Network adapter - piav qhia thiab daim ntawv thov

Internet nyob ntev los no, tab sis twb tswj tau "loj hlob ib tug" kev cov ntsiab lus uas, xws li xws li ib tug router, rooj vag, network adapter. Tag nrho cov npe no xa mus rau txoj kev thiab hom ntawm Internet kev twb kev txuas, thiab tej zaum kuj muaj tib lub ntsiab lus. Cov feem ntau txhais tau tias ntawm egress mus rau lub network - lub network card los yog adapter. Nws ua hauj lwm pab raws li ib tug transmitter ntawm lub hwj chim qaum thiab lub computer system.

Muaj ntau ntau hom ntawm network phaib, tab sis lawv muaj tib lub muaj nuj nqi. Firstly, lawv kis tau thiab txais tau cov ntaub ntawv rau sib sau ua ke rau hauv lub pob khoom. Lawv tsim nyob rau hauv lub tsis nco thiab lub computer adapter communicates ntawm lub cim xeeb. Nyob rau hauv tas li ntawd, Internet maps encode los yog txhais cov ntaub ntawv siv thaum uas tig mus los yog series cov lis dej num (nyob ntawm seb cov ntaub ntawv tau txais los yog kis tau).

Los ntawm cov qauv ntawm cov kev koom ua ke ntawm lub network adapter yog muab faib ua peb yam: sab nraud, sab hauv thiab ua tau. Yuav kom muaj xws li ib tug ua-nyob rau hauv adapters uas yog ib feem ntawm lub motherboard. Connector uas txuas lub hwj huam qaum, thiab ua ntaub ntawv nti nyob neposredstveno tsis tu ncua nyob rau hauv lub PCB, thiab cov nta ntxiv ua-nyob rau hauv adapter siv los ntawm lub CPU. Cov cards yog nruab nrog yuav luag tag nrho cov motherboards.

Internal Adapter - ib tug nti ntsia tau rau hauv lub system unit. Nws yog kev cob cog rua ntawm connectors mus rau lub motherboard PCI, PCIe los yog ISA. Network card Sab nraud hom yog muab ntim rau hauv ib lub hnab yas casing thiab kev cob cog rua rau lub system ntawm USB-interface. Tej cards yog siv qhov muaj yog tsis muaj built-nyob rau hauv los yog ib tug nrog adapter, los yog nws yog lawm.

Ntau ntev los no, lub Internet card yog tsuas txhais tau tias ntawm kev nkag tau mus rau lub network. Maj mam, li cas los xij, qhov no ntaus ntawv tau raug supplanted los ntawm wireless kev sib txuas lus. Ib tug ntawm lawv - yog ib tug wireless network adapter (los yog Wi-Fi). Nyob rau hauv qhov tseeb, Wi-Fi - ib tug kav hlau txais xov uas tso cai rau koj mus txuas rau lub network "saum huab cua". Cov adapters yog tseem sab nraud, sab hauv thiab kev. Ua-nyob rau hauv Wi-Fi kev mus rau hauv lub motherboard. Domestic feem ntau yog "hybrid" kav hlau txais xov thiab ib tug network card. Sab nraud Wi-Fi-adapter yog heev uas zoo sib xws rau qhov tam sim no cob xub 3G-modems. Lawv yuav feature ib tug kav hlau txais xov - los yog ua los txawv teb chaws - lub caij nyoog kawg no muaj ib tug ntau dua ceev.

Network phaib yog distinguished tsis tau tsuas yog los ntawm tus txheej txheem ntawm kev koom ua ke, tab sis kuj nyob rau hauv nws cov tuition. Ib txhia adapters muaj ib tug socket rau nruab lawv tus kheej software. Lwm yam txawv lo lus ntev ntawm lub system tsheb npav los yog lub xub ntiag ntawm ntxiv ports. Muaj yog ib qho hauv internet card, RAM thiab nruab nrog LEDs. Tsis tas li ntawd, lub network adapter muaj ob peb hom differing los ntawm txoj kev ntawm kev sis raug zoo nrog cov computer system thiab kev khiav hauj lwm hom. Sib tham nrog cov card system yuav yog ntawm cov tswj lub tsheb npav thiab ntawm ncaj qha nco saib. Los ntawm kev khiav hauj lwm lub xeev ntawm cov pab kiag li lawm yog muab faib ua ob hom: ib tug cyclic tswv yim / tso zis, thiab muab qhia kev nco.

Los ntawm cov zog, cov kev ceev ntawm lub Internet nyob rau ntawm daim card. Network adapter uas muaj tsawg kawg yog ib nrab ntawm cov nta muab ib tug ceev heev thiab xis nkag tau mus rau lub network.
