Qee lub khoos phis tawj, xws li slim thiab mini PCs, zoo li txawv dua li cov piv txwv saum toj no thiab lwm yam hauv qab no. Txawm li cas los xij, txhua lub khoos phis tawj muaj qhov tseem ceeb tib yam.
The Motherboard
Lub motherboard yog mounted rau hauv lub computer rooj thiab yog ruaj ntseg txuas ntawm me me screws los ntawm pre-drilled qhov. Tag nrho cov khoom nyob rau hauv lub computer txuas mus rau lub motherboard nyob rau hauv ib txoj kev los yog lwm yam.
- Expansion Cards: Motherboards feem ntau muaj ib tug xov tooj ntawm slots rau sab hauv peripheral phaib xws li video phaib thiab suab phaib mus cuag.
- Back Vaj Huam Sib Luag: Lub vaj huam sib luag rov qab txuas rau sab nraub qaum ntawm rooj plaub rau kev sib txuas rau cov khoom siv sab nraud.
- CPU & Memory Sockets: CPU thiab lub cim xeeb txuas ncaj qha mus rau lub motherboard ntawm CPU socket connector thiab nco qhov.
- Cia Drive Connectors: Cov khoom siv khaws cia tau txuas nrog cov cables rau lub motherboard. Muaj cov khoom sib txuas tshwj xeeb rau floppy drives, optical drives, thiab hard drives.
CPU thiab Memory
- CPU: CPU txuas ncaj qha mus rau CPU qhov (socket) ntawm lub motherboard nyob hauv lub computer. Lub CPU tau muab tso rau hauv lub qhov (socket) tus pin-sab-down thiab lub zog me me pab kom ruaj ntseg. Hauv qee cov duab ntawm lub motherboard, koj tuaj yeem pom tus kiv cua loj zaum saum CPU los pab cuam tshuam cov cua sov.
- Nco: Nco tau nruab rau hauv lub cim xeeb nyob ntawm lub motherboard. Cov no tau yooj yim pom los ntawm kev nrhiav cov pob khawm me me ntawm ob sab uas kaw lub cim xeeb hauv qhov chaw.
Khoom Devices
Cov khoom khaws cia xws li hard drives, optical drives, thiab floppy drives tag nrho txuas mus rau lub motherboard ntawm cables thiab txuas rau hauv lub computer.
- SATA Cables: Cov piv txwv no qhia txog ob lub hard disk drives uas txuas mus rau motherboard ntawm SATA cables rau kev nkag mus rau hard drive. Lwm hom kev sib txuas yog qhov qub PATA cable txuas, tab sis ib qho piv txwv tsis pom hauv daim duab no.
- Power Connectors: Lub zog los ntawm lub zog hluav taws xob xa mus rau ob lub tsav ntawm cov cables uas ntsaws rau hauv qhov chaw nres nkoj fais fab ntawm lub drives.
Pib Peripheral Cards
Daim npav Peripheral, xws li daim npav video, txuas mus rau qhov sib xws ntawm cov niam ntawv, hauv lub computer.
PCI Connector: Daim npav peripheral no yog tsim los nrog PCI connector thiab yuav tsum tau siv rau hauv hom no ntawm lub motherboard.
Lwm yam ntawm daim npav peripheral suav nrog daim npav suab, wireless network phaib, modems, thiab ntau dua. Ntau thiab ntau lub zog feem ntau pom muaj nyob rau hauv daim npav peripheral, xws li video thiab suab, tau muab tso ncaj qha rau ntawm lub motherboard kom txo tus nqi.
Sab nraud Peripherals
Feem ntau cov khoom siv sab nraud txuas mus rau lub motherboard txuas uas txuas mus rau tom qab ntawm rooj plaub.
- USB Ports: Cov khoom siv xws li nas, keyboards, lub koob yees duab digital, scanners, thiab cov tshuab luam ntawv feem ntau txuas rau motherboard ntawm USB ports.
- LAN Chaw nres nkoj: Lub chaw nres nkoj LAN yog siv los txuas lub PC mus rau lub network hauv zos lossis rau kev pabcuam hauv internet ceev.
- VGA & HDMI Ports: Ntawm lub motherboard no, muaj qhov chaw nres nkoj HDMI thiab VGA chaw nres nkoj los muab cov yeeb yaj kiab tawm rau cov hom khoom siv. Lwm yam uas koj yuav pom yog DVI.
- Audio Ports: Kev sib xyaw ua ke-tawm, microphone, thiab kab-hauv cov chaw nres nkoj muab kev nkag mus rau kev sib xyaw suab, txhais tau tias tsis tas yuav muaj daim npav suab ntawm lub khoos phis tawj tshwj xeeb no.
- PS/2 Chaw nres nkoj: Cov keyboards qub thiab nas uas tsis yog USB cov khoom siv yuav txuas rau lub computer ntawm PS / 2 chaw nres nkoj, uas tsis muaj nyob hauv daim duab saum toj no. Cov khoos phis tawj tshiab tshiab feem ntau tsis tuaj nrog PS/2 kev sib txuas.
- Serial & Parallel Ports: Tsis tas li ntawd tsis tau qhia ntawm no yog qhov chaw nres nkoj serial thiab qhov chaw sib txuas kom tso cai rau kev sib txuas rau cov tshuab luam ntawv thiab lwm yam khoom siv sab nraud. Zoo li nas thiab cov keyboards, cov khoom siv no tau hloov pauv los ntawm USB.
