Iyini i-PDA? Kungenzeka kakhulu ukuthi kwesinye isikhathi uke wezwa noma ufunde okuthile ngaleli gama, mayelana nalawa ma-akhronimi. Kodwa ungase ungacacisi kahle iyini noma iyini i-PDA. Ngakho-ke, ngezansi sizokutshela konke odinga ukukwazi mayelana nale divayisi ukuze uphume ekungabazeni kwakho.
Sizokutshela ukuthi iyini i-PDA, ukuthi ingeyani, kanye nemvelaphi yayo, ukuze sazi kabanzi ngokuthi lolu cingo lwaqala kanjani. Kwabaningi benu kuwumqondo ojwayelekile, kungenzeka ukuthi wake waba nawo esikhathini esidlule. Noma ngabe yikuphi, uzokwazi ukwazi okwengeziwe ngale PDA.
Yini i-PDA
I-PDA iyisisetshenziswa sikagesi esincane, evame ukungena ephaketheni futhi ingabanjwa entendeni yesandla. Lolu cingo lusetshenziselwa ukuba nohlu loxhumana nabo siqu, ikhalenda elinama-aphoyintimenti, imihlangano noma izikhumbuzi, kanye nemisebenzi efana nesibali, isichasiselo namaspredishithi ahlala eseduze. Kuyidivayisi eye yanyamalala emakethe ngenxa yokukhuphuka kwama-smartphones, ngakho-ke, abaningi babona i-PDA njengesandulela sezingcingo eziphathwayo zamanje, njengoba lawa maselula athathe njengesisekelo imisebenzi ye-PDAs, futhi aphinde wethula inqwaba yamaselula. eminye imisebenzi eyengeziwe.
I-PDA iphendula isifinyezo ngesiNgisi, Kusho ukuthini Personal Digital Assistant, ngesi-Spanish esingahumusha ngokuthi Umsizi Wedijithali Womuntu Siqu. Iwumshini owaqalwa osukwini lwawo ikakhulukazi kubantu abasemkhakheni wezamabhizinisi (izikhulu noma abantu ababesebenza ezimakethe zamasheya), njengoba ngaleyo ndlela benomsizi wabo njalo eseduze, ephaketheni labo noma esikhwameni. Ngenxa yale divayisi bazokwazi ukubona ama-aphoyintimenti abo, isibonelo, noma bathole kalula imininingwane yokuxhumana yothile.
historia
Njengoba ungacabanga, iyidivayisi enendlela ethile emakethe. Yingakho abaningi sebeyazi kakade ukuthi i-PDA iyini, nakuba umlando wale divayisi uyinto engaziwa kwabaningi. Sishilo ukuthi le mishini ingabokuqala omakhalekhukhwini bamanje, ngakho-ke lokhu sekuvele kusinikeza umbono mayelana nesikhathi esesidlulile selokhu yethulwa emakethe.
I-PDA yaqala ukuthunyelwa kwayo emakethe ekupheleni kweminyaka yama-90. Imikhiqizo efana I-HP, i-Sharp noma i-Casio Babevele benezinye idayari ze-elekthronikhi emakethe engxenyeni yokuqala ye-90, lezi zinhlobo zibonakala njengezokuqala emndenini we-PDA. Nakuba kwaze kwaba ingxenye yesibili yaleyo minyaka eyishumi lapho amathuluzi okuqala alolu hlobo eqala ukuvela, amadivaysi aphelele kakhulu ngokwemisebenzi, njengePalm Inc (inkampani esanda kwakhiwa nayo). Nakuba owokuqala wasishiya umqondo ophelele we-PDA kwakungu-Apple, okwenza isikhulu se-Apple Newton ngo-1991, kodwa sasinamaphutha amaningi futhi kwaba ukwehluleka emakethe.
Ngaphandle kokungabaza, kwakuyi-Palm Inc. eyayishayela ama-PDA emakethe eminyakeni engu-90. Lezi zixhobo zaqala ukuhlanganisa imisebenzi eyinkimbinkimbi ngaphezu kwalokho, ikakhulukazi ngenxa yokubonakala kwezinhlelo ezimbili zokusebenza zazo kubo, njengoba zazinjalo. IWindows CE kanye neWindows Mobile. Ngenxa yalezi zinhlelo, lawa madivaysi akwazile ukuthuthukisa imisebenzi yawo futhi abe nokusetshenziswa okuningi. Ukwengeza, izinguquko zenziwe ekwakhiweni kwayo, njengokufakwa kwesikrini sokuthinta esingasetshenziswa ngokuhambisana ne-stylus ukuze sisetshenziswe ngokunethezeka, isibonelo.
Ngaphezu kwalokho, kwethulwa eminye imisebenzi yezokuxhumana ebaluleke kakhulu. I-Bluetooth, i-WiFi, imbobo ye-infrared noma i-GPS baqala ukuba khona okukhulu kuma-PDAs athulwe emakethe. Ngenxa yalokhu, zingasetshenziswa kangcono. Ungakwazi ngisho nokulayisha isofthiwe ukusizakala ngayo emotweni. Amanye amamodeli nawo aqala ukufaka i-SIM khadi, ukuze kube nokwenzeka ukusebenzisa le PDA njengocingo.
Le ntuthuko isize ukuthi kuqalwe umsebenzi kuma-smartphones okuqala. Kwakungo-2007 lapho kwethulwa i-smartphone yokuqala. Lezi zixhobo yizo ezisize ukukhulula ama-PDA emakethe, njengoba lawa maselula ayenayo yonke imisebenzi eyaziwa kakade ku-PDA, kodwa enobukhulu obuhlangene, ngaphezu kokuba nemisebenzi eminingi. I-Apple iza kuqala nge-iPhone yayo futhi ngemuva nje kokuthi i-Android ingene emakethe. Ukuphela kwama-PDA kwafika ngale ndlela.
Iyini i-PDA
Esigabeni sokuqala, lapho sikhulume ngokuthi iyini i-PDA, sesiyishilo kakade eminye imisebenzi. Kulesi sigaba sizokhuluma kabanzi mayelana nokuthi i-PDA ingeyani. Igama ledivayisi lisinikeza ulwazi oluningi mayelana nalo, njengoba liwumsizi womuntu siqu wedijithali, ukuze sithole umbono mayelana nemisebenzi ehlinzekayo kanye nokuba usizo kwalolu cingo.
I-PDA yakhelwe ngendlela yokuthi imisebenzi yansuku zonke ingahlelwa ngendlela engcono, ngenxa yemisebenzi eyifakile. Ngaphezu kokusebenziseka kwayo kalula kanye neqiniso lokuthi iyithuluzi elihlangene elingathwalwa nathi ngaso sonke isikhathi. Noma yimuphi umphathi angase ahlele i-ajenda yakhe ngendlela elula ngenxa yokusebenzisa le PDA. Ungabona kalula ukuthi yimiphi imihlangano noma ama-aphoyintimenti obunawo kulelo sonto, futhi ube nokufinyelela okusheshayo kunoma yiluphi ulwazi lokuxhumana. Ulwazi olufana nemihlangano, ama-aphoyintimenti, imibhalo ebaluleke kakhulu, i-imeyili neminye imisebenzi yokuphatha ibitholakala entendeni yesandla sakho ngenxa yale PDA.
Ngaphezu kwalokho, njengoba bethuthuka emakethe imisebenzi eyengeziwe yafakwa kuyo. Uxhumano lwe-Bluetooth noma i-WiFi evunyelwe ukusebenzisa i-PDA ngendlela engcono. Kwaba nokwenzeka ukuba i-imeyili itholakale ngokuqondile kudivayisi. Bekukhona namamodeli ane-GPS, ukuze kube nemizila yokuhamba. Ngaphezu kwalokho, bekunamamodeli anembobo ye-infrared, ngenxa yalokhu, ungasebenzisa isilawuli kude se-TV. Ngakho-ke amathuba okusebenzisa lezi zixhobo ayemaningi, njengoba ubona.
Abantu abaningi baphinde basebenzisa i-PDA yabo njengokungathi ilaptop encane. Omunye wemisebenzi etholakala kuyo bekuwukukwazi ukwenza izinguquko kumadokhumenti ombhalo noma amaspredishithi ngokushesha. Ngaphezu kwalokho, uma bebenoxhumano lwe-WiFi, abasebenzisi bebengathumela le mibhalo nge-imeyili kwabanye abantu. Imisebenzi efana nesibali, ikhalenda elinedatha ephelele yokuxhumana nekhasimende, isiphequluli se-inthanethi noma isidlali somculo nevidiyo kuso isize i-PDA ukuthi isetshenziswe izikhathi eziningi. Nakuba le misebenzi ingazange ikwazi ukulondoloza le PDA, ebone omakhalekhukhwini bethatha indawo yayo kusukela ekupheleni kweminyaka yawo-2000.
Ukunyamalala kwemakethe
Njengoba sesishilo ezikhathini ezimbalwa, omakhalekhukhwini bathathe indawo yama-PDA emakethe. Ungabona ukuthi ama-smartphone anemisebenzi eminingi eyenza lawa ma-PDA adumile. Imisebenzi efana ne-ajenda, umshini wokubala, ukwazi ukubona i-ajenda yakho noma ikhalenda ngama-aphoyintimenti nemihlangano, ukwazi ukuhlela amadokhumenti namaspredishithi noma ukuba ne-Bluetooth noma i-WiFi kuyo. Zonke lezi yizici esinazo kuma-smartphones amanje.
Ukufika kwama-smartphones okuqala kusuka ku-2007 waqala ukwehla ekuthengisweni kwama-PDA emhlabeni jikelele, womabili ama-iPhones namafoni e-Android athola ngokushesha isabelo esikhulu semakethe. Lawa madivaysi alahlekelwe indawo yawo ngokuphelele njengoba omakhalekhukhwini abasha, abanezici ezengeziwe namanani ancintisanayo, bethulwa emakethe. Cishe iminyaka eyishumi manje, siyabona ukuthi ama-PDA anyamalele emakethe ngenxa yokuthuthuka komakhalekhukhwini noma ukuba khona kwensalela kwezinye izimo. Ngaphandle kwalokhu, kube nemizamo eminingana yokwethula kabusha lawa ma-PDA emakethe phakathi neminyaka edlule, namanye amabhrendi azama ukuwenza abe idivayisi edumile futhi.
Le mizamo ayizange ibe nomphumela ofiselekayo, njengoba ama-PDA eyithuluzi elilahlekelwe ubukhona bayo emakethe yomhlaba. Eqinisweni, uma sibheka ezitolo ezifana ne-Amazon, sizokwazi ukubona ukuthi uma sethula igama elithi PDA, sithola kakhulu amafoni e-Android, kodwa awekho ngempela i-PDA njengoba yethulwa ekuqaleni emakethe, kule minyaka kukhona bekungamamodeli asebenzisa i-Android, emzamweni wokwenza lawa ma-PDA abe yisimanjemanje. Akubonakali ukuthi okwamanje kukhona inhloso yokuzama ukwethula amamodeli amasha, kodwa ngubani owaziyo ukuthi esikhathini esizayo noma yimuphi umkhiqizo ukholelwa ukuthi kusekhona isithakazelo futhi benza umzamo omusha wokunikeza impilo entsha kuma-PDA. Ngeke kuxake uma bebuyela ekusebenziseni i-Android njengohlelo lwabo lokusebenza futhi ngaleyo ndlela bafinyelele inani elikhulu labasebenzisi emhlabeni jikelele.
