Lub network adapter, tseem hu ua NIC (network interface card), yog cov khoom siv kho vajtse uas txhais cov ntaub ntawv hauv koj lub tshuab rau hauv cov teeb liab uas tuaj yeem hla lub network. Hluav taws xob pulses down ib tug tooj liab cable, lub teeb los ntawm fiber ntau, xov tooj cua nthwv dej los ntawm huab cua - uas txhais txoj hauj lwm yog dab tsi lub adapter ua.
Txhua lub cuab yeej koj muaj ib qho. Koj lub xov tooj, koj lub laptop, koj lub thawv NAS hauv lub txee dai khaub ncaws. Ib txhia yog soldered mus rau lub motherboard ntawm lub Hoobkas. Lwm tus yog daim npav uas koj tau muab tso rau hauv PCIe bay lossis me me USB dongles koj ntsaws thaum lub tsim - hauv kev xaiv tsis txiav nws ntxiv lawm.
Phau ntawv qhia no feem ntau yog tsom rau cov neeg xav tauxaivib qho adapter - seb qhov ntawd puas yog kho dua tshiab lub chaw ua haujlwm hauv tsev, txheeb xyuas lub server tsim, lossis daws teeb meem vim li cas lawv qhov kev sib txuas tam sim no xav tias qeeb. Peb yuav hla cov phau ntawv qhia kev sib txuas lus uas peb tuaj yeem ua tau thiab tsom mus rau qhov tseem ceeb thaum koj tab tom yuav khoom lossis kuaj xyuas qhov teeb meem.
Yuav ua li cas Network Adapters ua haujlwm tiag tiag
Peb yam tshwm sim txhua zaus cov ntaub ntawv tawm hauv koj lub tshuab los ntawm lub network adapter.
Ua ntej, lub adapter converts koj cov ntaub ntawv mus rau hauv ib tug transmittable teeb liab.Koj lub computer xav hauv digital - ones thiab zeros khaws cia hauv nco. NIC yuav siv cov ntaub ntawv digital thiab hloov nws mus rau txhua qhov nruab nrab ntawm koj lub network siv. Rau tus qauv Ethernet kev twb kev txuas, uas txhais tau hais tias hluav taws xob voltage hloov nyob rau hauv lub copper khub nyob rau hauv koj Cat6 cable. Rau fiber ntau, nws yog pulses ntawm laser teeb. Rau Wi-Fi, nws yog modulated xov tooj cua nthwv dej. Txawv nruab nrab, tib txoj hauj lwm.
Qhov thib ob, nws qhwv txhua yam hauv pob ntawv.Cov ntaub ntawv nyoos tsis tuaj yeem muab pov tseg rau hauv ib lub xov hlau. Lub adapter teeb tsa koj cov ntaub ntawv raws li Ethernet raws tu qauv (txhais tau nyob rau hauv IEEE 802.3 tus qauv tsev neeg) - ntxiv qhov chaw thiab qhov chaw nyob MAC, yuam kev- xyuas CRC qhov tseem ceeb, thiab cov khoom sib txuas uas pab qhov kawg tau txais paub qhov twg ib pob ntawv xaus thiab lwm qhov pib. Xav txog nws zoo li muab tsab ntawv tso rau hauv ib lub hnab ntawv nrog "los ntawm" chaw nyob, "rau" chaw nyob, thiab tus lej taug qab.
Thib peb, nws tswj ob - txoj kev tsheb.Koj lub adapter yog ib txhij xa koj cov ntaub ntawv tawm sab nraud thiab mloog cov ntawv xa tuaj rau nws. Ntawm lub network tsis khoom, nws tseem tuav kev sib tsoo kom tsis txhob sib tsoo (rau Wi-Fi) lossis tag nrho - kev sib tham dua (rau Ethernet), ua kom cov ntaub ntawv ntws mus rau ob qho tib si.
Qhov tseem ceeb nws. Txhua lwm lub tswv yim sib tham - IP chaw nyob, DNS, routing, firewalls - tshwm sim hauv software txheej saum lub adapter. NIC tsuas yog saib xyuas lub teeb liab lub cev thiab cov ntaub ntawv -txuas txuas. Hauv OSI qauv cov ntsiab lus, qhov ntawd yog Txheej 1 thiab Txheej 2.
Daim ntawv ceeb toom ceev ntawm MAC Chaw Nyob
Txhua NIC nkoj nrog qhov tshwj xeeb 48-ntsis MAC chaw nyob tau hlawv hauv lub hoobkas. Qhov no yog lub hardware-theem identifier uas distinguishes koj adapter los ntawm txhua lwm yam nyob rau hauv lub zos network. Thaum koj lub router xa ib pob ntawv rau koj lub tshuab tshwj xeeb, nws yog qhov chaw nyob MAC nws siv los nrhiav koj - tsis yog koj qhov chaw nyob IP (qhov no yog qhov kev txhawj xeeb siab dua).
IEEE tswj MAC chaw nyob, muab cov chaw nyob rau txhua qhov chaw tsim khoom. Yog li tsis yog, koj lub adapter thiab koj tus neeg nyob ze lub adapter yuav tsis qhia MAC chaw nyob, txawm tias koj yuav tib lub npe tib hnub. Hais tias, MAC chaw nyobua tauraug spoofed hauv software, uas yog qee zaus muaj txiaj ntsig rau kev daws teeb meem lossis kev ceev ntiag tug - tab sis qhov ntawd yog lub ntsiab lus rau lwm hnub.

"Nws txuas, tab sis qhov ceev tsis yog lawm"
Qhov no feem ntau txhais tau tias nws pib- kev sib tham tau daws ntawm qhov nrawm dua li qhov xav tau. Yog tias koj muaj Gigabit adapter tab sis Tus Thawj Tswj Ntaus Ntawv qhia tau hais tias 100 Mbps txuas nrawm, cable yuav luag txhua tus neeg ua txhaum. Cat5 (tsis yog Cat5e) maxes tawm ntawm 100 Mbps. Cov cables puas tsuaj - tshwj xeeb tshaj yog cov uas muaj kinked lossis crushed khub - kuj tuaj yeem yuam kom txo qis. Xyuas qhov chaw nres nkoj hloov ib yam nkaus; qee qhov tswj kev hloov pauv muaj rau - qhov chaw nres nkoj ceev txwv uas tej zaum yuav raug teeb tsa tsis raug.
"Nws ua haujlwm tab sis txuas ntxiv"
Rau Wi-Fi:Tshawb xyuas Windows fais fab kev tswj chaw ua ntej. Mus rau Device Manager → koj Wi-Fi adapter → Properties → Power Management → uncheck "Cia lub khoos phis tawj tua lub cuab yeej no kom txuag hluav taws xob." Qhov kev teeb tsa no ua rau muaj tus lej tsis sib xws ntawm Wi-Fi poob, thiab nws tau qhib los ntawm lub neej ntawd ntawm ntau lub laptops. Yog tias qhov ntawd tsis kho, sim hloov ntawm 2.4 GHz band mus rau 5 GHz lossis 6 GHz (tsawg congestion), lossis hloov koj lub router Wi--Fi channel kom tsis txhob sib tshooj nrog cov neeg nyob ze.
Rau wired:Nquag tee ntawm tooj liab Ethernet feem ntau txhais tau hais tias lub cable nrog marginal kev ua tau zoo - nws ua haujlwm thaum txhua yam zoo tagnrho tab sis poob thaum cov xwm txheej hloov me ntsis (kub, qhov chaw nyob ze EMI). Hloov cov kab hluav taws xob nrog qhov paub zoo - zoo thiab sim. Rau cov fiber ntau, cov tee me me tuaj yeem qhia tau tias cov khoom siv qias neeg, fiber ntau khoov uas tshaj qhov tsawg kawg nkaus khoov vojvoog, lossis lub transceiver mus txog qhov kawg - ntawm - lub neej. Lub ntsuas hluav taws xob kho qhov muag nyeem tuaj yeem paub meej tias koj puas tau txais lub teeb liab txaus.
"Adapter tsis lees paub los ntawm OS"
Rov kho daim npav. Fais fab tag nrho txoj kev tawm (tsis pw tsaug zog - tag nrho kaw, qhov zoo tshaj plaws unplug PSU rau ob peb feeb), qhib rooj plaub, rub daim npav, rov ua kom ruaj khov hauv PCIe qhov. Yog tias qhov ntawd tsis ua haujlwm, sim lwm qhov PCIe. Muaj qee zaus, qhov teeb tsa BIOS / UEFI tej zaum yuav muaj qhov tsis taus lossis muaj teeb meem nrog lwm daim npav. Kuj xyuas seb koj lub BIOS puas muaj qhov teeb tsa los lov tes taw onboard NIC - yog tias koj tab tom sim siv qhov tsim - hauv adapter thiab nws tsis tshwm sim, qhov no yog qhov ua rau.
Kev tu yog tho txawv tab sis tseem ceeb
Peb yam ua kom lub network adapter ua haujlwm zoo nyob rau lub sijhawm ntev:
Khaws cov tsav tsheb tam sim no.Tsis yog txhua tus tsav tsheb hloov tshiab yog qhov tseem ceeb, tab sis kev ruaj ntseg thaj ua rau thaj thiab kev txhim kho kev ua tau zoo ua ke. Tshawb xyuas cov kev hloov tshiab txhua ob peb lub hlis, lossis teeb tsa lawv pib - hloov tshiab yog tias koj lub chaw tsim khoom txhawb nqa nws. Intel's Driver & Support Assistant yog qhov tsim nyog rau qhov no.
Cia nws txias.Internal NICs - tshwj xeeb tshaj yog 10G thiab siab dua - ua kom sov. Xyuas kom koj rooj plaub muaj qhov tsim nyog airflow. Kuv tau pom 10G NICs thermal-thov rau hauv cov cua tsis zoo, txiav tawm hauv ib nrab uas tsis muaj lus yuam kev los piav qhia nws.
Khaws fiber ntau kom huv si.Yog tias koj muaj kev sib txuas ntawm fiber ntau, qhov no yog ib qho khoom tu loj tshaj plaws. Siv lub kaus mom plua plav ntawm txhua qhov chaw nres nkoj tsis siv. Ntxuav cov connectors txhua zaus koj unplug thiab reconnect lawv. Rau kev txhim kho mus tas li, kev nyeem cov ntsuas hluav taws xob hauv lub sijhawm (ib xyoos ib zaug yog qhov zoo rau kev teeb tsa feem ntau) pab ntes degradation ua ntej nws ua rau muaj kev puas tsuaj. Lub sij hawm kho qhov muag -domain reflectometer (OTDR) kuaj yog tus qauv kub rau kev kuaj xyuas cov teeb meem fiber ntau, tab sis qhov ntawd yog cov cuab yeej tshwj xeeb - koj tus neeg cog lus cabling lossis ISP tuaj yeem daws nws.
FAQ
Q: Qhov txawv ntawm NIC thiab router yog dab tsi?
A: NIC txuas koj lub cuab yeej mus rau lub network. Lub router txuas cov tes hauj lwm ua ke (feem ntau koj lub network hauv zos rau koj lub ISP lub network) thiab ua kev txiav txim siab txog qhov twg pob ntawv yuav tsum mus. Koj NIC tham nrog lub router, tsis yog hauv internet ncaj qha.
Q: Kuv puas tuaj yeem nruab ntau dua ib lub network adapter?
A: Yog lawm. Nws yog ib yam nyob rau hauv servers (rau redundancy, link aggregation, los yog cais kev tswj thiab cov ntaub ntawv khiav mus rau txawv subnets) thiab tsis txawv nyob rau hauv desktops ib yam nkaus thiab. Koj tuaj yeem muaj qhov ua tau -hauv Ethernet NIC, PCIe fiber ntau daim npav, thiab USB Wi-Fi adapter txhua tus khiav ib txhij yog tias koj cov ntaub ntawv siv hu rau nws.
Q: Puas yog "Ethernet" zoo ib yam li "wired"?
A: Ethernet yog raws tu qauv, tsis yog hom cable. Koj tuaj yeem khiav Ethernet hla tooj liab (Cat5e, Cat6, Cat6a) lossis tshaj fiber ntau. Thaum tib neeg hais tias "Ethernet cable," lawv feem ntau txhais tau tias yog tooj liab patch cable nrog RJ-45 connectors - tab sis technically, fiber ntau thaj qaum nqa 10G Ethernet kuj yog "Ethernet."
Q: Dab tsi yog qhov zoo tshaj plaws adapter rau kev ua si?
A: Ib qho kev sib txuas ntawm Gigabit. Qhov ntawd yog nws. Kuv paub txog kev lag luam rau kev ua si- cov ntawv teev npe network qhia lwm yam, tab sis rau lub hom phiaj latency, ib qho Gigabit NIC uas zoo (xws li ib qho uas twb muaj lawm ntawm koj lub motherboard) yuav ua tau zoo ib yam rau "gaming" NIC uas raug nqi peb zaug ntau npaum li cas. Qhov tseem ceeb tshaj plaws yog koj qhov kev txuas mus rau lub router: siv Ethernet hloov Wi-Fi, siv Cat5e lossis zoo dua cable, thiab xyuas kom koj lub router tsis yog lub hauv paus. Yog tias koj tiag tiag yuav tsum siv Wi-Fi, tau txais Wi-Fi 6E adapter nrog tus kav hlau txais xov sab nraud - band 6 GHz yog qhov muaj txiaj ntsig tsawg dua 5 GHz hauv cov tsev tsev tuab tuab.
Q: Kuv puas xav tau cov cuab yeej tshwj xeeb rau kev sib txuas lus fiber ntau?
A: Yog, tab sis nws tsis yog txawv li nws suab. Koj xav tau NIC nrog qhov chaw nres nkoj SFP (lossis qhov hloov pauv uas muaj SFP chaw nres nkoj), lub transceiver module sib phim rau koj hom fiber ntau thiab nyob deb, thiab fiber ntau patch cords nrog rau txoj cai connectors. Rau kev teeb tsa cable, ntxivfiber ntau adapters, pigtails, thiab ib lub vaj huam sib luag. Yog koj tsis paub qhov twgconnector hom xaiv(LC vs. SC vs. MPO), LC duplex yog lub neej ntawd kev nyab xeeb rau yuav luag txhua yam niaj hnub.
Q: Vim li cas kuv lub Wi-Fi adapter tseem tsis txuas?
A: Xyuas peb yam hauv qhov kev txiav txim no: (1) Disable power management for the adapter in Device Manager, (2) update driver, (3) switch to the 5 GHz or 6 GHz band. Yog tias tsis muaj ib qho kev pab, qhov teeb meem no yuav yog ib puag ncig - ntau dhau kev sib tw Wi-Fi networks, kev cuam tshuam lub cev, lossis kev ncua deb ntawm router. Lub cuab yeej Wi-Fi daim ntawv ntsuam xyuas (xws li NetSpot lossis WiFi Analyzer) tuaj yeem qhia koj raws nraim li cas tshwm sim nrog lub teeb liab lub zog thiab channel congestion hauv koj qhov chaw.
Q: Lub network adapters kav ntev npaum li cas?
A: Hauv kuv qhov kev paub, lub sijhawm ntev heev. Internal NICs tsis tshua muaj kev ua tsis tau zoo - lawv tsis muaj qhov txav mus los, thiab feem ntau yuav dhau los ntawm cov motherboard uas lawv txuas nrog. Qhov tshwj xeeb yog fiber ntau transceivers, uas yog laser-raws li cov khoom siv nrog lub neej ntev (feem ntau ntsuas rau 50,000-100,000 teev, lossis kwv yees li 6-11 xyoo ntawm kev ua haujlwm tas mus li). Yog tias qhov txuas fiber ntau ruaj khov yav dhau los pib pom qhov ua yuam kev ntau ntxiv, lub transceiver tuag yog ib qho ua rau.
