Yuav ua li cas yog lub network adapter? Yuav ua li cas yog ib tug LAN adapter

Yuav ua li cas yog lub adapter network, qhov twg nws yog nyob thiab yuav ua li cas nws ua hauj lwm? Ntawm no yog cov tseem ceeb cov lus nug uas yuav tau tsim nyob rau hauv no tsab xov xwm.

Yog vim li cas yog nws yuav tsum tau?

Adapter - yog cov khoom uas muaj ib network txuas thiab lub cev ntau. Nws belongs rau lub peripherals. Nws ncaj qha ua num ua ke nrog cov ntaub ntawv kis tau tus mob nruab nrab. Tus adapter ntse daws qhov teeb meem ntawm txhim khu kev qha obmeta binary cov ntaub ntawv rau lwm mus. Vim hais tias nws yog tus maub los computer, nws thiaj li tawm tau nws cov hauj lwm nyob rau hauv cov kev tswj ntawm tus neeg tsav tsheb ntsia tau rau hauv lub operating system. Mounted raws li ib tug network adapter nyob rau hauv lub motherboard socket. Nws converts thaum uas tig mus codes uas yog siv nyob rau hauv ib lub computer, mus rau hauv ib tug kwj ntawm cov high-power Pib ntsais koj teeb, uas cov ntaub ntawv yog kis tau dua lub network. Yog li ntawd mus rau lawv muab tso rau pem hauv ntej qhov yuav tsum tau compatibility nrog lub network system operating thiab cov ntaub ntawv lub tsheb npav ntawm lub PC. Yuav ua li cas rau nruab ib tug network adapter rau cov motherboard?

hloov

Peb yuav tsum to taub dab tsi ib tug network adapter, koj tau tam sim no saib xyuas thiab kev npaj rau kev ua hauj lwm. Yog hais tias nws muaj raws li qhov PnP standard, lub hloov yog tsis siv neeg. Nyob rau hauv lwm rooj plaub no nws yog tsim nyog los manually ua hauj lwm nrog cov interrupt thov txoj kab thiab qhov chaw ntawm cov tswv yim / tso zis.

zog

Peb tau xav hais tias xws li ib tug network adapter, thiab yuav ua li cas nws yog configured, thiab tam sim no wb tham txog tej teeb meem uas daws nyob rau hauv cov kis los yog txais tos ntawm cov lus. Ib tug tag nrho ntawm cuaj:

1. Nqa galvanically cais los ntawm lub twisted khub los yog coaxial cable. Mas siv rau lub hom phiaj no muaj mem tes transformers, tab sis yog tau thiab kev siv cov optocouplers.
2. Kis (txais tos) ntawm cov ntaub ntawv. Lawv tuaj ntawm RAM mus rau lub adapter los yog los ntawm lub cim xeeb ntawm cov computer los ntawm tswv yim / tso zis channel thiab mus saib.
3. Buffering. Nws yog siv los ntsuas cov ntaub ntawv hloov lwm lub tsev tus nqi ntawm lub adapter los yog mus rau hauv nws nrog txoj kev uas lawv yuav kis tau tshaj lub network. Tsis tas li ntawd, thaum lub sij hawm ua cov ntaub ntawv uas yog cia nyob rau hauv tus tsis. Nws tso cai rau lub adapter mus ua hauj lwm nrog tag nrho pob ntawm cov ntaub ntawv. Tsis tas li ntawd, ua tsaug rau lub adapter yog ib tug ua kom sib haum cov ntaub ntawv nqi ntawm txawv tivthaiv LANs rau txhua lwm yam.
4. Tsim kom muaj ib tug pob. Network adapter cov ntaub ntawv yuav tsum tau muab faib mus rau hauv nyias muaj nyias kev blocks nyob rau hauv lub kis hom (los yog lawv nyob nraum mus nyob txais tos), ces mus rau teem caij rau lawv raws li ib tug ncej ntawm ib tug tej yam loj. Nws yuav tsum muaj li ntawm ob peb cov kev pab teb, nyob qhov twg rau qhov chaw nyob ntawm cov lo lus uas computer, thiab cov checksum ntawm tus ncej nyob rau hauv uas tus ntaus ntawv tau txais ib tug xaus txog seb tus tauj ntaub ntawv yog muaj tseeb.
5. Mus saib tau ib tug kev sib txuas lus channel. Tsis tas li ntawd nyob rau hauv nws "ciaj ciam" ib tug set ntawm cov kev cai uas yuav pab tau koj tau txais cov sij hawm los mus ua hauj lwm nrog ib tug kis tau tus mob nruab nrab. Nyob rau hauv tas li ntawd, lub adapter no tsis sib haum thiab tsom kwm tus txheej xwm ntawm lub network.
6. Qhia txog lub chaw nyob nyob rau hauv lub pob ntawv uas tau txais. Nws yuav tsum tau txiav txim los ntawm qhov chaw kawm keyboards, sewn nyob rau hauv qhov prom los yog cia nyob rau hauv ib tug tshwj xeeb register.
7. Hloov thaum uas tig mus code nyob rau hauv serial cov ntaub ntawv kis tau tus mob, thiab nws tuav lawv rov qab thaum lawv hloov dua siab tshiab txais tos. Ntawm no yog ib tug me me kev zam. Thaum lub active cov ntaub ntawv kis tau tus mob hom, cov kev sib txuas lus channel ntaub ntawv yog kis nyob rau hauv ib tug tshwm sim code.
8. Encoding / seev suab ntawm cov ntaub ntawv. Rau ntawm no theem lub tsim hluav taws xob Pib ntsais koj teeb uas yog siv los sawv cev rau cov lus qhia. Nyob rau hauv Feem ntau, ib tug Manchester encoding. Qhov no txoj kev tsis tau mus rau kis ib tug synchronization teeb liab mus rau paub txog qhov sawv daws yuav thiab zeros. Nyob rau hauv cov ntaub ntawv no, lub polarity hloov.
9. Tau txais los yog kis cov ntaub ntawv pulses.

Thiab network adapters thaum ua hauj lwm nrog cov kev tsim nyog software yuav paub txog thiab lis ib qho yuam kev uas tshwm sim vim cov neeg pluag kev ua tau zoo ntawm cov khoom, kev sib tsoo, los yog hluav taws xob cuam tshuam.

puag chaw nyob

Kuj hu ua lub cev. Part ntawm lub network adapters yuav siv lub computer lub cim xeeb yog ib tug tsis mus cia khoom thiab ntsaws cov ntaub ntawv packets. Base chaw nyob nyob rau hauv cov ntaub ntawv no yog hu ua ib tug hexadecimal tooj, uas qhia qhov chaw uas cov ntaub ntawv.

Ib suam ntawm txoj kev nkag tau mus rau cov feeb thiab qhov ib puag ncig

Lub network technology siv peb hom adapter:

1. Ethernet.
2. FDDI.
3. Token nplhaib.

Feem ntau, ib tug tej yam qauv ua hauj lwm tsuas yog nyob rau nws tus kheej network technology. Tab sis nyob rau tib lub sij hawm lawv yuav pab txhawb nqa, raws li ib tug txoj cai, ob peb txawv kis tau tus mob tawm. Piv txwv li, Ethernet yog ua hauj lwm nrog:

1. Fiber-optic cable.
2. Unshielded cov khub.
3. Coaxial cable.

Thaum tus ntaus ntawv yog kom ua hauj lwm nrog cov ib puag ncig rau cov uas nws yog Ameslikas tsim, lub converters thiab transceivers siv. Thiab network adapters yog distinguished los ntawm lub sab hauv cov ntaub ntawv lub tsheb npav:

1. PCI.
2. EISA.
3. ISA.
4. MCA.

Nyob rau dab tsi tsis lub network adapters yuav txwv kom muab zais?

Nyob rau hauv tas li ntawd rau tej no, nws tej zaum kuj yuav siv los yog:

1. Bus hom.
2. Tsis loj rau lub pob.
3. hloov mus rau lwm nqi.
4. Compatibility nrog txawv Microprocessors.
5. Ua tau zoo log.
6. Raws li hauv lub xub ntiag / tsis tuaj kawm ntawv ntawm cov kev siv ntawm ncaj qha nco saib.
7. connector tsim.
8. Hais tso zis ports / tswv yim thiab cuam tshuam kev thov.

Lub cev siv

Cia wb mus raws li ib qho piv txwv, xav txog ib tug network adapter rau lub qhov rais 7. Nyob rau hauv feem ntau yog ib feem lawv yuav tsum tau muab tso rau hauv motherboard. Tiam sis ntawm no TP-Link network adapter yog muab tau los tshaj li cov chassis. Qhov no yog tsis yog tsawg kawg vim nws functionality (lub peev xwm mus cuag ntau yam computers thiab tsim tau ib Wi-Fi network, uas yog, nws kuj yog ua hauj lwm pab raws li ib tug router, thiab cov router). Cov yav tas feature tso cai rau lub adapter rau tsim txawm ib tug me me lub zos cheeb tsam network, uas theem ua ke tag nrho cov pab kiag li lawm nrog rau cov tsim nyog interfaces yog nyob ze. Koj tseem yuav nrhiav tau USB-AC adapter. Nws yog feem ntau yog cov neeg muaj mobile network tswv. USB-AC adapter nyob rau hauv cov ntaub ntawv no zoo li ib tug flash drive, thiab txuas nws nyob rau hauv tib txoj kev. Rau cov ntaub ntawv kis tau tus mob no kuj siv 2G los yog 3G Internet. Ntawm no pej xeem ces nyob rau hauv pem hauv ntej ntawm peb tej zaum yuav qhia network adapter rau lub qhov rais 7. Los ntawm txoj kev, thiab yuav ua li cas lub ntaus ntawv yog siv nyob rau hauv ib phau ntawv? Yog hais tias peb tham txog Asus AC adapter, nws yuav tsum yog tam sim no nyob rau hauv lub pab kiag li lawm. Tib yam siv rau lwm yam laptops. Lub fact tias lawv yog tsim los siv nyob rau hauv ntau yam kev kawm, nrog rau mobile, thaum koj yuav tau ua hauj lwm nrog txhua leej txhua tus.

xaus

Yog li ntawd, peb pom hais tias xws li ib tug network adapter, hom muaj muaj thiab yuav ua li cas lawv yog siv nyob rau hauv xyaum. peb tseem pom ib qho piv txwv ntawm kev tsim ib cheeb tsam network nrog lawv. Nyob rau hauv xaus, peb yuav tsum hais tias lawv muaj peev xwm yuav nrhiav tau tsis tsuas yog nyob rau hauv tsev computers los yog laptops, tab sis kuj nyob rau hauv tus kws kho mob lub neeg rau zaub mov, uas muab Internet nkag tau mus rau lawv cov neeg siv. Tsuas no nws yog siv raws li ib tug hloov lub rooj vag.
