11. Kev paub txog

Lub tsev kawm ntawv muaj ntau yam ntawm lub rooj tsavxwm Circuit Court thiab ntau yam ntawm nws.

Circuit Court Board

PCB cov ntawv cog lus Circuit Board yog qhov tseem ceeb rau txhua lub computer boards. Nws tau ua ke ua ke los ntawm ntau cov khaubncaws sab nraud povtseg ntawm cov ntaub ntawv cob qhia, thiab sab hauv yog ua los ntawm cov ntawv ci khov. Feem ntau cov Board PCB Circuit Board muab faib ua plaub txheej. Sab saum toj thiab hauv qab ob txheej yog cov teeb liab. Qhov nruab nrab ob txheej yog lub dav hlau hauv av thiab lub hwj chim txheej. Hauv av thiab hwj chim txheej yuav muab tso rau hauv nruab nrab, xwv kom cov kab hluav taws xob tau yooj yim kho. . Qee cov laug cam uas muaj ntau tshaj tuaj yeem ncav cuag 6-8 txheej lossis ntau dua.

2. Sab Choj Chip

Chipset yog qhov tseem ceeb ntawm cov niam ntawv. Nws feem ntau muab faib rau hauv Northbridge thiab Southbridge raws li txoj hauj lwm ntawm lub niam ntawv. Piv txwv li, Intel's i845GE chipset yog 82845GE.

GMCH North Chip Chip thiab ICH4 (FW82801DB) Sab Hnub Choj Chip; thiab VIA

KT400 chipset yog tsim los ntawm KT400 North Chip Chip thiab Choj Chip Chip xws li VT8235 (tseem muaj cov khoom ntiag tug, xws li SIS630 / 730, thiab lwm yam.), Uas Choj Nias Chip yog tus choj loj, uas feem ntau siv tau nrog sib txawv Choj Chips kom tau ntau lub zog thiab kev ua haujlwm.

3. Sab Choj Chip

Choj sab qab teb choj yog siv los txuas nrog I / O cov cuab yeej thiab ISA cov cuab yeej, thiab yog lub luag haujlwm rau kev tswj kev cuam tshuam thiab DMA raws kom ua txoj haujlwm ua haujlwm ntau dua. Nws muab KBC (Keyboard Controller), RTC (Cov sij hawm ntawm lub sij hawm tiag tiag), USB (Universal Serial Bus), Ultra

Txhawb nqa DMA / 33 (66) EIDE cov ntaub ntawv sib kis thiab ACPI (Advanced Energy Management), thiab lwm yam, ze rau ntawm PCI qhov.

4. CPU ntsawb

Lub ntsawb qhov CPU yog qhov chaw nruab nrab ntawm lub tshuab hluav taws xob. Mainstream CPU cov khoom muaj xws li Socket370 thiab qhov (Socket).

478, Qhov (Socket 423) thiab qhov (Socket) ntau ntau. Ntawm lawv Socket370 txhawb PIII thiab tshiab Celeron, CYRIXIII thiab lwm yam kev sib tshaj; Qhov (Socket)

Lub 423 yog rau cov qub Pentium 4 processor, thaum lub qhov rooj 478 yog rau tam sim no mainstream Pentium 4 processor.

5. Nco qhov ntsej

Lub qhov nco yog qhov chaw nco tau nyob rau hauv daim ntawv qhia lub niam tswv yim. Cov kev nco no feem ntau yog SDRAM nco, DDR nco qhov qhib, thiab lwm yam EDO thaum ntxov thiab cov ntsiab lus tseem ceeb hauv RDRAM nco. Nws yuav tsum tau sau tseg tias txawv qhov nco tau muaj ntau lub pins, voltages, thiab kev ua haujlwm ua haujlwm. Sib txawv txawv tsis tuaj yeem siv siv los hloov chaw sib txawv. Rau 168 kab SDRAM nco thiab 184 kab ntawm DDR

SDRAM nco, lub ntsiab sib txawv hauv qhov tsos yog tias muaj ob tus gaps hauv SDRAM nco ntiv tes kub, thiab tsuas muaj ib DDR SDRAM nco.

6.PCI qhov

PCI (kev tiv thaiv ntawm tus kheej)

Interconnect) Lub tsheb npav uas yog ib lub tsheb npav uas tau pib los ntawm Intel Corporation. Nws txhais cov npauj npav 32-ntsis thiab tuaj yeem nthuav rau cov khoom 64. Nws muab ib qho kev sib txuas ua ke rau cov ntawv teev lus graphics, suab phaib, cov ntawv teev lus network, TV phaib, Luam thiab lwm yam khoom siv. Nws cov kev khiav hauj lwm zaus yog 33MHz thiab qhov siab tshaj plaws kev xa tawm yog 132 MB / s.

7.AGP qhov

AGP graphics qhov chaw nres nkoj acceleration (Accelerated Graphics

Chaw nres nkoj) yog ib qho interface rau 3D accelerator phaib (3D graphics phaib). Nws txuas ncaj qha mus rau sab qaum teb choj ntawm lub motherboard, thiab tus interface tso cai rau tus yees duab ua haujlwm ncaj qha mus rau lub cim xeeb ntawm lub kaw lus, tsis txhob muaj qhov kev kaw lus ntawm lub voj voog txuas ntawm PCI tsheb, nce qhov kev sib kis ceev ntawm cov 3D graphics cov ntaub ntawv, thiab txo qhov cim xeeb ntawm qhov tsis nco txaus. Lub kaw lus tseem ceeb hauv lub xov tooj hu tau, yog li nws muaj kev hloov siab heev, uas tsis zoo rau lub npav xws li PCI. Lub AGP interface tau muab tso tawm ntau hauv AGP1X / 2X / PRO / 4X / 8X.

8.ATA interface

Lub ATA interface yog siv los txuas xws li kev nyuaj disks thiab qhov muag tsis pom kev. Mainstream IDE interface yog ATA33 / 66/100/133, thiab ATA33 tseem hu ua Ultra.

DMA / 33, ib qho kev sib txuas ntawm DMA synchronous tsim los ntawm Intel Corporation. Traditional IDE transmissions siv ib sab ntawm cov ntaub ntawv txhais lub teeb liab kom xa cov ntaub ntawv, thaum Ultra.

DMA siv ob sab ntawm cov ntaub ntawv txhais lub cim thaum xa cov ntaub ntawv, yog li nws muaj 33MB / S hloov ceev.

9. qhov khau looj xim tsav tsheb

Lub plhaub tsav interface muaj tag nrho ntawm 34 pins. Raws li lub npe implies, nws yog siv los coj mus cuag ib lub tshuab disk ntog. Nws cov duab yog luv dua cov IDE interface.

10. Lub hwjchim thiab lub hwjchim muaj hwjchim

Lub hwj huam ntawm qhov hluav taws xob tsuas yog muaj ob hom ntawm lub hwj chim thiab ATX fais fab, thiab qee qhov motherboards muaj ob qho tib si nyob rau tib lub sijhawm. Cov ntawv thov siv qhov ntsawb (socket applications) tau raug tshem tawm ntev lawm. Lub 20-port ATX hwjchim qhov hluav taws xob txais cov txheej txheem los tiv thaiv kev tsim, uas tsis mob lub niam ntawv zoo li lub hwj chim. Tsis tas li ntawd, feem ntau yog lub hwj huam thiab qhov hluav taws xob ntawm qhov hluav taws xob ntawm lub niam tsev nyob ze ntawm lub hwj huam.
