau lub wireless carrier's network, thaum PDAs yog cov neeg nqa khoom ywj pheej. Hloov cov chaw muab kev pabcuam tuaj yeem nyuaj rau cov tswv smartphone, thaum qhov no tsis yog teeb meem rau cov neeg siv PDA.
Functionality: Ib txhia nyiam ob yam khoom
- Qee tus neeg nyiam muaj ob lub cuab yeej.
- tuaj yeem ua daim ntawv qhia hnub thiab hu rau thaub qab yog tias koj lub xov tooj ploj.
- Cov xov tooj me me me yuav siv tau yooj yim.
- Lub xov tooj siv tsis tau tso koj yam tsis muaj koj cov neeg tiv tauj thiab daim ntawv qhia hnub.
Txawm hais tias ntau tus neeg siv tau tso PDAs los ntawm txoj kev hauv kev pom zoo ntawm cov smartphones puv, qee cov neeg siv nyiam cov haujlwm uas ob lub cuab yeej muab. Piv txwv li, PDA tuaj yeem muab lub vijtsam loj dua li qee lub xov tooj smartphones, uas yuav pab tau rau cov neeg siv uas xav tshuaj xyuas cov ntawv nthuav tawm lossis lwm cov ntaub ntawv yam tsis muaj scrolling ntau dhau. Nco thiab ua lub zog kuj tuaj yeem sib txawv ntawm cov khoom siv.
Yog tias lub xov tooj smartphone tawg lossis ploj lossis raug nyiag lawm, cov ntaub ntawv khaws cia ntawm nws yuav ploj mus yog tias koj tsis muaj cov ntaub ntawv thaub qab kom raug. Yog tias koj muaj PDA, cov ntaub ntawv tiv tauj tuaj yeem nkag tau yooj yim txawm tias koj lub xov tooj siv tsis tau.
Kev Txiav Txim Kawg
Qee tus neeg nyiam lawv cov PDAs, nrhiav lawv los ua cov cuab yeej zoo hauv kev koom nrog, sau ntawv, khaws cov xov tooj, tswj cov npe yuav tsum ua, txaus siab rau kev lom zem, thiab taug qab daim ntawv qhia hnub.
Qhov tseeb yog qhov kev txhim kho PDA tau los nres, thiab tej zaum yuav muaj teeb meem ntawm lub sijhawm kom txog thaum PDA tsuas yog nco.
Smartphones, nrog kev sib txuas ntawm is taws nem thiab Wi-nkaus nkag nrog rau kev sib txuas lus ntawm tes thiab ntau yam apps, tsis mus qhov twg los tau sai sai no.
