Lub khoos phis tawm niaj hnub no yog cov twj siv nyuaj tshaj plaws uas tau koom nrog qhov ua tau zoo ntawm kev ua tiav ntawm science thiab kev vam meej. Ib qho tseem ceeb tshaj plaws ntawm ib lub khoos phis tawm yog nws lub RAM.
Lub khoos phis tawm muaj ob hom kev nco: ruaj khov thiab ua haujlwm. Qhov tsis tu ncua yog tus cwj pwm los ntawm qhov tseeb tias tag nrho cov ntaub ntawv sau cia rau ntawm ib qho chaw cia khoom nruab nrab - lub hard disk. Thaum koj kaw koj lub computer, tag nrho cov ntaub ntawv khaws tseg ntawm koj lub hard drive tseem nyob hauv. Qhov xwm txheej no txawv nrog RAM - cov ntaub ntawv khaws cia hauv nws tsuas yog thaum lub computer khiav ua haujlwm. Vim li cas thiaj yuav tsum tau RAM? Ua ntej txhua yam, hom ntawm lub cim xeeb yog nrawm heev, nws yuav siv cov kev ua haujlwm siv sijhawm tsawg dua nws nkag mus thaum nws nkag mus hauv lub hard disk. Tsis tas li ntawd, nws nyob hauv lub RAM uas khiav cov haujlwm tau txais kev cawm. Qhib Tus Thawj Tuav Haujlwm (Ctrl + alt="Duab" + Del) thiab saib rau ntu "Lub Cim" - koj yuav pom tus nqi ntawm lub RAM tso los ntawm cov haujlwm tam sim no. Raws li cov kev zov me nyuam khiav, qhov lawv nco tau ntau dua tuaj yeem hloov pauv; RAM ntau dua koj lub computer muaj, nws yuav ua tau zoo dua. Muaj tseeb, 32-ntsis version ntawm lub Windows XP operating system tsis txhawb nqa ntau dua peb gigabytes ntawm lub cim xeeb. Nws cov 64-ntsis version txhawb txog li 128 gigabytes ntawm RAM, tab sis hauv kev muaj tiag, qhov no, txhua yam nyob ntawm lub peev xwm ntawm cov niam tsev. Lub Windows 7 ua haujlwm hauv 32-ntsis version txhawb 4 gigabytes ntawm RAM. Hauv nws cov 64-ntsis version, qhov loj me ntawm qhov kev txhawb nqa RAM yog nyob ntawm OS version: hauv thawj zaug - Lub hauv paus pib thiab Lub Tsev Hwm - nws yog 8 thiab 16 gigabytes, ntsig txog, Professional, Enterprise thiab Ultimate version txhawb txog 192 gigabytes. Tau kawg, ntawm no qhov tseeb lub cim xeeb txhawb kev muaj peev xwm feem ntau nyob ntawm lub peev xwm ntawm cov niam. Hom RAM kuj tseem ceeb: SIMM, DIMM, DDR, DDR2, DDR3. Thawj ob yog twb dhau heev lawm, yog li nws nyuaj rau hla lawv. Tseem tshuav peb hom ntxiv raug teeb tsa rau feem ntau ntawm cov khoos phis tawj niaj hnub no. Qhov ntau ntawm cov cim xeeb nco siv yog, nws ua haujlwm nrawm dua. Nco microcircuits tau sib sau ua ke rau hauv cov qauv, lawv tseem hu ua strips. Modules tau ntsia rau hauv lawv cov ntaub ntawv tsim ntawm qhov chaw ntawm motherboard.
