Client Server vs Peer to Peer
Client server thiab peer to peer yog ob lub network architectures. Hauv cov neeg siv khoom server architecture, cov haujlwm lossis cov haujlwm ua haujlwm tau muab faib nruab nrab ntawm cov servers, thiab cov kev pabcuam raug thov los ntawm cov neeg siv khoom. Feem ntau, cov neeg siv khoom thiab cov servers sib txuas lus los ntawm lub computer network, tab sis lawv kuj tuaj yeem nyob ntawm tib lub cev. Hauv kev sib raug zoo rau cov phooj ywg architecture, cov dej num lossis kev ua haujlwm tau muab faib ua ke ntawm cov phooj ywg thiab cov phooj ywg no tau hais tias tsim kom muaj kev sib raug zoo rau phooj ywg. Cov phooj ywg muaj peev xwm thiab muaj cai tib yam. Cov phooj ywg ua ib feem ntawm lawv cov peev txheej xws li kev ua lub zog, disk cia lossis network bandwidth muaj rau lwm tus neeg koom hauv lub network.
Client Server yog dab tsi?
Raws li tau hais ua ntej, tus neeg siv khoom server architecture yog tsim los ntawm lub tswv yim ntawm servers muab kev pabcuam thiab cov neeg siv khoom thov cov kev pabcuam. Ib tus neeg rau zaub mov tiag tiag yog tus tswv tsev uas khiav ib lossis ntau qhov kev pabcuam server, uas qhia lawv cov peev txheej nrog cov neeg siv khoom. Tus neeg siv khoom pib qhov kev sib tham nrog cov servers los ntawm kev thov tus neeg rau zaub mov cov ntsiab lus lossis cov kev pabcuam. Servers ib txwm tos txais cov lus thov los ntawm cov neeg siv khoom. Muaj ntau ntau tus neeg siv khoom siv niaj hnub no. Tab sis lawv kuj muaj ntau yam nta xws li lub hauv paus kev ruaj ntseg database, uas tswj kev nkag mus rau cov kev sib koom ntawm cov neeg rau zaub mov. Cov neeg rau zaub mov muaj cov npe ntawm cov npe siv thiab cov passwords thiab tus neeg siv tsuas yog tso cai nkag mus rau lub network nkaus xwb yog tias lawv muab lub npe siv siv tau thiab tus password rau lub server. Tom qab lawv nkag mus, cov neeg siv tsuas tuaj yeem nkag mus rau cov peev txheej uas tau tso cai los ntawm tus thawj tswj hwm lub network. Kev siv dav dav xws li kev sib pauv email, kev nkag mus rau lub vev xaib thiab kev nkag mus rau cov ntaub ntawv tau tsim los ntawm cov neeg siv khoom-server architecture.
Peer to Peer yog dab tsi?
Nyob rau hauv ib tug phooj ywg rau cov phooj ywg network, cov kev pab cuam yog sib koom ntawm cov phooj ywg yam tsis muaj kev koom tes hauv nruab nrab los ntawm ib tug neeg rau zaub mov. Cov neeg sib tw ua haujlwm raws li cov neeg muab khoom thiab cov neeg siv khoom. Peer to peer systems siv qhov kev paub daws teeb meem sib tshooj ntawm cov ntawv thov txheej saum toj ntawm lub cev network topology. Lub tswv yim tom qab cov phooj ywg rau cov phooj ywg sib koom tes yog sib qhia cov peev txheej pheej yig li sai tau. Tsis muaj cov txheej txheem kev ruaj ntseg hauv nruab nrab thiab cov neeg siv kawg lawv tus kheej raug tso cai los tswj kev nkag mus rau cov peev txheej, txo cov kev ruaj ntseg hauv cov phooj ywg rau cov phooj ywg. Cov neeg siv tuaj yeem tsim cov ntsiab lus sib qhia uas lawv xav tau hauv lawv lub khoos phis tawj thiab kev ruaj ntseg tsuas yog muab los ntawm kev muab tus password thaum lawv tsim qhov sib qhia. Peer to peer network qauv tau siv los ntawm cov ntaub ntawv sib qhia nrov xws li Napster.
Qhov txawv ntawm Client-Server thiab Peer to Peer Network Architectures yog dab tsi?
Qhov sib txawv tseem ceeb ntawm cov neeg siv khoom-neeg rau zaub mov thiab cov phooj ywg rau cov neeg siv khoom yog tias nyob rau hauv cov neeg siv khoom-neeg rau zaub mov architecture, muaj cov neeg siv khoom uas thov rau cov kev pabcuam thiab cov servers uas muab kev pabcuam, tab sis nyob rau hauv cov phooj ywg rau cov phooj ywg, cov phooj ywg ua raws li ob tus neeg muab kev pabcuam thiab cov neeg siv khoom pabcuam. Tsis tas li ntawd, cov neeg siv-server systems xav tau cov ntaub ntawv nruab nrab ntawm cov neeg rau zaub mov thiab lawv kim heev rau kev siv dua li cov phooj ywg rau cov phooj ywg. Ntawm qhov tod tes, nyob rau hauv cov neeg siv-server system, cov neeg siv cov ntaub ntawv tshwj xeeb muab qib kev nkag mus rau cov neeg siv khoom, muab kev ruaj ntseg zoo dua li cov phooj ywg rau cov phooj ywg uas muaj kev ruaj ntseg los ntawm cov neeg siv kawg. Tsis tas li ntawd, cov phooj ywg rau cov phooj ywg sib koom ua ke raug kev txom nyem hauv kev ua haujlwm raws li tus naj npawb ntawm cov nodes nce, tab sis cov neeg siv-server systems muaj kev ruaj khov dua thiab tuaj yeem ntsuas ntau npaum li koj xav tau. Yog li ntawd, xaiv ib qho ntawm lwm qhov yog nyob ntawm ib puag ncig uas koj yuav tsum tau siv.
