Uthungelwano Ikhompyutha: iimpawu eziphambili, zokuhlela kunye nemigaqo zombutho

ubuntu Modern ngokoqobo awukwazi kuphila ngaphandle iikhompyutha, yaye enyanisweni ke ayemade ngangokuba eyadlulayo. Kule minyaka ingamashumi amabini idlulileyo, iikhompyutha zibe yinxalenye yazo zonke iindawo: kwi-ofisi kwiimfuno zemfundo, oko kudala imfuno ukuphuhlisa amathuba zobugcisa computer nokuphuhlisa software efanelekileyo.

Uthungelwano lweekhompyutha wenza akungebi kuphela ukwandisa imveliso kodwa ukunciphisa iindleko yesondlo sabo, kwakunye ukunciphisa ixesha yokosulela data. Ngamanye amazwi lo inethiwekhi esuka kwikhompyutha iye, iye iinjongo ezimbini: ukwabelana software ne-hardware, kwakunye nokufikelela evulekileyo kwizibonelelo data.

Ukwakhiwa lothungelwano computer zisekelwe kumgaqo "uhanjiselo-server '. Umxhamli - njengesakhi yokuyilwa ukuba usebenzisa i wegama eligqithisiweyo usebenzisa izakhono yomncedisi. Umncedisi, nayo, inika oovimba bayo kwezinye kwinethiwekhi nxaxheba. Kusenokwenzeka ilahlwe, liqulunqa iziko ledatha eqhelekileyo, ukusetyenziswa igalelo-output, njl

Networks ziza ngeendlela ezininzi:

- ndawo;

- zemimandla;

- Global.

Apha, kuba kulungile ukuchaza imigaqo kwi apho ezahlukeneyo zisekelwe iinethiwekhi computer.

Umbutho of network computer lendawo

Ngokuqhelekileyo, ezi iinethiwekhi ukudibanisa abantu kufutshane, ngoko ke kakhulu esetyenziswa ofisi kunye namashishini ugcino kunye processing, ngokudlulisela iziphumo yayo nabanye abathathi-nxaxheba.

Kukho into enje njenge "uthungelwano yethopholoji efanayo". Ngamafutshane, oko umzobo zejometri kwesixokelelwano kweekhompyutha. Kukho ezininzi izikim ezinjalo, ke, sicinga kuphela ezingundoqo: ibhasi, isangqa inkwenkwezi.

1. Bus - itshaneli lonxibelelwano ehlanganisa nodes kwi network. Ngalinye iindawo uyakwazi ukufumana ulwazi nangaliphi na ixesha lula, nokudlulisa - kuphela ukuba ibhasi ukhululekile.
2. Khalisa. units lidibane kuthotho kwisangqa, ngamanye isikhululo yokuqala inxulumene yesibini njalo njalo, kwaye emphakathini yokugqibela kunye wokuqala kweli ithopholoji ukusebenza, sivala ring. Eyona ethile iphambili yale lwezakhiwo kukuba xa ukusilela ubuncinane omnye element inethweki lonke elukhukweni enedumbe.
3. Star - apho compound imitha iindawo enxulumene kwiziko. Le modeli uqhagamshelo ukuya nabo maxesha akude, xa iikhompyutha yayimikhulu kakhulu, kwaye kuphela umatshini umzali ifumana kunye neenkqubo ulwazi.

Ngokumalunga networks zehlabathi, ngoko yonke into inzima kakhulu ngakumbi. Ukuza kuthi ga ngoku, apho kukho ngaphezu kwe-200 Eyona idumileyo - Internet.

Umehluko omkhulu zasekuhlaleni - yokungabikho kweziko njengabakundoqo olawulo.

inethiwekhi esuka kwikhompyutha enjalo ukwenza umsebenzi kwimigaqo emibini:

- iinkqubo umncedisi kufakwa kwi web sites ezithetha abasebenzisi nkonzo;

- iinkqubo umxhasi obekwe kwi kumsebenzisi PC kwaye i POP‧ umncedisi abasebenzisi beenkonzo.

uthungelwano Global kuvumela abasebenzisi ukuba ukufikelela kwiinkonzo ezahlukeneyo. Qhagamshela kwiinethiwekhi ezinjalo ngeendlela ezimbini: ngokusebenzisa uluntu ivuliwe mnxeba kunye ijelo elizinikeleyo.
