PC System [hardware]

Haaa...bape ramai pggune computer kt Malaysia ni yg btol2 tau pasal computer system n camne dia berfungsi.aleheii...aku rase xsmpai 20% pon la..Sbgai pggune pc yg bijak pe slhnye la kite ambik tau skit camne PC kite ni berfungsi...at least kalo ttbe rosak ke...ttbe slow ke...ttbe mggile computer kite 2...xdela kite mengamuk xtntu pasal.oraittt...zassss...

Basic hardware system kt PC kite consist of motherboard, power supply, processor, Random access memory (RAM), hard drive, sound card and video card. Yg len2 2 korg bole tmbah ikut application yg korg nk cam TV card (utk tgk tv), 3D card (utk men game yg dasyat2 gmbar dia) or disc drive (utk main CD or DVD).


Mother Board

Raja sgle board dlm PC.smua hardware2 korg mst kene attact to this board. Kalo nk wat analogy la..motherboard ni macam saraf tunjang kat dlm bdn kite ni.sbb saraf tunang la yg mghubungkan sgla hardware badan kite ( cam mata, telinga, tangan bla blaa..) dgn otak dan sebaliknye. Motherboard dilengkapi dgn system Basic input Output System (BIOS) chipset utk kawal setup motherboard. Haaaa...ape lak BIOS ni.cam slalu dgr kan...tp tau ke??:P hurmmm...BIOS ni sbnrnye system yg kawal PC korg dr stat on smpai la Operating System ( OS ni cam Window, Mac Linux smua 2 la) take over. BIOS ni akn pastikan smua hardware korg function as normal dulu..n bile smua da ok baru la dia akn upload Operating System into the RAM. Haaa..pening da..RAM ni utk ape lak kan...sabo2...nnt cite...

Power Supply

Power supply ni bnde yg mmberi tenage kt PC kite la. dr name da bole agk kan. Tp apekah sbnrnye function2 dia. nape kite xpkai direct current trus je kan dr umah kite 2.nape kene lalu power supply??haaa...power supply ni 1stly dia akan convert AC current to DC current. ade 3 typical voltage yg biase utk power supply iaitu 3.3V, 5V and 12V. 12V ni biase nye kalo korg nk pasang2 kipas extra kene ar pkai 12V. kalo x..pkai 3.3V or 5V da ckp da. Power supply jugak ade system on and off. korg slalu men picit je kan nk bukak PC 2.sbnrny..bile korg picit 2...5V signal akn dihantar ke power supply utk bgtau power supply supaya mula bg power kt whole system. Cam 2 gk ngn shut down..bile kite click shut down another 5volt signal akn dihntar maka power supply pon tutup la. PC dulu2 xde beb..nk off bile da click shutdown 2 kene tggu.bile da tulis "it's now safe to turn off ur PC" haaa...kene off manually power supply kite. Cam suiz lampu bilik je beb...

Processor or Central Processing Unit (CPU)

Haaa...slalu ar budak2 ni dok sebut CPU 2...sbnrny CPU 2 processor. yg besau 2 bukan CPU...2 casing je. orait...CPU ni bole dianalogikan cam otak la.lg bijak otak kite...lg cepat kite berfikir. kalo PC...lg mahal processor kite lg cpt la maklumat diprocess. 3 ciri2 pnting utk processor ialah clock speed (running speed), FSB (data transfer speed antara CPU ngn RAM) n L2 Cache speed (frequent use memory...xyh la lalu RAM spye laju skit).

Random Access Memory (RAM)

RAM ni gune nye utk simpan temporary memory (istilah omputih vapor memory) yg mane memory ni hanye kekal slagi PC on.Bile PC off je...automatic smua memory 2 hilang.Lg besar RAM kite ni lg byk la memory kite leh simpan dlm satu mase. RAM ni adela kaitan dgn kalajuan PC dimana kite bole analogikn dia cam highway yg mghubungkan CPU dgn any input and output hardware. Ha...ingt time explanation CPU td..hanya L2 Cache memory je yg xlalu RAM sbb mmory ni slalu gune.So direct simpan kt dlm processor. kalo RAM kite tggi lg byk la kite leh wat keje 1 mase dgn kelajuan yg still bgus. Sbb highway kite besar kan...byk kete lalu pon xjam.haaa...kalo highway kite kecik...2 yg bole wat PC jd hang 2.kkdg ade virus yg running kan certain program 2 byk2 mmbuatkan gune byk memory. So PC senang hang...xyh la ngamok2 kalo ttbe PC ske hang ye...


Demm..da pnt menulis...nnt sambung lg...chaloss~~
