E o tsejoa hore e 'ngoe ea seo a se finyeletseng bohlokoa ka ho fetisisa tse lekholo tse fetileng e ne e le popo ea moloko oa batho le ho ntshetsa pele ka potlako theknoloji e lesedi - theknoloji e eo, ho sebelisa lik'homphieutha le mefuta e sa tšoaneng ea dinetweke tseo k'homphieutha, store, thulaganyong, sokolla le fetisetsa e ngata ea litaba. Ke habohlokoa ho hlokomela hore e joalo e qhoma ka potlako ba moloko oa batho lesedi fetohile khoneha feela ka mor'a dinetweke tseo k'homphieutha le puisano e 'nile ba bōptjoa.

Mefuta eohle ea dinetweke tseo ya khomphuta ya hao ke pokello ea lik'homphieutha aba fetang sebakeng itseng le ya kokangana ke metjha e khethehileng, e le hore u fetisetsa ya data. Kajeno dinetweke tseo ya khomphuta ya hao ba ho pharaletseng a sebelisa, mefuta e sa tšoaneng ea dinetweke tseo ya khomphuta ya hao e sebetsang lefatšeng ka bophara le ho sebelisana le balekane ba bona. kutlwisiso morao-rao tsa lintho tse hlahang dinetweke se entse hore ho e tlhophiso ea molao-motheo ea sebaka. Ho latela tlhophiso sena se akarelletsa mefuta e joalo ea dinetweke tseo ya khomphuta ya hao:

Global Area Network (Halh) - khokahano ea lefatše lohle ea lik'homphieutha le marangrang a teng likarolong tse sa tšoaneng tsa lefatše.

Wide Area Network (Wan) - tse nthja khōlō hore kopana e nthja ya khomphuta ya hao ka boemo ba lik'honthinenteng le linaheng;

Metropolitan Area Network (MAN) - dinetweke tseo hōle tsa lik'homphieutha le khokahano ka hara libaka le diyuniti tse ling tsa tsamaiso;

Local Area Network (Lan) - Lan, ho fana ka maikutlo le nyalano ea lik'homphieutha teng le hōle batlang e le khutšoanyane - ho etsa mohlala, ka hara moaho tšoanang.

Wan le MAN li dineteweke lebatowa. Ke habohlokoa ho hlokomela hore ho fihlela joale, ho e-ba le karohano ea dinetweke tseo ya khomphuta ya hao ka Wan le MAN e haholo tlas'a maemo a, ka hona joale hoo e ka bang mong le e mong marangrang lebatowa kenyelelitsoe marangrang efe kapa efe ea lefatše.

mekhatlo e mengata e na le thahasello ka ho fana ka boemo bo phahameng ba tshireletso ya lesedi khahlanong encroachments ho tswa kantle (ka mohlala, masole a, libanka, joalo-joalo), bopa dinetweke tseo tsa bona, e tsejoang e le kopanetsweng a. Ka marangrang khompani 'na a akarelletsa tse likete tse mashome lik'homphieutha tse teng le hōle haholo le e mong le tse ling tse, ho etsa mohlala, linaheng tse sa tšoaneng.

Ka ho fetisisa a atile lefatšeng numerically ke dinetweke tseo ea moo k'homphieutha.

The tšobotsi ea bohlokoa ke ka monyetla oa ho tse nthja sebakeng ea moo ho hokahanya lik'homphieutha kabel sa retelehele metjha e bakeng sa phetiso ya data, sebelisa tse nthja lohle sebakeng (mohala marangrang, faeba optic kabel, hasoa seea-le-le tse ling tse joalo.). Ho tloha ka lik'homphieutha li teng haufi le e mong le e tse ling tse, ho bopa netweke ho hokahanya lekane ka kabel bona le fetola e loketseng. Inthaneteng tsa lik'homphieutha ka marangrang ya khomphuta ya hao IPLs fana mong'a lona a mangata menyetla.

Types of dinetweke tseo ea moo ya khomphuta ya hao hangata abelana ka topology - le mokhoa oa tlohang lik'homphieutha mong ho e mong. The topology ke bath ea bohlokoa ea dinetweke tseo moo, kaha e laolwang ke tsela eo komponeng lipalo senotlolo hlahiswa tshebetso le tshebetso tšepahala.

Ka ba molemo ho kholo ka ho fetisisa ya netweke le phethile ho ea ka topology tsa "naleli" - mohloli o mong bohareng e amana le lik'homphieutha tse ling tsohle le ka ya netweke le.

Ho na le marangrang, thehoa ho ea ka topology tsa "lesale" - lik'homphieutha tsohle buisana letotong 'me qetellong bopa ntho tšoanang reng.

A mofuta oa boraro oa topology, tse bakiloeng ke dinetweke tseo ea moo k'homphieutha, bese topology - lik'homphieutha tsohle tse amanang ho kabel e le 'ngoe - ya data bese.

Ya khomphuta ya hao dinetweke kamoo ba sebetse, diprothokholo, 'me metsoako hardware lula ntse ba ntlafala' me pele.
