Yuav ua li cas yog lub motherboard nyob rau hauv koj lub computer

Motherboard - qhov no yog qhov tseem ceeb ntawm cov niaj hnub lub computer. Nws yog ib tug phaj ntawm insulating cov ntaub ntawv uas nrog wirings, uas muaj feem ntau ntawm cov computer qhov chaw thiab connectors. Lawv yuav tsum tau muab faib mus rau hauv sab nraud thiab sab hauv.

Sab nraud sib txuas yog siv los hloov xov xwm nrog lub ntiaj teb sab nraum. Cov terminals yog kev cob cog rua ib tug keyboard, taw ntaus ntawv "nas", monitor, tshuab luam ntawv thiab lwm yam peripherals. Tag nrho cov connectors yog mounted rau ntawm ntug ntawm lub motherboard, yog li ntawd thaum koj nruab nws nyob rau hauv lub computer lawv mus rau sab nraum qab phab ntsa. Los ntawm ib tug sab nraud LAN kev twb kev txuas (Local Cheeb Tsam Network, zos Cheeb Tsam Network) computer mus rau hauv lub zos (lub zos) network thiab hauv Internet.

Tam sim no, muaj yog ib tug ib txwm mus txo tus naj npawb ntawm cov hom ntawm cov sab nraud connectors. Piv txwv li, cov laus chaw nres nkoj LPT (thaum uas tig mus) thiab COM (serial) yog tsis ntsia rau ntau ntau lub tshiab board. Cov ports muaj ib tug uas tsis muaj cov ntaub ntawv tus nqi thiab moog USB chaw nres nkoj (Universal Serial Bus, Universal Serial Bus).

Motherboard tseeb uas muaj USB 3.0 specification. Paub qhov txawv ib tug qhov chaw nres nkoj specification yuav ua tau rau cov xim xiav connector. Heev pab tau USB chaw nres nkoj feature yog hais tias nws tso cai "kub swapping". Tus ntaus ntawv (e.g., ib tug laser los yog number case dav hlau tshuab luam ntawv) tej zaum yuav hloov "rau tus yoov", tsis muaj tig tawm nws lub suab, los yog computer.

Qhov no yog tiav los ntawm ib tug tshwj xeeb connector tsim. Nyob rau hauv cov ntaub ntawv no, lub hwj chim hu (lub xeem connector terminals) yog kev cob cog rua thawj thiab kaw tas los. Cov laus connectors rau "nas" twj remote controls thiab PS / 2 yuav tsis hloov mus "rau tus yoov", nws yog yuav puas ntaus ntawv los yog txawm kev puas tsuaj ntawm cov motherboard.

Internal connectors txog rau motherboard yuav ua tau ntawm ob peb hom:

• Rau cov processor,

• Nco,

• rau expansion phaib,

• discrete (zuag-connectors).

Tam sim no, computers siv nyob rau hauv feem ntau ntawm cov mob ob tug npe processors - AMD thiab Intel. Processors txawm ib tug hauv chav kawm ntawv, tab sis txawv tuam txhab uas muag muaj sib txawv nyob rau hauv lub architecture thiab qhov sib txawv tus naj npawb ntawm pins, yog li lawv yog tsis interchangeable. Thiab lub processor Intel yuav tsis muab tso rau hauv lub rooj tsavxwm, tsim rau AMD processors.

Txawm li cas los, lub Rooj Tswjhwm Saib yog ua kom ib tug connector (socket) txhawb ntau processors ib ruaj. Nco ntsoov tias lub processors yog qhov tseeb uas los ntawm ntau tshaj li 1,000 terminals.

Lub motherboard kuj muaj ob peb (tsawg kawg yog ob) connectors (slots) rau lub cim xeeb modules. Nco modules muaj kev sib cuag nrog ob sab thiab ob hom lag luam - lub projections nyob rau sab sab (qhov chaw uas cov neeg) thiab sab. Lateral projections pab kom txhim kho tau qhov modules nyob rau hauv lub connector. Lub sab hauv qab - ib tug "foolproof".

Qhov tseeb yog tias tam sim no lub cim xeeb yuav ua tau ntawm ob peb hom (rau tsev neeg thiab cov chaw ua hauj lwm computers siv los ntawm DDR2 thiab DDR3 nco modules), txhua tus uas sau nyob rau hauv nws zaus thiab voltage. Yog li ntawd, "tsis yog koj module" yuav tsis muab tso rau hauv lub connector. Qhov no tiv thaiv tsis pub tso zis rau ntawm lub cim xeeb modules thiab lub motherboard los ntawm lub system.

Tiv tauj modules yog coated nrog ib tug conductive txheej (kub, kuv yuav tsum hais tias, tsis siv), tiam sis tej zaum cov kev sib cuag yog tseem weakening. Qhov no tej zaum yuav ua rau malfunction ntawm lub computer. Nws yog pom zoo kom tshem tawm cov unit, so nws tiv tauj nrog isopropyl (los yog ethyl cawv) thiab rov ntxig rau nws rau hauv lub qhov.

Muaj internal connectors rau expansion boards. expansion card - yog tas modules mus cuag lub functionality ntawm ib tug computer. Yog li, lub graphics card (los yog card) nws muaj nws tus kheej nyob rau hauv-board processor thiab graphics nco. Nws yuav siv sij hawm tso zis rau ntawm nraaj ntaub ntawv rau lawv tus kheej, yog li relieving lub CPU thiab RAM cim xeeb ntawm cov computer.

Nws yuav tsum tau muab sau tseg tias expansion card connectors yog muaj nyob rau hauv ib qho qhib-architecture computers (kuj hu ua IBM tshaj). Computers lub tuam txhab «Kua» tau kaw architecture. Tam sim no, graphics card, siv lub connector PCI Express.

Yog xav paub ntxiv kom paub meej txog tus ntaus ntawv computer motherboard yuav muaj nyob rau hauv tsab xov xwm "Yuav ua li cas yog lub motherboard" rau ntawm qhov chaw "Computer thiab lub neej". Muaj koj yuav saib tau cov duab thiab cov zoo zoo.
