Yintoni ikhadi network?

Nayiphi na inkqubo yekhompyutha mihla imbaxa lwezixhobo lokunxibelelana, ngalinye elenza umsebenzi ethile. Umzekelo, ikhadi yenzelwe ukujikelezisa iimpawu ukuba zitshintshele kwi esweni image; umsindo - yomsindo; ikhadi kwinethiwekhi - ukuqhagamshela iinkqubo wecomputing ezininzi kwaye njalo njalo. Bonke bephela aqokelelwa umfanekiso inkqubo ye khompyutha yakho. Kungenxa yoko le nto kubaluleke kangaka ukuqonda awohluke yamacebo, ukwazi iimpawu zabo ezisisiseko. Isihloko nqaku namhlanje yethu yeyona ikhadi network.

Okwangoku, imarike inika iinguqulelo ezininzi izixhobo ezinjalo eziya kwahluka phakathi ngokwabo ngumvelisi, kusetyenziswa chip unxibelelwano, ngesantya ubuninzi ukusebenza, indlela Uyamano motherboard computer kunye ugqithiso lwedata esiphakathi. Makhe sihlolisise ingongoma nganye ngokweenkcukacha.

umenzi

Kukho iinkampani ezininzi ukuvelisa izixhobo ezinjalo. Xa ukhetha kufuneka sinikele ingqalelo ekhethekileyo ukusebenzisa nj - kuba iimpawu zayo ukufumanisa amathuba busebenzisekayo. Ezi ingaba iinkampani iimveliso Realtek, Intel, Qualcomm, ie bonke abo abanenxaxheba ngokuthe ngqo ekuveliseni izixhobo zonxibelelwano. Ngaphandle kwento yokuba ngumsebenzi ophambili izixhobo nguye, "umthi" okufanayo ikhadi womnatha (nokulawula inkqubo yomsebenzi kwinkqubo yokusebenza) kbavelisi ezohlukeneyo iimpawu ezahlukeneyo olongezelelweyo. Umzekelo, ulawulo lwamandla onengqondo, indlela bavuke processing umyalelo, ubungakanani isakhelo bembonisa engekho kuzo zonke izigqibo kunye nokuphunyezwa ingahluka. Ukuba ikhadi womnatha kufuneka inkxaso iimpawu ezithile lokukhetha kufuneka wasondela kuphela ukulungiselela kakuhle. Kuba abasebenzisi eziqhelekileyo iya sihambelane nayiphi ikhadi womnatha, okona kubaluleke kakhulu, ukumisela iirhafu ezifanelekileyo yaye isondela umgaqo transfer.

Ukongeza, iindleko yokwenza efana ezisebenza ubukhulu becala kuxhomekeke kumenzi. Xa uthenga imveliso developer amanqugwala kudla kufuneka ahlawule 'igama. " Kukholelwa ukuba ukuthembeka kwezi modeli ingaphezulu mali. Oku ngokungaphelelanga kuyinyaniso. Kwangaxeshanye, ikhadi womnatha D-Link (kwakunye nawuphi na omnye wabenzi) zinokuthengwa ukuba imali ezahlukeneyo. Izizathu zoku siya kukunika ngezantsi.

Iimpawu hardware

Ukuze ngendlela ethile ukuze aphathe umsinga data lwedijithali, ikhadi womnatha owenza isixa esikhulu yokubala - yenza iipakethi ngokuhambelana nemigangatho, ulawula ugqithiso / ulwamkelo njalo njalo. Kwaye ngenxa yale njongo izibonelelo ezingundoqo iprosesa engundoqo. Yiloo nto xa isixa esikhulu data ezosulela inokubonakalisa nokuthoba jikelele. Ukulungisa oku chips oluthile ezinye iimodeli amakhadi womnatha bayakwazi ukusingatha ngokuzimeleyo umsinga data ngaphandle kokusebenzisa i CPU. Oku kubizwa ngokuba processing zekhompyutha. Kunokuba ngokupheleleyo okanye ngokungaphelelanga. Ngoko, kuba lo mbutho nje elula engaxabisi ikhadi womnatha isuti software-kolawulo, kodwa ke ngenxa iindawo ezintsonkothileyo Kucetyiswa ukuba ahlawule ingqalelo wayifanisa nobunzima kakhulu.

speed

Performance - yenye iimpawu ezingundoqo izixhobo ezinjalo. Ngokomlinganiselo, ikhadi nga ukuxhasa amazinga data ka-10, 100 no-1000 megabits ngomzuzu. Zonke izisombululo mihla, nto leyo esetyenziselwa ukudibanisa uhlobo USB RJ-45, ngaba iyahambisana omnye komnye, oko kukuthi enye intambo inye zingadityaniswa wayifanisa kunye mbps 10 no 1000. Kulo mzekelo, imithetho elandelwayo Ngokuzenzekelayo alungiswa ukuba kwisantya asezantsi. Ngoko ke, ukuba ufuna ukudibanisa ku kwinethiwekhi 1 Gbit amabini iikhompyutha, ngoko, ilifa iintambo eziyimfuneko kunye namakhadi, kube lula ukwenziwa. Noko ke, ukuba phakathi kwabo kukho into eliphakathi, ezifana switsha mbps-100, i-uqina zizonke ziza kuthunyelelwa kubo.

ngoLwesithathu

Kuba data transmission iintambo zingasetyenziswa (isibini ezijijekileyo), kunye sokuquqa kwerediyo. Amakhadi ezisebenzisa sigqibo ezintsha, ngokufuthi ukusebenza ngomgangatho Wi-Fi. Ngoku ithandwa kakhulu, njengoko networking lula kakhulu. ukudlulisela izinga xa usebenzisa i isitishi serediyo awudluli Megabits 300.
