Yintoni ikhadi yenethiwekhi

ikhadi Network ixesha elide kwaba ingxenye enye efunekayo computer mihla, njenge mouse okanye ikhadi lesandi. Njengoko ngaphambili nje ezimbalwa unethamsanqa unako ukuthenga ezi izincedisi, kodwa ngoku ngaphandle ukuthetha malunga ngokupheleleyo inkqubo multimedia computationally ayikho imfuneko.

Ngaphambi kokuba sijonge ukuba ikhadi womnatha, masenze uhambo elincinane engqondweni ukuya 90 elikude. Enye yeendlela uthandwayo ulwazi lonaniso aba diskettes phakathi kweekhompyutha (iirhafu Internet baba phezulu, Dial-Up imodem eqhagamshelwe COM-izibuko, ukusebenza ngesantya esisezantsi). Nangona kunjalo, ukwandisa ubukhulu data eziphathwayo efunekayo akukho namnye kodwa diskettes eziliqela. Xa sikhumbula yimbonakalo ukuboniswa kwabo kumacandelo angafundekiyo, kuye kucace ukuba inkqubo kufuneka ziphuculwe. Kwakucacile ukuba kufuneka sibe nendlela ekuvumela ukuba umane yaye ngokukhawuleza ukuqhagamshela iikhompyutha, kwaye iye kuphakanyiswa. Qaphela ukuba isisombululo Kudala kwaziwa, kodwa hayi enobunzima.

Ngu motherboard eziplagwe isixhobo okhethekileyo - ikhadi network leyo abaxhotyiswe intambo ukudlulisela nayiphi na idata digital ukuya kwenye ikhompyutha mayixhotyiswe isixhobo efanayo. isantya sebhawudi amaxesha amaninzi ngaphezu fastest Dial-Up Modem. Ngenxa ikhadi womnatha umsebenzi ezifunekayo intambo yafakwa - kwaba 50 Ohm 'obhityileyo "kunye Ethernet" shinyi ". umabonakude Simple andizanga ngenxa eliphezulu ukumelana otshangatshangiswayo. ikhadi Network has a kakhulu "lusizi" isixhobo - uqhagamshelwano olusemgangathweni, intambo elungileyo, ukutshatisa stub terminator - yonke into kufuneka ayiyithobeli imigaqo.

Ngoku zininzi izinto ezitshintshileyo: intambo yafakwa indawo yi ezijijekileyo isibini USB, kwiplagi owakubhangisayo okunene, ukumelana ifuthe lifinyele, nto leyo evumela ukuba ukubuyisa kophuke twist elula. Kakhulu modified transmission protocol - kuqaliswa kabini ezipheleleyo (transmission ngaxeshanye / ulwamkelo kwi amakhadi womnatha ezininzi), kunye ngesantya esiphezulu ziye zaba eziqhelekileyo. Ngoku, ababoneleli ezininzi zifundisa ukufikelela kwi Internet nghapha isigqibo esinjalo, hayi modem. Hi ndlela leyi, imbonakalo USB unako ukugqiba udidi layo ngeenxa - yeyona ezinjalo kunye uxande (phantse njenge ifowuni) - a isibini ezijijekileyo.

Ngoko ikhadi womnatha - isixhobo ebonelela ugqithiso lwedata phakathi kwee computer nge ndlela eliphakathi (USB, amaza erediyo). Nangona kwiivenkile benokufunyanwa kwimaphu njengoko ikhithi eyahlukileyo, zonke motherboards ngoku sele ezinamaphepha soldered chip owenza yonke imisebenzi esisiseko lokufumana kanye nokuthumela uphawu.

Naliphi na ikhadi womnatha ujongano iqulethe inani "lwaluthungwa", ebizwa ngokuba yi-Mac dilesi ukuba uyakwazi ukubona oko. Ukuba kuyimfuneko, oko kufakwe software.

Kuxhomekeka amavili, ukwahlula PCI kunye nekhadi PCI-Express. Kwezinye iimeko, eluncedo zangaphandle uNic kanga kwizibuko USB.

Nangona zonke iimodeli zangoku ngezantya ukuvumela transfer ulwazi kwi Gbps 1, lo gama ifuna 100 Mbit / s, ekubeni kulo mzekelo intambo ithi ngezantsi.

Component umsebenzisi womnatha ifakiwe kwinkqubo umqhubi. Kufuneka ngekhompyutha kweli ziko lewebhu umphuhlisi kwaye ufake. Icebo "bona" ikhompyutha yakho kwaye basebenzisane nayo.
