1.Uyini umsizi wedijithali womuntu siqu?
Umsizi wedijithali womuntu siqu, ovame ukubizwa ngokuthi i-PDA, idivayisi noma uhlelo lokusebenza lwesofthiwe eklanyelwe ukusiza abantu ngemisebenzi ehlukahlukene kanye nemisebenzi. Ama-PDA ngokuvamile ahlome ngezici ezifana nokuphathwa kwekhalenda, inhlangano yokuxhumana, ukuthatha amanothi, kanye nokubonwa kwezwi.
Ama-PDA asiza abantu ukuthi bahlale behlelekile futhi bekhiqiza ngokuhlanganisa amathuluzi abalulekile abe yidivayisi eyodwa ehlangene. Angasetshenziselwa ukuphatha amashejuli, ukusetha izikhumbuzi, ukugcina ulwazi olubalulekile, ngisho nokwenza imisebenzi efana nokwenza izingcingo, ukuthumela imilayezo, nokufinyelela ku-inthanethi.
Ngokuthuthuka kwezobuchwepheshe, ama-PDA athuthukile ukuze afake abasizi ababonakalayo, abafana no-Siri, Alexa, noma Umsizi we-Google. Laba basizi ababonakalayo bancike ekuhlakanipheni kokwenziwa nasekucutshungulweni kolimi lwemvelo ukuze banikeze usizo lomuntu siqu, baphendule imibuzo, benze imisebenzi, futhi banikeze iziphakamiso ngokusekelwe kokuncanyelwayo komsebenzisi nemikhuba.
Kungakhathaliseki ukuthi kusesimweni sedivayisi ephathekayo noma uhlelo lokusebenza lwesofthiwe, izilekeleli zedijithali zomuntu siqu ziklanyelwe ukwenza lula kanye nokwenza lula imisebenzi yansuku zonke, ukukhulisa ukusebenza kahle, nokuthuthukisa ukukhiqiza kukonke.
2.PDA Izici:
Ukuphathwa Kolwazi Lomuntu Siqu (PIM): Ama-PDA ngokuvamile ahlanganisa izinhlelo zokusebenza zokuphatha ulwazi lomuntu siqu njengoxhumana nabo, amakhalenda, nohlu lwemisebenzi.
Ukuthatha amanothi: Ama-PDA angase abe nezinhlelo zokusebenza ezakhelwe ngaphakathi zokuthatha amanothi ezivumela abasebenzisi ukuthi babhale phansi imibono, benze uhlu lwezinto okufanele zenziwe, futhi badale izikhumbuzi.
I-Imeyili Nemilayezo: Ama-PDA amaningi anikela ngama-imeyili namandla okuthumela imiyalezo, okuvumela abasebenzisi ukuthi bathumele futhi bamukele imilayezo ekuhambeni.
Ukuphequlula Iwebhu: Amanye ama-PDA anokuxhumana kwe-inthanethi neziphequluli zewebhu, okuvumela abasebenzisi ukuthi bafinyelele amawebhusayithi, baseshe ulwazi, futhi bahlale bexhumekile ku-inthanethi.
Ukubuka Nokuhlela Amadokhumenti: Ama-PDA amaningi asekela ukubukwa kwamadokhumenti futhi aze avumele ukuhlelwa okuyisisekelo kwamadokhumenti afana namafayela e-Word ne-Excel.
Ukuxhumana Okungenantambo: Ama-PDA avame ukuba ne-Wi-Fi eyakhelwe ngaphakathi noma i-Bluetooth, evumela ukudluliswa kwedatha okungenantambo nokuxhumana namanye amadivaysi.
Ukudlalwa kwemidiya: Ama-PDA angafaka izidlali zomsindo nevidiyo, okuvumela abasebenzisi ukuthi balalele umculo, babuke amavidiyo, futhi babuke izithombe.
Ukuqoshwa Kwezwi: Amanye ama-PDA anamakhono okurekhoda ezwi akhelwe ngaphakathi, avumela abasebenzisi ukurekhoda amamemo ezwi noma izifundo.
Ukuzulazula kwe-GPS: Ama-PDA athile afika nokusebenza kwe-GPS, okuvumela abasebenzisi ukuthi bafinyelele amathuluzi okwenza imephu nawokuzulazula ukuze bathole izikhombisi-ndlela kanye nezinsiza zendawo.
Izinketho Zokunweba: Ama-PDA amaningi anezikhala zokunweba, njengezikhala ze-SD noma zekhadi le-microSD, ezivumela abasebenzisi ukuthi banwebe umthamo wesitoreji wedivayisi.
Kubalulekile ukuqaphela ukuthi ama-PDA aye ancipha eminyakeni yamuva nje, futhi izici zawo ziye zafakwa kakhulu kuma-smartphones namanye amadivaysi eselula. Ngenxa yalokho, ukusebenza nezici ezibalwe ngenhla zivame ukutholakala kuma-smartphone namathebhulethi esimanje.
3. Izinzuzo ze-PDA:
1.Ukuphatheka: Ama-PDA ane-Portable Lcd Screen mancane futhi alula, awenza aphatheke kakhulu futhi kulula ukuwaphatha.
I-2.Inhlangano: Ama-PDA ahlinzeka ngamathuluzi ahlukahlukene okuhlela amashejuli, abathintwayo, izinhlu zokwenziwa, namanothi, esiza abasebenzisi ukuthi bahlale behlelekile futhi baphathe imisebenzi yabo ngempumelelo.
3.Ukukhiqiza: Ama-PDA anikezela ngezici ezithuthukisa ukukhiqiza njengokuhlela amadokhumenti, ukufinyelela kwe-imeyili, nokuphequlula ku-inthanethi, okuvumela abasebenzisi ukuthi basebenze lapho besohambeni.
4.Ukuxhumana: Ama-PDA amaningi anamakhono okuxhumana akhelwe ngaphakathi, njenge-imeyili nemiyalezo, okwenza abasebenzisi bahlale bexhumekile futhi baxhumane ngokushesha nakalula.
5.Imisebenzi eminingi: Ama-PDA ngokuvamile ahlanganisa izici ezengeziwe njengezibali, izidlali zomsindo, amakhamera, namathuluzi okuzulazula, ahlinzeka abasebenzisi ngemisebenzi eminingi kudivayisi eyodwa.
4. Ububi be-PDA:
1.Usayizi Wesikrini Okhawulelwe: Ama-PDA ngokuvamile anezikrini ezincane, ezingenza kube inselele ukubuka nokusebenzisana nezinhlelo zokusebenza ezithile, amawebhusayithi, noma imibhalo.
2.Amandla Okucubungula Alinganiselwe: Uma kuqhathaniswa namanye amadivaysi afana namakhompyutha aphathekayo noma amathebulethi, ama-PDA angase abe namandla alinganiselwe okucubungula nomthamo wokugcina, ongakhawulela uhlobo nosayizi wemisebenzi angakwazi ukuyiphatha ngempumelelo.
3.Impilo Yebhethri Elinganiselwe: Ngenxa yobuncane bawo, ama-PDA avame ukuba nomthamo olinganiselwe webhethri, okusho ukuthi angadinga ukushajwa njalo, ikakhulukazi ngokusetshenziswa kanzima.
I-4.Obsolescence: Ama-PDA azinikezele asethandwa kakhulu ngenxa yokukhuphuka kwama-smartphone, ahlinzeka ngokusebenza okufanayo nezici ezithuthuke kakhulu. Lokhu kusho ukuthi ama-PDA nesofthiwe yawo ingase iphelelwe isikhathi futhi ingasekelwe ngokuhamba kwesikhathi.
5.Izindleko: Ngokuya ngezici namandla, ama-PDA angabiza kakhulu, ikakhulukazi uma eqhathaniswa nama-smartphone noma amathebulethi anikeza ukusebenza okufanayo noma okungcono ngentengo efanayo noma ephansi.
5.LCD, TFT kanye nobuchwepheshe besikrini sokuthinta ku-PDA
I-LCD (I-Liquid Crystal Display) ne-TFT (I-Thin-Film Transistor) zivame ukusetshenziswa ubuchwepheshe bokubonisa kuma-PDA (Abasizi Bedijithali Bomuntu).
1)I-LCD: Ama-PDA asebenzisa izikrini ze-LCD njengobuchwepheshe bawo bokubonisa obuyinhloko. Izikrini ze-LCD zihlanganisa iphaneli enamakristalu awuketshezi angalawulwa ngogesi ukuze abonise ulwazi. Izikrini ze-LCD zinikeza ukubonakala okuhle nombhalo obukhali nezithombe. Ngokuvamile zikhanyiswa emuva ukuze kuthuthukiswe ukubonakala ezimeni ezihlukahlukene zokukhanyisa. I-Lcd Glass Panel yonga amandla, iwenza afanelekele amadivayisi aphathekayo.
2)I-TFT: I-TFT iwuhlobo lobuchwepheshe be-LCD obusebenzisa ama-transistors efilimu elincanyana ukulawula amaphikseli angawodwana esibukweni. Ihlinzeka ngekhwalithi yesithombe engcono, ukulungiswa okuphezulu, nezikhathi zokuphendula ezisheshayo uma kuqhathaniswa nezibonisi ze-LCD ezivamile. Izibonisi ze-TFT zivame ukusetshenziswa kuma-PDA njengoba zinikeza imibala egqamile, isilinganiso esiphezulu sokungafani, nama-engeli okubuka abanzi.
3)Isikrini sokuthinta: Ama-PDA amaningi aphinde afake ukusebenza kwesikrini esithintwayo, okuvumela abasebenzisi ukuthi bahlanganyele ngokuqondile nesibonisi ngokuthepha, ngokuswayipha, noma ukusebenzisa ukuthinta. Ubuchwepheshe besikrini esithintwayo bungasetshenziswa kusetshenziswa izindlela ezihlukene, njengezikrini zokuthintwa eziphikisayo noma ezibambayo. Ngesikrini esithintwayo, ama-PDA anganikeza isixhumi esibonakalayo esinembile nesisebenziseka kalula, esivumela abasebenzisi ukuthi bazule kumamenyu, idatha yokufaka, futhi basebenzisane nezinhlelo zokusebenza kalula.
Kafushane, ubuchwepheshe be-LCD ne-TFT buhlinzeka ngamakhono okubonisa okubukwayo kuma-PDA, kuyilapho izikrini zokuthinta zithuthukisa ukusebenzisana komsebenzisi nokokufaka kulawa madivayisi.
