Noocyada Networks Computer

Waxaa la og yahay in mid ka mid ah guulaha ugu weyn qarnigii la soo dhaafay ee ahaa abuuridda Dadka iyo horumarka degdeg ah teknoolajiyada macluumaadka - teknoolajiyada in, iyadoo la isticmaalayo kumbiyuutarrada iyo noocyo kala duwan oo shabakadaha computer, dukaanka, habka, diinta iyo wareejiyo xaddi badan oo macluumaad. Waxaa xusid mudan in sida boodi degdeg ah binu-aadmiga oo warbixin uu noqday suuragal ah keliya ka dib markii shabakadaha computer ayaa la abuuray.

Dhammaan noocyada kala duwan ee shabakadaha computer waa a collection of kombiyuutarada qaybiyey in ka badan meel gaar ah oo isku xidhan by channels khaas ah, kuu oggolaadaan in aad si ay u gudbiyaan xogta. Maanta shabakadaha computer hubkaas ayaa loo isticmaalaa, noocyo kala duwan oo shabakadaha computer ka hawlgala daafaha dunida iyo falgalaan kasta oo kale. fahamka Modern oo ka mid ah muuqaalada shabakadaha, ayaa keentay in kala soocidda ee mabda'a dhuleed. Sida laga soo xigtay soocidda waxaa ka mid ah noocyada sida shabakadaha computer:

Network Global Area (GAN) - shabakad caalami ah oo kombuyuutarro iyo shabakad ku yaalla qeybaha kala duwan ee dunida.

Area Network Wide (WAN) - shabakadaha ballaaran in lagu biiriyo shabakadaha computer at heerka of qaaradaha iyo dalalka;

Network Metropolitan Area (MAN) - shabakadaha kombiyuutarada iyo shabakadaha gobollada iyo qaybaha kale ee maamulka masaafad dheer;

Network Area Local (LAN) - LAN, micnahoodu yahay is dhexgalka kombiyuutarada ku yaalaa meel fog gaaban - tusaale ahaan, dhismaha la mid ah gudahood.

WAN iyo MAN yihiin shabakadaha gobolka. Waxaa xusid mudan in taariikhda, kala qeybinta shabakadaha computer in WAN iyo MAN waa heer sare ah shuruud, sida hadda kasta network gobolka ka mid ah network kasta oo caalami ah.

Ururo badan in ay xiiseyneyso bixinta heer sare ah ilaalinta macluumaadka ka dhanka ah isfurnaashaha ka baxsan (tusaale ahaan, ciidamada, bangiyada, iwm), la abuuro shabakadaha iyaga u gaar ah, oo loo yaqaan shirkadaha. In shabakad shirkadaha ka mid ah waxaa laga yaabaa in tobanaan kun oo kombiyuutarada oo ku yaal meel fog ka badan midba midka kale, tusaale ahaan, in dalal kala duwan.

The ugu caansan ee dunida tiro ahaan yihiin shabakadaha computer maxaliga ah.

feature ugu muhiimsan waa wax macquul ah ee shabakadaha agtaada in ay ku xidhmaan kombiyuutarada cable iyagoon maciinsan wax channels for gudbinta xogta, isticmaalaan shabakadaha meelaha ballaaran (network telefoonka, cable fiber optic, warbaahinta raadiyaha iyo si bixi.). Tan iyo kombiyuutarada ku yaalaan meel u dhow midba midka kale, si ay u abuuraan shabakad in ay ku xidhmaan ku filan oo ay cable iyo qabsato sida. Kasbashada kombiyuutarada shabakada kombiyuutarka IPLs siiyaa ninkii neefka lahaa wax badan oo faa'iido.

Noocyada shabakadaha computer maxaliga ah sida caadiga ah la wadaagaan topology ah - hab ka mid ah isku xidha kombiyuutarada midba midka kale. topology waa dabeecad u muhiim ah oo shabakadaha maxalliga ah, tan iyo markii la go'aamiyo jidka tirooyinka muhiimka ah xarunta soo bandhigay qaab iyo isku halaynta hawlgalka by.

Faa'iidada ugu weyn ee shabakadda oofiyo sida ay topology ee "star" - in mid ka mid ah ilaha dhexe ku xiran oo dhan kombiyuutarada kale oo ku saabsan shabakada.

Waxaa network, sida uu sameeyay topology ah "giraanta" - oo dhan kombiyuutarada xiriiraan kasta oo kale ee taxanahan iyo ugu danbeyn u sameeyaan wax u eg giraan ah.

Nooca saddexaad ee topology, kuwaas oo abuuray by shabakadaha computer maxaliga ah, topology bas - oo dhan kombiyuutarada ku xiran yihiin hal cable a - bas xogta.

shabakadaha Computer, sida ay u shaqeeyaan, hab maamuuska, iyo qaybaha hardware si joogto ah la wanaajiyey iyo in la horumariyo.
