1.Kodi wothandizira digito ndi chiyani?
Wothandizira pa digito, yemwe nthawi zambiri amatchedwa PDA, ndi chipangizo kapena pulogalamu yamapulogalamu yopangidwira kuthandiza anthu ndi ntchito zosiyanasiyana. Ma PDA nthawi zambiri amakhala ndi zinthu monga kasamalidwe ka kalendala, gulu lolumikizana, kulemba zolemba, komanso kuzindikira mawu.
Ma PDA amathandiza anthu kukhala okonzeka komanso ochita bwino pophatikiza zida zofunika kukhala chipangizo chimodzi chophatikizika. Atha kugwiritsidwa ntchito kukonza ndandanda, kukhazikitsa zikumbutso, kusunga zidziwitso zofunika, komanso kuchita ntchito monga kuyimba foni, kutumiza mameseji, ndi intaneti.
Ndi kupita patsogolo kwaukadaulo, ma PDA asintha kuti aphatikizire othandizira, monga Siri, Alexa, kapena Google Assistant. Othandizira enieniwa amadalira luntha lochita kupanga komanso kukonza zilankhulo zachilengedwe kuti apereke chithandizo chamunthu, kuyankha mafunso, kuchita ntchito, ndikupereka malingaliro kutengera zomwe amakonda komanso zomwe amakonda.
Kaya ndi chida chakuthupi kapena pulogalamu yamapulogalamu, othandizira pakompyuta amapangidwa kuti azisavuta komanso kuwongolera ntchito zatsiku ndi tsiku, kuwonjezera mphamvu, komanso kukulitsa zokolola zonse.
2.PDA Zofunika:
Personal Information Management (PIM): Ma PDA nthawi zambiri amakhala ndi mapulogalamu owongolera zidziwitso zaumwini monga olumikizana nawo, makalendala, ndi mindandanda yantchito.
Kulemba: Ma PDA atha kukhala ndi mapulogalamu olembera omwe amalola ogwiritsa ntchito kulemba malingaliro, kupanga mndandanda wa zochita, ndikupanga zikumbutso.
Imelo ndi Mauthenga: Ma PDA ambiri amapereka ma imelo ndi mauthenga, kulola ogwiritsa ntchito kutumiza ndi kulandira mauthenga popita.
Kusakatula Paintaneti: Ma PDA ena ali ndi intaneti komanso asakatuli, zomwe zimathandiza ogwiritsa ntchito kupeza mawebusayiti, kufufuza zambiri, ndikukhalabe olumikizidwa pa intaneti.
Kuyang'ana ndi Kusintha Zikalata: Ma PDA ambiri amathandizira kuwonera zolemba komanso kulola kusinthidwa kofunikira ngati mafayilo a Mawu ndi Excel.
Lumikizani Opanda Ziwaya: Ma PDA nthawi zambiri amakhala ndi Wi-Fi kapena Bluetooth, kulola kusamutsa kwa data opanda zingwe ndikulumikizana ndi zida zina.
Kusewerera makanema: PDAs zitha kuphatikiza zosewerera zomvera ndi makanema, kulola ogwiritsa ntchito kumvera nyimbo, kuwona makanema, ndikuwona zithunzi.
Kujambulira Mawu: Ma PDA ena ali ndi luso lojambulira mawu, zomwe zimathandiza ogwiritsa ntchito kujambula ma memo kapena maphunziro.
GPS Navigation: Ma PDA ena amabwera ndi magwiridwe antchito a GPS, omwe amalola ogwiritsa ntchito kupeza mapu ndi zida zowunikira mayendedwe ndi ntchito zamalo.
Zosankha Zokulitsa: Ma PDA ambiri ali ndi mipata yowonjezera, monga SD kapena microSD khadi slots, zomwe zimalola ogwiritsa ntchito kukulitsa mphamvu yosungira chipangizochi.
Ndikofunikira kudziwa kuti ma PDA akhala akuchulukirachulukira m'zaka zaposachedwa, ndipo mawonekedwe awo adalowetsedwa kwambiri mumafoni am'manja ndi zida zina zam'manja. Zotsatira zake, magwiridwe antchito ndi mawonekedwe omwe atchulidwa pamwambapa amapezeka kwambiri m'mafoni amakono ndi mapiritsi.
3. Ubwino wa PDA:
1.Portability: PDAs okhala ndi Portable Lcd Screen ndi ang'onoang'ono komanso opepuka, kuwapangitsa kukhala osunthika kwambiri komanso osavuta kunyamula.
2.Organisation: PDAs amapereka zida zosiyanasiyana zokonzekera ndandanda, olankhulana nawo, mndandanda wa zochita, ndi zolemba, kuthandiza ogwiritsa ntchito kukhala okonzekera ndikuwongolera ntchito zawo moyenera.
3.Productivity: PDAs amapereka zinthu zowonjezera zokolola monga kusintha zolemba, kupeza maimelo, ndi kusakatula pa intaneti, zomwe zimalola ogwiritsa ntchito popita.
4.Kulankhulana: Ma PDA ambiri ali ndi luso loyankhulana, monga imelo ndi mauthenga, zomwe zimathandiza ogwiritsa ntchito kukhala ogwirizana komanso kulankhulana mofulumira komanso mosavuta.
5.Multifunctionality: PDAs nthawi zambiri imakhala ndi zina zowonjezera monga ma calculator, ma audio player, makamera, ndi zida zoyendetsera ntchito, kupatsa ogwiritsa ntchito ntchito zambiri mu chipangizo chimodzi.
4. Kuipa kwa PDA:
1.Limited Screen Size: PDAs nthawi zambiri amakhala ndi zowonetsera zazing'ono, zomwe zingapangitse kuti zikhale zovuta kuwona ndi kuyanjana ndi mapulogalamu ena, mawebusaiti, kapena zolemba.
2.Kuchepetsa Mphamvu Yopangira Mphamvu: Poyerekeza ndi zipangizo zina monga laputopu kapena mapiritsi, PDAs akhoza kukhala ndi mphamvu zochepa zogwirira ntchito ndi mphamvu zosungirako, zomwe zingalepheretse mtundu ndi kukula kwa ntchito zomwe angathe kuzigwira bwino.
3.Limited Battery Life: Chifukwa cha kukula kwawo kochepa, PDAs nthawi zambiri amakhala ndi mphamvu zochepa za batri, kutanthauza kuti angafunike kubwereza kawirikawiri, makamaka pogwiritsa ntchito kwambiri.
4.Obsolescence: PDAs odzipatulira akhala akudziwika kwambiri chifukwa cha kukwera kwa mafoni a m'manja, omwe amapereka ntchito zofanana ndi zinthu zapamwamba kwambiri. Izi zikutanthauza kuti ma PDA ndi mapulogalamu awo akhoza kukhala achikale komanso osathandizidwa pakapita nthawi.
5.Cost: Malingana ndi mawonekedwe ndi luso, PDAs akhoza kukhala okwera mtengo kwambiri, makamaka poyerekeza ndi mafoni a m'manja kapena mapiritsi omwe amapereka ntchito zofanana kapena zabwinoko pamtengo wofanana kapena wotsika.
5.LCD, TFT ndi Touchscreen luso mu PDA
LCD (Liquid Crystal Display) ndi TFT (Thin-Film Transistor) amagwiritsidwa ntchito kwambiri matekinoloje owonetsera mu PDAs (Personal Digital Assistants).
1)LCD: Ma PDA amagwiritsa ntchito zowonera za LCD ngati ukadaulo wawo wowonetsera. Zowonetsera za LCD zimakhala ndi gulu lokhala ndi makhiristo amadzimadzi omwe amatha kuwongoleredwa ndi magetsi kuti awonetse zambiri. Zowonetsera za LCD zimapereka mawonekedwe abwino komanso zolemba zakuthwa ndi zithunzi. Nthawi zambiri amawunikiridwa kuti azitha kuwoneka m'malo osiyanasiyana owunikira. Lcd Glass Panel ndiyopanda mphamvu, kupangitsa kuti ikhale yoyenera pazida zam'manja.
2)TFT: TFT ndi mtundu waukadaulo wa LCD womwe umagwiritsa ntchito ma transistors amafilimu owonda kwambiri kuti aziwongolera ma pixel omwe akuwonetsedwa. Imapereka chithunzithunzi chabwinoko, mawonekedwe apamwamba, komanso nthawi yoyankha mwachangu poyerekeza ndi zowonetsera zakale za LCD. Zowonetsera za TFT zimagwiritsidwa ntchito kwambiri mu PDAs chifukwa zimapereka mitundu yowoneka bwino, chiŵerengero chosiyana kwambiri, ndi ngodya zowonera zambiri.
3)Zenera logwira: Ma PDA ambiri amaphatikizanso magwiridwe antchito a touchscreen, kulola ogwiritsa ntchito kuti azitha kulumikizana mwachindunji ndi chiwonetserocho pogogoda, kusuntha, kapena kugwiritsa ntchito manja. Ukadaulo wapa touchscreen utha kukhazikitsidwa pogwiritsa ntchito njira zosiyanasiyana, monga zowonera kapena capacitive touchscreens. Ndi chotchinga chokhudza, ma PDA amatha kupereka mawonekedwe owoneka bwino komanso osavuta kugwiritsa ntchito, kupangitsa ogwiritsa ntchito kuyang'ana mindandanda yazakudya, zolowetsamo, ndikulumikizana ndi mapulogalamu mosavutikira.
Mwachidule, matekinoloje a LCD ndi TFT amapereka mphamvu zowonetsera ma PDA, pomwe zowonera zimakulitsa kulumikizana kwa ogwiritsa ntchito ndikuyika pazida izi.
