Client-Server Architecture

Client-iseva izakhiwo - kuba isakhiwo senhlangano ye kunethiwekhi yasendaweni noma lusatshalaliswe, lapho kukhona iseva ahlukene kanye nezinto zikagesi (amaklayenti), okuyinto phakathi umthwalo Computing inethiwekhi, siyivumele ukuba basebenze ndawonye. Isikhathi esining impela, nokuxhumana iseva ezisekelwe inethiwekhi nekhasimende nge inethiwekhi computer. Njengoba iseva kanye iklayenti kungaba amadivaysi hhayi kuphela ngogesi kanye software noma izicelo.

Inethiwekhi yendawo ne iseva ozinikele

amaklayenti-server izakhiwo kungase kusho isakhiwo lapho ikhasimende eziningana (ngokuvamile ezingaba yishumi)   amakhompyutha lapho ozinikele electronic unit central - iseva. iqembu okunjalo kwezinto zikagesi ibizwa ngokuthi "inethiwekhi yendawo ne iseva ozinikele."

Umlawuli inethiwekhi unelungelo kokuvinjwa ukushintsha ukucushwa leseva. It has ikhono ukufaka yiluphi uhlelo lokusebenza, kanye nokugcinwa engeyokuqala emaphakathi. Uhlelo oluyisisekelo oluthi Imininingwane egciniwe kungenziwa esisogwini ikhompyutha iseva, futhi (ngenxa yezizathu zokuphepha) kunoma iyiphi enye idivayisi elekthronikhi ukuthi kuyingxenye inethiwekhi. Indawo database iseva Web Kuyinto elula kakhulu futhi ngenxa ngale ndlela kuqinisekisa ngokuqhubeka bomsebenzi wonke amakhompyutha kunethiwekhi ngesikhathi umsebenzi lobuchwepheshe kuwebhu eyinhloko umshini.

Uxhumano nge iseva ozinikele livame ukuze kuqinisekiswe Seamless ukushintshanisa kwe-data phakathi kwamagatsha inhlangano enkulu noma inkampani. Enye ukusetshenziswa kwalesi izakhiwo unendawo inethiwekhi imidlalo yama-computer. Lokhu kuqinisekisa a okuqhubekayo ayimi ukufinyelela lokudlala ngenethiwekhi.

Client - uhlelo lwekhompyutha

Igama elithi "amaklayenti-server izakhiwo" eBhayibhelini, ngokuvamile lisho nokusatshalaliswa kwenethiwekhi phakathi iklayenti kanye iseva, lapho iklayenti uhlelo lwekhompyutha. Kulokhu, zonke idatha ebucayi Itholakala maphakathi Imininingwane base kukhompyutha iseva enamandla. Okubukwa ulwazi nokuvikelwa yaso nayo olunikezwa engeyokuqala iseva. Lokhu uhlaka lwenhlangano kunenzuzo kakhulu ngoba iseva kungaba kangcono kakhulu futhi eziqinile ukuvikela idatha ebucayi kusuka imizamo okungagunyaziwe ukufinyelela kubo. On iseva, setha zokulawula ukufinyelela, ngenxa okuyinto, ulwazi livulekele abasebenzisi kuphela, wanika amandla athile.

Izimiso ukwakha izakhiwo amaklayenti-server

Client-iseva izakhiwo lingakhiwa ngokuvumelana nesimiso:

1. kwakwakhe Dual, ukuhlinzeka i-web server kanye namakhasimende kweshumi.

2. kwakwakhe ternary kabani isakhiwo ine Lesisemkhatsini (I-Web site) itholakala phakathi iseva kanye iklayenti. Le yunithi uba umlamuleli e ukucutshungulwa izicelo kanye idatha noma ukuvikelwa lokuthola ulwazi, kanye nokuvikelwa yayo kusukela umonakalo nencithakalo. Kulokhu, isibalo sabasebenzi noma ukudlala amageyimu izindawo kunethiwekhi kungenziwa kakhulu lenyuka.

3. N-ного соединения, дающего возможность подключения к сети нескольких веб-серверов. Inombolo yabo incike ezingeni kwenethiwekhi umthwalo. Isibalo kumakhompyutha ungasebenza ekhonsathini kunethiwekhi Yiqiniso, okuningi ephakeme. amaseva Intermediate evamile unikezwa igama "leseva database", "Iseva isicelo".

Ngakho, kunethiwekhi yasendaweni nge kwakwakhe eyinkimbinkimbi isakhiwo amaseva N-multiple kanye amaklayenti amaningi kwenza ukusebenza kangcono futhi ergonomic ngaphezulu zonke izingxenye wesifunda inethiwekhi.
