I-intanethi ngeke ibe khona ngaphandle kwamaseva
Iseva ikhompyutha eyenzelwe ukucubungula izicelo nokuletha idatha komunye ikhompyutha phezu kwe-intanethi noma inethiwekhi yendawo.
Igama elithi "iseva" liqondwa yiziningi ukuthi lisho isiphakeli sewebhu lapho amakhasi ewebhu angatholakala ngaphezu kwe-intanethi ngeklayenti njengesiphequluli sewebhu . Noma kunjalo, kunezinhlobo eziningana zamaseva ngisho nezindawo zendawo ezifana namaseva wefayela agcina idatha ngaphakathi kwenethiwekhi ye- intranethi .
Nakuba noma yikuphi ikhompyutha eqhuba isofthiwe ekhethekile ingasebenza njenge-server, ukusetshenziswa okujwayelekile kakhulu kwegama elibhekisela emishini enkulu kakhulu, enamandla kakhulu esebenza njengamaphampu aphonsela futhi adonse idatha kusuka ku-intanethi.
Amanethiwekhi amanethiwekhi amaningi asekela eyodwa noma ngaphezulu amaseva aphatha imisebenzi ekhethekile. Njengomthetho, ukwandisa inethiwekhi - ngokwemaklayenti axhuma kuyo noma inani lwedatha elihambayo - kungenzeka ukuthi amaseva amaningana adlala indima, ngayinye izinikezele ngenjongo ethize.
Eqinisweni, "iseva" yi- software ephethe umsebenzi othile. Noma kunjalo, i- hardware enamandla esekela le software iphindwe ibizwa ngokuthi iseva ngoba isofthiwe yesiphakeli eqondisa inethiwekhi yamakhulu noma izinkulungwane zamaklayenti idinga i-hardware ngamandla kakhulu kunalokho ongathengela ukusetshenziswa komthengi ojwayelekile.
Izinhlobo Ezijwayelekile Zaseva
Nakuba amanye amaseva azinikele lapho iseva isebenza khona kuphela umsebenzi, ezinye izinhlelo zokusebenza zingasebenzisa iseva eyodwa ngezinhloso eziningi.
Inethiwekhi enkulu, enenhloso jikelele esekela inkampani ephakathi nendawo izosusa izinhlobo eziningi zezinsiza:
Amaseva Wewebhu
Amaseva ewebhu abonisa amakhasi futhi asebenze izinhlelo zokusebenza ngokusebenzisa iziphequluli zewebhu.
Iseva isiphequluli sakho sixhunywe kuze kube manje yisiphakeli sewebhu esithumela leli khasi, noma yiziphi izithombe ongazibona, njll. Uhlelo lweklayenti, kulokhu, cishe isiphequluli njenge- Internet Explorer , i- Chrome , i-Firefox, i-Opera, i-Safari , njll.
Amaseva wewebhu asetshenziselwa zonke izinhlobo zezinto ngaphezu kokuletha umbhalo olula nemifanekiso, njengokulayisha nokusekela amafayela ku-inthanethi ngokusebenzisa isevisi yokugcina ifu noma amasevisi wokulondoloza inthanethi .
Amaseva we-imeyli
Amaseva e-imeyli enza lula ukuthumela nokuthola imiyalezo ye-imeyili.
Uma unamaklayenti e- imeyli kwikhompyutha yakho, isofthiwe ixhuma kwi-imeyli ye- IMAP noma i- POP ye- imeyli ukulanda imilayezo yakho kwikhompyutha yakho, ne- SMTP iseva ukuthumela imilayezo emuva nge-imeyli ye-imeyli.
Iseva ye-FTP
Ama-server we-FTP asekela ukudluliswa kwamafayela ngokusebenzisa amathuluzi we- File Transfer Protocol .
Ama-server we-FTP afinyeleleka kude nge- FTP iklayenti izinhlelo .
I-Identity Server
Amaseva e-Identity asekela ukungena nokulondeka kwabasebenzisi abagunyaziwe.
Amakhulu ezinhlobo ezahlukene zezinhlelo ezikhethekile ze-server asekela amanethiwekhi wekhompuyutha. Ngaphandle kwezinhlobo ezijwayelekile zezinkampani, abasebenzisi basekhaya bavame ukukhonjiswa nge amaseva wegeyimu e-intanethi, amaseva wengxoxo, izinsizakalo zokusakaza zomsindo, njll.
Izinhlobo Zeseva Yenethiwekhi
Amanethiwekhi amaningi ku-intanethi asebenzisa imodeli yokuxhumanisa ama- client-server ehlanganisa amawebhusayithi kanye nezinsizakalo zokuxhumana.
Imodeli ehlukile ebizwa ngokuthi inethiwekhi yontanga-to-peer ivumela wonke amadivayisi kunethiwekhi ukuba asebenze njengeseva noma iklayenti ngesisekelo esidingekayo. Amanethiwekhi wontanga anikeza ubukhulu obuningi bokungaboni ngoba ukuxhumana phakathi kwamakhompyutha kuhloswe kakhudlwana, kodwa ukusetshenziselwa okuningi kwezinethiwekhi zokuxhumana nabantu abangekho ngokwanele ukusekela ama-spikes amakhulu kakhulu.
AmaClusters eSeva
Iqoqo legama lisetshenziselwa kabanzi ekuxhumaneni kwenethiwekhi ukuze libheke ekusetshenzisweni kwemithombo ehlanganisiwe ye-computing. Ngokuvamile, iqoqo lihlanganisa izinsiza zamakhompyutha amabili noma ngaphezulu angasebenzisa ngokwahlukana ngenjongo ethile evamile (ngokuvamile amadivaysi noma imisebenzi yeseva).
Ipulazi lewebhu leseva liqoqo lamaseva wewebhu ahlanganisiwe, ngalinye linokufinyelela kokuqukethwe kusayithi elifanayo elisebenza njengeqoqo, ngokucabangela. Kodwa-ke, i-purists iphikisana nokuhlelwa kobuchwepheshe bepulazi leseva njengeqembu, kuye ngokuthi imininingwane ye-hardware ne-software yokucushwa.
Amaseva Ekhaya
Ngenxa yokuthi amaseva nje asofthiwe, abantu bangakwazi ukugijima amaseva ekhaya, kufinyeleleke kuphela kumadivayisi afakwe kunethiwekhi yabo yasekhaya. Isibonelo, ezinye izinkinobho ezinzima ezikwazi ukuxhumana nenethiwekhi zisebenzisa inqubo ye-server ye- Network Attached Storage yokuvumela ukuvumela ama-PC ahlukene kunethiwekhi yasemakhaya ukuba afinyelele isethi okwabelwana ngaso samafayela.
I-Plex media server iseva isisiza abasebenzisi ukuthi badle imidiya ye-digital kumadivayisi we-TV namadivaysi okuzijabulisa kungakhathaliseki ukuthi amafayela abezindaba asefu noma kwi-PC yendawo.
Ulwazi olungaphezulu kumaSeva
Njengoba isikhathi sokuphumula sibaluleke kakhulu kumaseva amaningi, ngokuvamile akukaze avaliwe kodwa esikhundleni sokugijima 24/7.
Noma kunjalo, amaseva ngezinye izikhathi awehla ngenhloso yokulungiswa okuhleliwe, yingakho amanye amawebhusayithi namasevisi azise abasebenzisi bawo "isikhathi sokuphumula" noma "ukugcinwa okuhleliwe." Amaseva angase futhi awe phansi engahlosile phakathi nento efana nokuhlaselwa kwe-DDoS .
