Ukuphucula ukuqonda kwakho kwiinkqubo zesicelo-based web
Isicelo sewebhu kukho nayiphi na inkqubo yekhompyutheni eyenza umsebenzi othile ngokusebenzisa isiphequluli sewebhu njengomxhasi wayo. Isicelo singaba njengento elula njengebhodi yomyalezo okanye ifom yoqhagamshelwano kwiwebhusayithi okanye njengeyinkimbinkimbi njengeprogram okanye igama le-app-player player gaming app oyikhuphela kwifowuni yakho.
Yintoni Umthengi?
"Umthengi" usetyenziselwa kwindawo yokugcina umxhasi ukuba aphendule kwinkqubo umntu asebenzisayo ukuqhuba isicelo. Imo-client-server kwindawo enye apho ikhompyutha ezininzi zelana ngolwazi olunjengokufaka ulwazi kwiziko ledatha. "Umsebenzisi" isisicelo esisetyenziselwa ukungena ulwazi, kwaye 'umncedisi' isisicelo esisetyenziselwa ukugcina ulwazi.
Ziziphi iinzuzo zokusebenzisa izicelo zewebhu?
Isicelo sewebhu siyanceda umthuthukisi woxanduva lokukwakha umthengi ngolunye uhlobo lwekhompyutha okanye inkqubo ethile yokusebenza, ngoko ke nabani na ongasebenzisa isicelo kunye nabanokufikelela kwi-intanethi. Ekubeni umthengi ugijimela kwisiphequluli sewebhu, umsebenzisi unokusebenzisa i-IBM-compatible okanye iMac. Bangakwazi ukuqhuba iWindows XP okanye iWindows Vista. Baya kusebenzisa i-Internet Explorer okanye i-Firefox, nangona ezinye izicelo zifuna i- Web browser .
Izicelo zewebhu zixhaphaza ngokubanzi inxalenye yecandelo le-server (ASP, PHP, njl.) Kunye neskripthi secala labathengi (HTML, Javascript, njl.) Ukuphuhlisa isicelo. I-script-side script ibandakanya ukunikezelwa kolwazi ngelixa umgca we-side-script usebenzisana nazo zonke izinto ezinzima njengokugcina nokufumana ulwazi.
Zikude Kangakanani Izicelo Zewebhu?
Izicelo zewebhu ziye zajikeleza ukususela ngaphambi kokuba iNdebe yeWebhu yehlabathi izuzwe ngokubanzi. Ngokomzekelo, uLarry Wall uvelise i-Perl, ulwimi olusandulweyo lwe-server-side, ngo-1987. Kwakuyiminyaka esixhenxe ngaphambi kokuba intanethi iqale ukufumana ukuthandwa ngaphandle kwezemfundo kunye neeteknoloji.
Izicelo zokuqala zewebhu eziqhelekileyo zilula, kodwa ekupheleni kwe-90 zabona i-push push to applications. Namhlanje, izigidi zabantu baseMerika zisebenzisa i-web application ukufaka ifayile yabo yentlawulo kwi-intanethi, ukwenza imisebenzi yasebhanki ye-Intanethi, uhlale uxhulumana nabahlobo kunye nabathandekayo kunye nokunye okuninzi.
Izicelo zeWebhu zenzeke njani?
Izicelo ezininzi zewebhu zisekwekwakhelo lwe-client-server apho umthengi angena ngolwazi ngelixa umncedisi ugcina kwaye ufumana ulwazi. Imeyili ye-intanethi ngumzekelo wale nto, kunye neenkampani ezifana ne-Google ye-Gmail kunye neMicrosoft Outlook enikezela abathengi be-imeyile e-web.
Kule minyaka emininzi edlulileyo, kukho i-push enkulu kwi-applications yewebhu ekuphuhliswa kwimisebenzi engaqhelekanga ukuba iseva igcine ulwazi. Umprofeti wakho wegama, umzekelo, ugcina amaxwebhu kwikhompyuter yakho, kwaye akadingi umncedisi.
Izicelo zewebhu ziza kunika ukusebenza okufanayo kwaye zifumane inzuzo yokusebenza kwiiplatifti ezininzi. Umzekelo, isicelo sewebhu singenza njengeprosesor yegama, ukugcina ulwazi kwifu kwaye kukuvumela ukuba 'ukukhuphela' loxwebhu kwi-hard drive yakho.
Ukuba sele usebenzisa i-web ubude ngokwaneleyo ukubonela indlela izicelo ezidumile zewebhu ezifana nabaxumi bee-Gmail okanye ze-mail zatshintshile ngaphezu kweminyaka, ubonile indlela izicelo zewebhu eziyinkimbinkimbi. Uninzi lwaloo nkqubela kukuba ngenxa ye-AJAX, eyimodeli yokulungiselela ukudala izicelo ezininzi zewebhu eziphendulayo.
I-G Suite (yangaphambili i- Google Apps ), iMicrosoft Office 365 yimizekelo yezizukulwana ezitsha ngokutsha kwezicelo zewebhu. Izicelo zefowuni ezidibanisa kwi-intanethi (njenge-app yakho ye-Facebook, app yakho yeDropbox okanye i- app yakho yasebhanki ye-intanethi) yimizekelo yeendlela izicelo zewebhu eziye zenzelwe ukusetyenziswa okugqithiseleyo kwewebhu.
