Thuthukisa ukuqonda kwakho kwezinhlelo zokusebenza ezisekelwe kuwebhu
Isicelo sewebhu yinoma iyiphi uhlelo lwekhompiyutha eyenza umsebenzi othize ngokusebenzisa isiphequluli sewebhu njengeklayenti layo. Uhlelo lokusebenza lungaba lula njengebhodi lomlayezo noma ifomu lokuthintana kwiwebhusayithi noma njengeyinkimbinkimbi njengeprosesa yegama noma uhlelo lokusebenza lokudlala le-mobile multi-player olulanda efonini yakho.
Yini Umthengi?
I "iklayenti" isetshenziselwa imvelo yamakhasimende-iseva ukubhekisela ohlelweni umuntu asetshenziselwa ukuqhuba uhlelo lokusebenza. Isimo se-client-server yilapho amakhompiyutha amaningi ekwabelana ngolwazi njengokufaka ulwazi ku-database. I "iklayenti" uhlelo lokusebenza olusetshenziselwa ukungena kolwazi, futhi 'iseva' uhlelo lokusebenza elisetshenziselwa ukugcina ulwazi.
Yiziphi Izinzuzo Zokusebenzisa Izicelo Zewebhu?
Uhlelo lokusebenza lwewebhu lukhulula umthuthukisi wemfanelo yokwakha iklayenti ngohlobo oluthile lwekhompiyutha noma uhlelo oluthile lokusebenza, ngakho-ke noma ubani angasebenzisa uhlelo lokusebenza njengoba enokufinyelela kwe-intanethi. Njengoba ikhasimende ligijima kusiphequluli sewebhu, umsebenzisi angasebenzisa i-IBM-ehambisanayo noma i-Mac. Bangakwazi ukuqhuba i-Windows XP noma i-Windows Vista. Bangase basebenzise i-Internet Explorer noma i-Firefox, nakuba ezinye izinhlelo zidinga isiphequluli esithile sewebhu .
Izinhlelo zeWeb zivame ukusebenzisa inhlanganisela ye-server-side script (ASP, PHP, njll) kanye neskripthi seseklayenti (HTML, Javascript, njll) ukuthuthukisa uhlelo lokusebenza. Iskripthi se-client-side sibhekene nokwethulwa kolwazi ngenkathi iskripthi seseva-side isebenza nazo zonke izinto ezinzima njengokugcina nokuthola ulwazi.
Ukuthi Izikhathi Zewebhu Zinezikhathi Zini Ziningi?
Izinhlelo zokusebenza zeWeb zilokhu zizungezile kusukela ngaphambi kokuba iWeb Wide Web izuze ukuthandwa okuvamile. Isibonelo, i-Larry Wall ithuthukise i-Perl, ulimi oluthandwayo lwe-server-side scripting, ngo-1987. Lokho kwakuyiminyaka eyisikhombisa ngaphambi kokuba i-intanethi iqale ukuzuza ukuthandwa ngaphandle kwemibuthano yezemfundo nobuchwepheshe.
Izinhlelo zokusebenza zokuqala zewebhu ezincane zazilula, kodwa ngasekupheleni kweminyaka engu-90 babona ukuqhuma ekusetshenzisweni kwezicelo zewebhu eziyinkimbinkimbi. Namuhla, izigidi zabantu baseMelika zisebenzisa uhlelo lokusebenza lwewebhu ukuze bafake intela yabo engenayo inthanethi, benze imisebenzi yasebhange e-inthanethi, bahlale bexhumana nabangani nabathandekayo nokunye okuningi.
Izicelo zeWebhu zenzeke kanjani?
Izinhlelo eziningi zewebhu zisekelwe kumklami we-client-server lapho iklayenti ingena khona ulwazi ngenkathi iseva igcina futhi ithola ulwazi. Imeyili ye-intanethi yisibonelo salokhu, nezinkampani ezifana ne-Gmail ye-Google ne-Outlook yakwaMicrosoft ehlinzeka ngamakhasimende we-imeyili asekelwe kuwebhu.
Phakathi neminyaka embalwa eyedlule, kube khona ukucindezela okukhulu kwezinhlelo zokusebenza zewebhu ezenzelwe imisebenzi engajwayelekile ukuthi iseva igcine ulwazi. I-processor yakho yegama, isibonelo, igcina amadokhumenti kwikhompyutha yakho, futhi ayidingi iseva.
Izinhlelo zokusebenza zewebhu zinganikeza ukusebenza okufanayo futhi zithole inzuzo yokusebenza kumapulatifomu amaningi. Isibonelo, uhlelo lokusebenza lwewebhu lungenza njengeprosesa yegama, ukugcina imininingwane efwini nokukuvumela ukuthi 'ulande' idokhumenti ku-hard drive yakho.
Uma ngabe ususebenzise iwebhu isikhathi eside ukuze ubone ukuthi izinhlelo zokusebenza zewebhu ezithandwayo ezinjengezakhamera ze-Gmail noma ze-Yahoo zishintshile kanjani eminyakeni edlule, ubonile ukuthi izinhlelo zokusebenza zewebhu eziyinkimbinkimbi ziye zaba kanjani. Iningi laleyo nkimbinkimbi yenzelwa i-AJAX, eyimodeli yokuhlela yokudala izinhlelo zokusebenza zewebhu ezithandayo.
I-G Suite (ngaphambili yezinhlelo zokusebenza ze-Google ), iMicrosoft Office 365 yizinye izibonelo zesitshalo esisha esisha sezinhlelo zokusebenza zewebhu. Izinhlelo zokusebenza ezixhuma kwi-intanethi (njenge-app yakho ye-Facebook, uhlelo lwakho lokusebenza lweDropbox noma uhlelo lwakho lokubhanka ku-intanethi) nazo izibonelo zendlela izinhlelo zokusebenza zewebhu ezenzelwe ngayo ukusetshenziswa okuqhubekayo okuthandwa kwewebhu.
