1.What is a personal digital assistant?
Mubatsiri wedhijitari, anowanzo kunzi PDA, chishandiso kana software application yakagadzirirwa kubatsira vanhu vane mabasa akasiyana siyana uye zviitiko. PDAs anowanzo kuve akashongedzerwa nemaitiro akadai sekarenda manejimendi, kuonana nesangano, kutora-noti, uye kunyange kucherechedzwa kwezwi.
MaPDA anobatsira vanhu kuti vagare vakarongeka uye vachigadzira nekuunza maturusi akakosha mumudziyo mumwe chete. Zvinogona kushandiswa kugadzirisa masheti, kuseta zviyeuchidzo, kuchengeta ruzivo rwakakosha, uye kunyange kuita mabasa akadai sekufona, kutumira mameseji, uye kuwana internet.
Nekufambira mberi mune tekinoroji, maPDA akashanduka kuti asanganise vabatsiri chaiwo, vakaita saSiri, Alexa, kana Google Assistant. Ava vabatsiri chaiwo vanovimba nehungwaru hwekugadzira uye kugadziridzwa kwemutauro wechisikigo kuti vape rubatsiro rwemunhu, kupindura mibvunzo, kuita mabasa, uye kupa mazano zvichienderana nezvido zvemushandisi nemaitiro.
Ingave iri muchimiro chechishandiso chemuviri kana chesoftware, vabatsiri vedhijitari vakagadzirirwa kurerutsa uye kugadzirisa mabasa ezuva nezuva, kuwedzera kushanda zvakanaka, uye kuwedzera chibereko chose.
2.PDA Zvimiro:
Personal Information Management (PIM): PDAs dzinowanzo sanganisira zvikumbiro zvekutarisira ruzivo rwemunhu sevanobatika, makarenda, uye rondedzero yebasa.
Kutora-cherechedzo: PDAs dzinogona kunge dzakavakira-mukati-yekutora-mapurogiramu anobvumira vashandisi kunyora pasi mazano, kuita zvinyorwa zvekuita, uye kugadzira zviyeuchidzo.
Email uye Messaging: Mazhinji maPDA anopa email uye mameseji kugona, achibvumira vashandisi kutumira uye kugamuchira mameseji pavanenge vachienda.
Kubhurawuza paWebhu: Mamwe maPDA ane chinongedzo cheinternet uye mabhurawuza, zvichiita kuti vashandisi vakwanise kuwana mawebhusaiti, kutsvaga ruzivo, uye kugara vakabatana online.

Kuridza midhiya: PDAs inogona kusanganisira maodhiyo uye vhidhiyo inoridza, ichibvumira vashandisi kuteerera mimhanzi, kuona mavhidhiyo, uye kuona mafoto.
Kurekodha Inzwi: Mamwe maPDA ane akavakirwa-mukati ekurekodha kwezwi, achigonesa vashandisi kurekodha memos yezwi kana hurukuro.
GPS Navigation: Mamwe maPDA anouya neGPS mashandiro, ayo anobvumira vashandisi kuwana mepu uye maturusi ekufambisa enzira uye masevhisi enzvimbo.
Sarudzo dzekuwedzera: MaPDA mazhinji ane nzvimbo dzekuwedzera, senge SD kana microSD kadhi slots, iyo inobvumira vashandisi kuwedzera simba rekuchengetedza mudziyo.
Izvo zvakakosha kuti uzive kuti PDAs dzave kushoma kuwanda mumakore achangopfuura, uye iwo maficha akanyanya kunyudzwa mumafoni uye mamwe nharembozha. Nekuda kweizvozvo, mashandiro uye maficha akanyorwa pamusoro anowanzo kuwanikwa muma smartphones emazuva ano uye mahwendefa.
3. Zvakanakira zvePDA:
1.Portability: PDAs nePortable Lcd Screen iduku uye isingaremi, zvichiita kuti zvive nyore kutakura uye zviri nyore kutakura kumativi ose.
2.Kuronga: PDAs inopa zvishandiso zvakasiyana-siyana zvekuronga mashedhi, vanobatana, mazita ekuita, uye manotsi, kubatsira vashandisi kuti varambe vakarongeka uye kutarisira mabasa avo zvakanaka.
3.Productivity: PDAs inopa zvibereko-zvinowedzera zvinhu zvakadai sekugadzirisa zvinyorwa, kuwana email, uye internet browsing, zvichibvumira vashandisi kushanda pakufamba.
4.Kukurukurirana: MaPDA akawanda ane maitiro ekukurukurirana, akadai se email uye kutumira mameseji, izvo zvinoita kuti vashandisi varambe vakabatana uye vataure nokukurumidza uye nyore.
5.Multifunctionality: PDAs inowanzobatanidza mamwe maitiro akaita se calculator, audio player, makamera, uye maturusi ekufambisa, kupa vashandi vane maitiro akawanda mumudziyo mumwe chete.
4. Zvakaipa zvePDA:
1.Limited Screen Size: PDAs kazhinji ine zvidzitiro zviduku, izvo zvinogona kuita kuti zvive zvakaoma kuona uye kushamwaridzana nemamwe mapurogiramu, mawebsite, kana zvinyorwa.
2.Limited Processing Power: Kuenzaniswa nemamwe madivayiri akaita semalaptops kana mahwendefa, PDAs inogona kunge iine simba shoma rekugadzirisa uye kuchengetedza simba, izvo zvinogona kudzora rudzi uye ukuru hwemabasa avanogona kubata zvakanaka.
3.Limited Battery Life: Pamusana pekukura kwavo kuduku, PDAs inowanzove ine simba shoma rebheteri, zvinoreva kuti dzingada kudzokorora nguva dzose, kunyanya nekushandiswa kwakanyanya.
4.Obsolescence: PDAs yakatsaurirwa yave isinganyanyi kufarirwa nekuda kwekukwira kwemafoni emafoni, ayo anopa maitiro akafanana uye mamwe maitiro epamusoro. Izvi zvinoreva kuti maPDA uye software yavo inogona kuve yechinyakare uye kusatsigirwa nekufamba kwenguva.
5.Mutengo: Zvichienderana nemaitiro uye maitiro, PDAs inogona kudhura zvakanyanya, kunyanya kana ichienzaniswa nemafoni efoni kana mahwendefa anopa zvakafanana kana zviri nani kushanda kwemutengo wakafanana kana wakaderera.
5.LCD, TFT uye Touchscreen teknolojia muPDA
LCD (Liquid Crystal Display) uye TFT (Thin-Film Transistor) inowanzoshandiswa kuratidza matekinoroji muPDAs (Personal Digital Assistants).
1)LCD: PDAs anoshandisa LCD skrini seyekutanga tekinoroji yekuratidzira. Zvidzitiro zveLCD zvine pani ine makristasi emvura anogona kudzorwa nemagetsi kuratidza ruzivo. LCD skrini inopa kutaridzika kwakanaka uye inopinza zvinyorwa uye magiraidhi. Iwo anowanzo kudzoserwa kumashure kuti awedzere kuoneka mumamiriro akasiyana emwenje. Lcd Glass Panel inoshanda nesimba, ichiita kuti ive yakakodzera kumidziyo inotakurika.
2)TFT: TFT imhando yeLCD tekinoroji inoshandisa yakaonda-firimu transistors kudzora mapikseli ega ega pachiratidziro. Iyo inopa zvirinani mhando yemufananidzo, yakakwirira resolution, uye nekukurumidza mhinduro nguva zvichienzaniswa neyechinyakare LCD kuratidza. Zviratidziro zveTFT zvinowanzo shandiswa muPDA sezvavanopa mavara akajeka, muyero wemusiyano wepamusoro, uye makona ekuona akafara.
3)Touchscreen: MaPDA mazhinji anosanganisirawo kubata-bata screen kushanda, zvichibvumira vashandisi kudyidzana zvakananga nechiratidziro nekudzvanya, kutsvaira, kana kushandisa majeti. Touchscreen tekinoroji inogona kuitwa uchishandisa nzira dzakasiyana, senge resistive kana capacitive touchscreens. Iine touchscreen, PDAs inogona kupa yakawedzera intuitive uye mushandisi-inoshamwaridzika interface, ichigonesa vashandisi kufamba nemamenyu, data rekuisa, uye kupindirana nemaapplication zvisina basa.
Muchidimbu, matekinoroji eLCD neTFT anopa maitiro ekuratidzira ePDAs, ukuwo ma touchscreens anowedzera kupindirana kwevashandisi uye kuisa pamidziyo iyi.
