Lub khoos phis tawj ntiag tug ntawm txhua tus neeg siv muaj lub cim xeeb sab nraud thiab sab hauv, tab sis tsis yog txhua tus paub tias nws yog dab tsi thiab nws ua haujlwm dab tsi.
Lub cim xeeb sab hauv ntawm lub khoos phis tawm ntawm tus kheej yog qhov tshwj xeeb cia khoom siv uas ua haujlwm ncaj qha nrog cov processor. Qhov kev nco no yog npaj rau khaws cia thiab ua ntau yam software, nrog rau nws cov ntaub ntawv. Sab hauv lub cim xeeb muaj qhov tsawg tsawg thiab muab faib ua ntu tsis nco qab, lub cim xeeb nco, thiab RAM.
Random nkag nco
Tej zaum, yog dab tsi random nkag tau nco, txhua tus neeg siv ntawm lub khoos phis tawm ntawm tus kheej yuav tsum paub. RAM yog lub kaw lus ceev tshaj plaws hauv lub khoos phis tawj, tab sis txhua zaus muab tua / kaw, lub cim xeeb no pib rov rau xoom. RAM yog npaj rau kev cia ib ntus, kis thiab xa cov ntaub ntawv. Nws yuav tsum raug sau tseg tias niaj hnub no ntau hom RAM raug faib, cov no yog: DDR SDRAM (lossis DDR I), DDR 2 SDRAM thiab DDR 3 SDRAM. Thawj hom ntawm kev nkag mus rau lub cim xeeb tsis pom qhov twg niaj hnub no, tsuas yog cov khoos phis tawj qub, vim nws tsis yog cov thev naus laus zis. Feem ntau tam sim no koj tuaj yeem nrhiav DDR 3 SDRAM RAM. Nws yog hom neeg hloov pauv tau rau DDR 2 SDRAM. Xws li RAM tau dhau los ua neeg nyiam vim qhov tseeb tias nws siv ntau lub sijhawm tsawg dua lub zog tsawg dua li DDR 2 SDRAM (los ntawm kwv yees li 40%).
Cache cim xeeb
Raws li rau lub cim xeeb cache, nws yog lub tshuab ceev ceev tshaj plaws uas siv hauv kev sib pauv thiab ua cov ntaub ntawv ncaj qha nruab nrab ntawm cov processor thiab RAM. Feem ntau, cov cim xeeb feem ntau nyob ntawm lub microprocessor nti, thaum uas tseem nyob sab nraud. Tus neeg siv yuav tsis tuaj yeem nkag mus rau hauv lub cim xeeb nco hauv txhua txoj kev, vim nws tus kheej yog programmatically mus cuag. Txhawm rau kom tus neeg siv nkag mus rau lub cache ncaj qha, nws yuav tsum siv lub khoos phis tawm ntawm lub khoos phis tawm.
Nyeem nkaus xwb
Tus nyeem ntawv nco tsuas ntaus ntawv tuaj yeem siv tau los ntawm tus neeg siv tsuas yog rau kev nyeem cov ntaub ntawv. Ua ntej tshaj plaws, ib qhov kev pab cuam tau sau rau hauv ROM los tswj kev ua haujlwm ntawm tus txheej txheem nws tus kheej hauv lub computer. Qhov no yog qhov twg txhua tus tsav tsheb los tswj cov khoom siv hluav taws xob (rau saib, tshuab luam ntawv, ntaus ntawv, thiab lwm yam), thiab cov kev pab cuam rau kev pib thiab nres lub khoos phis tawm, cov khoom siv sim thiab qhov tseem ceeb tshaj plaws ntawm lub cim xeeb mus tas li - BIOS module Cov.
