Yintoni iPDA? Kungenzeka kakhulu ukuba ngamathuba athile ukhe weva okanye ufunde okuthile malunga neli gama, malunga nezi zishunqulelo. Kodwa usenokungacacelwa ncam yintoni okanye yintoni iPDA. Ngoko ke, ngezantsi siza kukuxelela yonke into omele uyazi malunga nesi sixhobo ukuze uphume ngaphandle kwamathandabuzo akho.
Siza kukuxelela ukuba yintoni iPDA, yeyantoni, kunye nemvelaphi yayo, ukuze sazi ngakumbi malunga nokuba sivela njani esi sixhobo. Kuninzi lwenu ngumbono oqhelekileyo, usenokuba wawukhe waba nawo kwixesha elidlulileyo. Nokuba imeko ithini na, uya kuba nako ukwazi ngakumbi ngale PDA.
Yintoni iPDA
I-PDA sisixhobo esincinci sombane, ngokuqhelekileyo ingena epokothweni kwaye inokubanjwa entendeni yesandla. Esi sixhobo sisetyenziselwa ukuba noluhlu lwabafowunelwa bobuqu, ikhalenda enamadinga, iintlanganiso okanye izikhumbuzo, kunye nemisebenzi efana nekhaltyhuleyitha, inkcazo kunye nespredishithi ezisoloko zikufuphi. Sisixhobo esiye sanyamalala kwimarike ngenxa yokunyuka kwee-smartphones, ngenxa yesi sizathu, abaninzi babona i-PDA njengemanduleli eefowuni eziphathwayo zangoku, ekubeni ezi fowuni zithathe njengesiseko imisebenzi yePDA, kwaye ziye zazisa kwakhona. ubuninzi beminye imisebenzi eyongezelelweyo.
I-PDA iphendula kwisishunqulelo ngesiNgesi, Uthetha ukuthini uMncedisi weDijithali woMntu, leyo ngesiSpanish sinokuyiguqulela njengoMncedisi weDijithali yoBuqu. Sisixhobo esasungulwa ngexesha laso ngokukhethekileyo kubantu abakwicandelo lezoshishino (abaphathi okanye abantu ababesebenza kwimarike yezabelo), ekubeni ngaloo ndlela benomncedisi wabo osoloko ekhona, epokothweni okanye kwibrifkheyisi. Enkosi kwesi sixhobo baya kukwazi ukubona ukuqeshwa kwabo, umzekelo, okanye ukufumana ngokulula iinkcukacha zoqhagamshelwano zomntu.
Historia
Njengoko unokucinga, sisixhobo esinendlela ethile kwimarike. Yingakho abaninzi sele beyazi ukuba yintoni iPDA, nangona imbali yesi sixhobo yinto engaziwayo kwabaninzi. Siye sakhankanya ukuba ezi zixhobo zingabanduleli beefowuni eziphathwayo zangoku, ngoko ke oku sele kusinika ingcamango malunga nexesha eliye ladlula ekubeni ziqaliswe kwiimarike.
I-PDA yaqala ukusasazwa kwayo emarikeni ekupheleni kwe 90. Brands ezifana HP, Sharp okanye Casio Basele benedayari ezithile ze-elektroniki kwimarike kwisiqingatha sokuqala se-90, le mizekelo ibonwa njengeyokuqala kusapho lwePDA. Nangona bekungekho kwisiqingatha sesibini saloo minyaka xa izixhobo zokuqala zolu hlobo zaqala ukuvela, izixhobo ziphelele ngakumbi ngokwemigaqo yemisebenzi, efana nePalm Inc (inkampani esandul 'ukudala nayo). Nangona kuqala ukusishiya ngokupheleleyo PDA ingqiqo Apple, leyo eyenza Apple Newton esemthethweni 1991, kodwa waba neziphene ezininzi kwaye ukusilela kwimarike.
Ngaphandle kwamathandabuzo, yayiyiPalm Inc. eyayiqhuba iiPDAs kwimarike kwiminyaka engama-90. Ezi zixhobo zaqala ukubandakanya imisebenzi enzima ngakumbi ukongeza, ubukhulu becala ngenxa yokubonakala kweenkqubo ezimbini zokusebenza zabo kubo, njengoko babenjalo. IWindows CE kunye neWindows Mobile. Ngombulelo kwezi nkqubo, ezi zixhobo ziye zakwazi ukuphucula imisebenzi yazo kwaye zisebenzise ngakumbi. Ukongezelela, utshintsho lwenziwe kuyilo lwayo, njengokufakwa kwesikrini sokuthintela esingasetyenziselwa kunye ne-stylus yokusetyenziswa ngokukhululekile, umzekelo.
Ukongeza, eminye imisebenzi yonxibelelwano ebaluleke kakhulu yaziswa. IBluetooth, iWiFi, izibuko le-infrared okanye iGPS baqala ukuba nobukho obukhulu kwiPDAs ezaqaliswa kwiimarike. Ngombulelo koku, ukusetyenziswa ngcono kunokwenziwa kubo. Unokude ulayishe isoftware ukuze uthathe ithuba layo emotweni. Ezinye iimodeli zaqala ukubandakanya iSIM khadi, ukuze kube nokwenzeka ukusebenzisa le PDA njengefowuni.
Le nkqubela phambili yanceda ekuqaliseni umsebenzi kwii-smartphones zokuqala. Kwakungo-2007 xa i-smartphone yokuqala yasungulwa. Ezi zixhobo zezo eziye zanceda ukuba unseat PDAs emarikeni, ekubeni ezi mobile phones yonke imisebenzi sele eyaziwa kwi PDA, kodwa ubukhulu compact ngaphezulu, ukongeza ukuba imisebenzi ngakumbi. I-Apple yeza kuqala nge-iPhone yayo kwaye kwakamsinya nje emva kokuba i-Android yenze ukungena kwayo kwintengiso. Ukuphela PDAs weza ngolu hlobo.
Yintoni iPDA ye
Kwicandelo lokuqala, apho siye sathetha malunga nokuba yintoni iPDA, sele siyikhankanye imisebenzi ethile. Kweli candelo siza kuthetha ngokubanzi malunga nokuba yintoni na iPDA. Igama lesixhobo lisinika ulwazi oluninzi malunga nalo, kuba ngumncedisi wedijithali lomntu, ngoko sinokufumana ingcamango malunga nemisebenzi ebonelela ngayo kunye nokusebenziseka kwesi sixhobo.
A PDA yenzelwe ukuba imisebenzi yemihla ngemihla inokucwangciswa ngendlela engcono, ngenxa yemisebenzi efakiweyo. Ukongeza ekusebenziseni kwayo ngokulula kunye nenyaniso yokuba sisixhobo esincinci esinokuthwala nathi ngamaxesha onke. Nasiphi na isigqeba sinokuthi i-ajenda yakhe iququzelelwe ngendlela elula ngenxa yokusetyenziswa kwale PDA. Unokubona ngokulula ukuba zeziphi iintlanganiso okanye idinga obunalo ngaloo veki, kunye nokufikelela ngokukhawuleza kulo naluphi na ulwazi loqhagamshelwano. Ulwazi olufana neentlanganiso, ukuqeshwa, amaxwebhu abalulekileyo, i-imeyile kunye neminye imisebenzi yolawulo yayifumaneka entendeni yesandla sakho enkosi kule PDA.
Ukongeza, njengoko beqhubela phambili kwimarike imisebenzi emininzi ifakwe kuyo. Uqhagamshelo lweBluetooth okanye iWiFi evunyelwe ukusebenzisa iPDA ngendlela engcono. Kuye kwenzeka ukuba i-imeyile ifumaneke ngokuthe ngqo kwisixhobo. Bekukho neemodeli ezineGPS, ukuze kwenziwe iindlela zokuhamba. Ukongeza, bekukho iimodeli ezinezibuko le-infrared, ngenxa yoku, unokusebenzisa isilawuli kude seTV. Ngoko amathuba okusebenzisa ezi zixhobo ayemaninzi, njengoko ubona.
Abantu abaninzi nabo basebenzisa PDA yabo ngokungathi laptop encinane. Omnye wemisebenzi ekhoyo kuyo yayikukwazi ukwenza utshintsho kumaxwebhu okubhaliweyo okanye i-spreadsheets kwi-fly. Ukongeza, ukuba babenonxibelelwano lwe-WiFi, abasebenzisi banokuthumela la maxwebhu nge-imeyile kwabanye abantu. Imisebenzi efana nekhaltyhuleyitha, ikhalenda enedatha epheleleyo yoqhagamshelwano lwabathengi, i-browser ye-Intanethi okanye umculo kunye nesidlali sevidiyo kuyo yanceda iPDA ukuba isetyenziswe ngamaxesha amaninzi. Nangona le misebenzi ayikwazanga ukuyigcina le PDA, eye yabona iiselfowuni zithatha indawo yayo ukusuka ekupheleni kweminyaka yoo-2000.
Ukunyamalala kwemarike
Njengoko sele sichazile kumaxesha amaninzi, mobile phones zithathe indawo PDAs kwimarike. Uyabona ukuba ii-smartphones zinemisebenzi emininzi eyenza ezi PDA zithandwa. Imisebenzi efana ne-ajenda, i-calculator, ukukwazi ukubona i-ajenda okanye ikhalenda yakho kunye nokuqeshwa kunye neentlanganiso, ukukwazi ukuhlela amaxwebhu kunye ne-spreadsheets okanye ukuba neBluetooth okanye i-WiFi kuyo. Zonke ezi ziimpawu esinazo kwii-smartphones zangoku.
Ukufika kwee-smartphones zokuqala ukusuka kwi-2007 waqala ukuqhuba ukwehla kweentengiso zePDA kwihlabathi jikelele, zombini ii-iPhones kunye neefowuni ze-Android zafumana ngokukhawuleza isabelo esikhulu semarike. Ezi zixhobo zilahlekelwe yindawo yazo ngokupheleleyo njengoko iifowuni eziphathwayo ezintsha, kunye neempawu ezininzi kunye namaxabiso akhuphisanayo, zaqaliswa kwimarike. Malunga neminyaka elishumi ngoku, sinokubona ukuba iiPDA ziye zanyamalala emarikeni ngenxa yokuqhubela phambili kweefowuni eziphathwayo okanye zibe nobukho obushiyekileyo kwezinye iimeko. Ngaphandle koku, kubekho iinzame ezininzi zokuphinda ziqalise ezi PDAs emarikeni kule minyaka idlulileyo, ezinye iibrendi zizama ukubenza isixhobo esithandwayo kwakhona.
Ezi nzame azibanga nasiphumo ebesinqwenelwa. ekubeni PDAs isixhobo esiphulukene nobukho bayo kwimarike yehlabathi. Enyanisweni, ukuba sijonga kwiivenkile ezifana Amazon, siya kuba nako ukubona ukuba ukuba sazisa igama PDA, sifumana ikakhulu phones Android, kodwa akukho nanye ngokwenene PDA njengoko ekuqaleni yasungulwa kwimarike, kule minyaka kukho ibe ziimodeli ezisebenzisa i-Android, kwiinzame zokuphucula ezi PDAs. Akubonakali ukuba okwangoku kukho nayiphi na injongo yokuzama ukuqalisa iimodeli ezintsha, kodwa ngubani owaziyo ukuba kwixesha elizayo naluphi na uphawu lukholelwa ukuba kusekho umdla kwaye benza umzamo omtsha wokunika ubomi obutsha kwiPDAs. Bekungayi kuba ngumnqa ukuba babuyela ekusebenziseni i-Android njengenkqubo yabo yokusebenza kwaye ke bafikelele kwinani elikhulu labasebenzisi kwihlabathi liphela.
