Yog tias koj lub khoos phis tawm ua haujlwm ib qho ntawm cov khoos phis tawm ntawm Windows, tom qab ntawd hauv cov hauv paus ntawm qhov disk uas qhov system tau teeb tsa muaj cov ntawv uas txiav txim siab loj hu ua pagefile.sys. Nws yog hu ua "hloov cov ntaub ntawv" lossis cov ntawv thov sib pauv, thiab lub operating system xav tau nws, feem ntau yog ua haujlwm nrog RAM.
Cia hais tias koj ua haujlwm ntev thiab nyuaj hauv Lo Lus lossis Photoshop rau ntawm daim ntawv, thiab tom qab ntawd nws yog lub sijhawm rau ob peb kaum feeb los cuam tshuam ntawm txoj haujlwm nyuaj thiab so. Thaum tsis muaj tus thawj coj nyob ze, txoj hauv kev tsim nyog tshaj plaws yog txhaws ob peb lub kaum os monsters hauv kev ua yeeb yaj kiab video. Thaum koj khiav nws yam tsis tau kaw cov ntaub ntawv uas koj tau ua haujlwm, lub operating system yuav tau saib xyuas kom tsis pub dhau RAM rau lub luag haujlwm tshiab. Txhawm rau ua qhov no, nws yuav txav qee thaj chaw (nplooj ntawv) rau cov ntawv paging, thiab thaum koj rov ua haujlwm dua, OS yuav ua cov txheej txheem rov qab - nws nyeem cov khoom tsim nyog los ntawm cov ntawv sib dhos rau hauv RAM. Nws ua raws los ntawm cov txheej txheem no ntawm kev siv lub cim xeeb virtual uas qhov ntau dua "RAM" tau nruab rau hauv lub khoos phis tawm, cov ntaub ntawv paging tsawg dua yog siv los ntawm cov kab ke thiab lub tshuab ua haujlwm nrawm dua. Qhov no yog vim hais tias qhov nrawm ntawm kev sau ntawv thiab nyeem ntawv rau lub hard disk yog qhov qis dua rau kev ua haujlwm zoo sib xws nrog RAM hauv microchips.
Thaum cov operating system tshiab tau nruab rau hauv lub khoos phis tawm, nws teeb tsa qhov loj me ntawm cov ntawv pabcuam no mus rau qhov loj ntawm cov RAM uas twb muaj lawm los ntawm lub neej ntawd. Txawm li cas los xij, yog tias koj ntseeg siab tias koj lub khoos phis tawm muaj RAM ntau txaus rau koj txoj haujlwm, koj tuaj yeem nce qhov chaw me me ntawm koj lub hard disk los ntawm kev txo qhov me me ntawm pagefile.sys cov ntaub ntawv los ntawm ob peb gigabytes. Thiab yog tias muaj qhov tsis pom tseeb ntawm RAM, koj yuav tsum ua qhov tsis sib xws - nce qhov loj me ntawm daim ntawv sib puav. Qhov no tsis tau ua "ntawm tus kheej" - cov lus sib piv tau muab los ntawm lub chaw tsim khoom lag luam Windows thiab muaj nyob hauv ib qho ntawm "Cov Tswj" rau ib tus neeg siv OS nrog cov cai tswj hwm. Cov theem ntawm cov kauj ruam rau cov haujlwm no tau piav qhia nyob rau hauv Microsoft lub vev xaib - qhov txuas rau nplooj ntawv sib txuas ntawm cov lus qhia rau Windows 7 tau muab hauv qab no.
