Ntau tus neeg ruam tsis meej pem txog cov lus sau cov ntaub ntawv, pda, thiab lub davhlau ya nyob twg ntse. Qhov tseeb, tsis muaj ntau qhov sib txawv. Feem ntau, cov tshuab no yog siv rau kev sau cov ntaub ntawv, cov ntaub ntawv txheeb xyuas, thiab cov ntaub ntawv xa mus thiab kev sib txuas lus, pab cov neeg siv ua tiav qee cov ntaub ntawv, kev sib txuas lus, kev ua cov ntaub ntawv, kev them nyiaj thiab kev sau thiab lwm yam haujlwm. Qhov tseeb, peb kuj tuaj yeem hais tias pda, lub davhlau ya nyob twg ntse kuj tuaj yeem hais tias yog tus sau cov ntaub ntawv, thiab cov ntaub ntawv khaws cia yog ib lo lus dav dav rau ob. Nws tsuas yog txawv raws li kev ua haujlwm thiab lub sijhawm siv. Handheld davhlau ya nyob twg hais txog lub chaw ua haujlwm cov ntaub ntawv nrog WinCE, Android thiab lwm yam kev khiav haujlwm, nco, CPU, npo thiab keyboard, nrog cov ntaub ntawv xa mus thiab kev ua haujlwm, nws tus kheej roj teeb, thiab kev siv xov tooj ntawm tes. Feem ntau hais lus, cov ntaub ntawv khaws cia yog hais txog lub davhlau ya nyob twg nrog cov khoom siv barcode scanning, tab sis tsis yog txhua lub xov tooj ntawm tes nrog barcode scanning muaj nuj nqi hu ua cov ntaub ntawv sau. Lub operating system ntawm cov ntaub ntawv khaws cia yog feem ntau tsim los ntawm cov chaw tsim khoom. , Piv txwv li, handheld computers xws li POCKET PC thiab PALM nrog barcode scanning muaj nuj nqi tsis hu ua cov ntaub ntawv sau, thiab cov ntaub ntawv khaws cov ntaub ntawv kuj hu ua inventory machines. Terminal khoom siv computer. Nrog rau kev nrhiav tau ntawm lub sijhawm tiag tiag, tsis siv neeg cia, tso saib tam sim, tawm tswv yim sai, kev ua haujlwm tsis siv neeg, tsis siv neeg kis cov haujlwm. PDA, tseem hu ua handheld computer, yog cais raws li nws siv thiab muab faib ua industrial-qib PDA thiab cov neeg siv khoom PDA. Industrial PDAs feem ntau yog siv hauv kev lag luam. Feem ntau cov tshuab luam ntawv barcode, RFID nyeem ntawv, POS tshuab, thiab lwm yam tuaj yeem hu ua PDAs; Cov neeg siv khoom PDAs suav nrog ntau yam, cov xov tooj ntse, ntsiav tshuaj computers, handheld game consoles, thiab lwm yam. Nws tuaj yeem pom tau tias ntau zaus, tsis muaj qhov sib txawv ntawm cov lus no, thiab lawv muaj peev xwm xa mus rau cov cav tov nrog tib lub luag haujlwm lossis daim ntawv thov. Yog li, rau cov neeg siv feem ntau, lawv yuav tsum xaiv thiab sib txawv li cas? Feem ntau hais lus, cov ntaub ntawv khaws cov ntaub ntawv, cov khoom muag cov cav tov, thiab ntau tus ntiv tes barcode cov ntaub ntawv terminals feem ntau yog siv rau kev sau barcode thiab sau tus lej lej, feem ntau yog rau barcodes. Nrog rau qhov muaj koob meej ntawm QR cov lej, cov ntaub ntawv khaws cov ntaub ntawv thiab cov khoom lag luam tau maj mam sib xyaw ua haujlwm ntawm QR cov lej. PDAs thiab handheld terminals feem ntau xa mus rau cov tshuab hauv Android lossis WINCE cov cav tov. Cov tshuab no feem ntau muaj zog, tseem hu ua cov tshuab ntse. Nyob ntawm cov ntaub ntawv siv, lub functionality txawv heev. Muaj peev xwm muaj ib lossis ntau qhov haujlwm.
