webOS vs iOS vs Android
Kev siv cov khoom siv txawb tau nrawm nrawm. Qhov no tau ua rau kev sib tw ntawm cov tuam txhab sib tw uas tsim cov kev ua haujlwm mobile ua rau muaj kev sib ntaus sib tua kom tau txais kev tshaj lij. webOS tsim los ntawm HP (Hewlett-Packard), iOS tsim los ntawm Apple, thiab Android tsim los ntawm Google tau dhau los ua cov neeg tseem ceeb hauv kev ua lag luam mobile. Txawm hais tias, cov txheej txheem kev khiav hauj lwm no yuav zoo dua ib leeg hauv ntau qhov sib txawv lossis thaj chaw, tag nrho peb lub tshuab ua haujlwm tau raug saib xyuas los ntawm cov neeg siv khoom siv mobile.
webOS
webOS yog Linux raws li mobile operating system. Nws yog qhov kev ua haujlwm zoo tsim los ntawm HP. Qhov tseeb, Palm tau qhia txog webOS thaum Lub Ib Hlis 2009 (rau Palm Pre cov khoom siv, tso tawm ntawm Sprint), uas ua ntej Palm OS. webOS tam sim ntawd tau txais txiaj ntsig zoo vim nws siv tau, Web 2.0 kev koom ua ke, qhib architecture thiab ntau yam haujlwm. Tab sis HP yuav Xibtes xyoo 2010, thiab webOS tau hais tias yog lub hauv paus tseem ceeb ntawm kev txhawb siab rau kev yuav Palm. webOS 2.2 thiab webOS 3.0 tau tshaj tawm thaum Lub Ob Hlis 2011, nrog HP Veer/HP Pre 3 smatphones thiab HP TouchPad ntsiav tshuaj computers, feem. HP tab tom npaj yuav nthuav tawm cov version ntawm webOS thaum kawg ntawm 2011 uas yuav khiav hauv qhov rais, kom nws tuaj yeem ntsia tau rau txhua lub tshuab HP.
iOS
iOS (yav dhau los hu ua iPhone OS) yog lub xov tooj ntawm tes ua haujlwm tsim los ntawm Apple. iOS no yog ib tug ncaj derivation ntawm Kua lub Mac OS X, thiab nws yog ib tug UNIX-zoo li operating system. Keeb kwm, iOS tuaj nrog iPhones, tab sis tom qab ntawd nws tau nruab rau iPod kov, iPad thiab Apple TV li.iOS tuaj yeem nruab rau ntawm 3rd tog kho vajtse yam tsis tau txais daim ntawv tso cai los ntawm Apple. Tam sim no cov neeg siv tuaj yeem rub tawm ntau dua li ib nrab lab daim ntawv thov rau iOS los ntawm Apple App khw. Tsis tas li ntawd, iOS yog lub luag haujlwm rau ntau tshaj ib nrab ntawm kev siv lub vev xaib mobile (tshwj tsis yog iPad) hauv North America. iOS interface yog ua raws li cov lus taw qhia ntau yam nrog rau cov sliders, keyboards thiab cov nyees khawm, uas muab cov lus teb tam sim rau cov neeg siv cov tswv yim. Cov neeg siv tuaj yeem siv kev sib cuam tshuam xws li swipes, kais thiab pinches sib txuas lus nrog iOS. Qee daim ntawv thov yog "co-sensitive", txhais tau hais tias qee yam haujlwm xws li undo thiab rotating tuaj yeem ua tau los ntawm tsuas yog co lub cuab yeej. iOS no muaj plaub txheej ntawm abstraction hu ua Core OS, Core Services, Media thiab Cocoa Touch. iOS xav tau ib ncig ntawm 600MB ntawm kev cia ua haujlwm.
Android
Android yog pawg software txawb tsim los ntawm kev ua haujlwm, nruab nrab thiab cov ntawv thov. Lub tuam txhab Android yog nws thawj tus tsim tawm, thaum Google yuav nws hauv 2005. Android operating system yog raws li Linux. Cov tswv cuab ntawm OHA (Open Handset Alliance), uas suav nrog lub tuam txhab Google, tso tawm Android, thaum AOSP (Android Open Source Project) yog lub luag haujlwm rau nws cov kev saib xyuas ntxiv. Android tau kwv yees tias yog lub platform nrov tshaj plaws rau cov xov tooj smartphones hauv xyoo 2010. Muaj ntau tshaj li ib feem peb ntawm ib lab daim ntawv thov ("Apps") muaj rau Android, thiab tus lej no nce zuj zus ua tsaug rau cov zej zog loj ntawm cov neeg tsim khoom mob siab rau tsim cov apps. Cov ntawv thov tuaj yeem rub tawm los ntawm Android Market (lub khw app online khiav los ntawm Google) lossis los ntawm cov chaw thib 3.
Kev txhim kho ntawm Android feem ntau yog Java raws. Ib feem loj ntawm Java 5.0 cov tsev qiv ntawv tau txais kev txhawb nqa hauv Android. Ntau lub tsev qiv ntawv Java uas tsis tau txais kev txhawb nqa yog muaj kev hloov pauv zoo dua (lwm cov tsev qiv ntawv zoo sib xws) lossis tsuas yog tsis xav tau (xws li cov tsev qiv ntawv luam ntawv, thiab lwm yam). Cov tsev qiv ntawv zoo li java.awt thiab java.swing tsis txaus siab vim tias Android muaj lwm lub tsev qiv ntawv rau cov neeg siv interfaces. Android SDK txhawb nqa lwm lub tsev qiv ntawv thib peb xws li org.blues (Bluetooth txhawb nqa). OHA yog tsim los ntawm ntau lub tuam txhab tshwj xeeb rau kev txhim kho cov qauv qhib rau cov khoom siv txawb. Android code tau tso tawm dawb thiab qhib qhov chaw raws li Apache daim ntawv tso cai. Thaum kawg, Android code tau muab tso ua ke rau hauv Davilk opcodes. Davilk yog lub tshuab virtual tshwj xeeb ua kom zoo rau cov khoom siv txawb nrog cov peev txheej tsawg xws li lub zog, CPU thiab nco.
Qhov txawv ntawm webOS thiab iOS thiab Android yog dab tsi?
Txawm tias tag nrho peb lub platforms / kev ua haujlwm sib piv rau ib leeg, lawv muaj lawv qhov siab thiab qis. iOS no tau hais tias muaj qhov zoo tshaj plaws, cov kua dej ntau tshaj, ua kom huv thiab feem ntau cov neeg siv nkag siab zoo uas tuaj yeem siv tau yooj yim los ntawm thawj-timer. webOS suav hais tias tsis deb tom qab ntawm kev siv tau, tab sis yuav xav tau qee qhov kev siv rau tus tshiab. Tab sis, Android yog kom meej meej nyob rau hauv peb txoj hauj lwm thaum nws los txog rau tus neeg siv interface. Qhov kev sib txawv no yog tsim los ntawm kev sib piv nkaus xwb thiab nws tseem ceeb heev uas yuav tsum nco ntsoov tias tag nrho peb cov neeg siv interfaces zoo heev. Ib qho laj thawj rau Android kev lag luam hauv cheeb tsam no yog tias Android 2.x tsis haum rau cov ntsiav tshuaj (Google lees paub qhov no), tab sis tseem tau siv nrog lawv, txawm tias Android 3.x yog cov ntsiav tshuaj tshwj xeeb OS.
Android suav tias yog tus yeej meej hauv kev sib ntaus sib tua. Cov neeg siv tuaj yeem hloov kho yuav luag txhua yam ntawm Android, thaum lwm ob tsis muaj ntau txoj hauv kev kho kom haum. iOS tso cai rau customization ntawm tsuas yog lub app layout, whereas webOS yog ib tug uas tsawg kawg nkaus tus nqi ntawm customizations. Ib qho ntawm cov yam ntxwv zoo tshaj plaws ntawm Android yog nws cov kev txhawb nqa rau Widgets, uas tso cai rau saib txhua yam koj xav paub ntawm ib sab, tsis yog yuav tsum qhib thiab kaw cov apps (xws li hauv iOS).
Hais txog email, cov neeg siv nyiam nyiam qhov yooj yim uas iOS nqa tau, tab sis webOS daim npav sib cuam tshuam (uas tso cai rau tig rov qab los ntawm nplooj ntawv web thiab email tshiab) suav tias tsim nyog rau email. Txawm li cas los xij, kev theej-thiab-paste feature hauv iOS no yog qhov zoo tshaj plaws ntawm peb, uas txhais tau hais tias flipping rov qab thiab tawm yog tsis tshua xav tau lawm.
HP TouchPad thiab HP Palm Pre 3 (uas khiav webOS 3.0) muaj kev ua haujlwm zoo heev thiab tsis sib haum xeeb, txawm hais tias Android tsis nyob deb ntawm kev hloov ntawm cov apps nrawm heev. Txawm li cas los xij, iOS yog nyob deb ntawm kev ua haujlwm ntau lub peev xwm. Txawm li cas los xij, iOS yog tus yeej thaum nws los txog rau lub khw muag khoom app. iOS app khw muaj ib qho kev sau loj heev (ntau dua 500 txhiab) ntawm cov apps. Txawm li cas los xij, nws yog kev lag luam kaw. Android muaj ib nrab ntawm cov apps, tab sis qee zaum qhov zoo tuaj yeem nug. Lub caij no webOS app khw tsuas muaj ob peb txhiab tus apps muaj rau rub tawm.
