Cov txheej txheem defragmentation feem ntau yog hu ua qhov xaj ntawm cov ntsiab lus ntawm pawg kom nce qhov ceev ntawm kev nkag mus rau cov ntaub ntawv tsim nyog thiab txhim kho kev ua haujlwm ntawm lub computer.
Txuag cov ntaub ntawv ntawm lub hard disk yog encrypted. Qhov ntsuas me tshaj ntawm cov ntaub ntawv khaws cia yog me ntsis nrog tus nqi ntawm 1 lossis 0. Ib qho byte yog sib npaug rau 8 cov lus nyob rau hauv ntau cov kev sib txuas, i.e. 256 tus cim. Tus lej sib xyaw ua ke yog Kilo-, Mega-, Giga- thiab Terabytes. Kev sib xyaw ntawm qee qhov ntawm bytes, tsim los khaws cov ntaub ntawv ntawm qee cov ntaub ntawv, hu ua pawg. Qhov ntau thiab tsawg ntawm cov pawg tsis tso cai rau khaws tag nrho cov ntaub ntawv xaiv hauv ib pawg, yog li cov ntaub ntawv tau muab faib ua tawg (cov txheej txheem tawg yuav muaj nyob). Kev khiav hauj lwm ntawm lub khoos phis tawm muab cov naj npawb uas yuav tsum muaj los sau tag nrho cov ntaub ntawv tsim nyog, tab sis tsis lav txog qhov ua haujlwm ntawm nws cov khoom cia. Tsis tas li ntawd, nyob rau hauv tus txheej txheem ntawm kev ua haujlwm, qee cov ntaub ntawv yog kho, ntxiv thiab muab tua. Tag nrho cov no ua rau cov ntaub ntawv ntxaws ntxig ntxiv thiab nce qib ntawm kev tawg. Qhov ntaub ntawv tsis muaj kev cuam tshuam rau nws txoj haujlwm, tab sis tuaj yeem ua rau lub computer ploj zuj zus thiab ua rau lub luag haujlwm ntawm cov programs nruab rau nws. ntawm lub hard disk tso cai rau koj los rov qab ua ntu zus ntawm kev tso chaw ntawm cov ntaub ntawv ntawm daim disk thiab muab cov sib xyaws tsis tiav rau Microsoft Windows muaj cov cuab yeej tiv thaiv uas tso cai rau koj los ua cov txheej txheem no yam tsis tas yuav tsum muaj cov software thib peb. Txhawm rau ua txoj haujlwm, xaiv lub disk kom raug defragmented thiab hu nws cov ntawv qhia zaub mov los ntawm txhaj cov khawm xis. Koj yuav tsum tau hais kom meej cov khoom "Cov Khoom" thiab mus rau "Kev pabcuam" tab ntawm cov lus qhib lub thawv qhib, qhov chaw koj xaiv qhov "Ua defragmentation". Nws yuav tsum nco ntsoov tias defragmentation pom zoo thaum nquag ntxiv thiab tshem tawm cov ntaub ntawv thiab cov ntawv, txhim kho thiab nruab cov ntawv thov tshiab thiab siv cov txheej txheem los hloov kho koj cov kev ua haujlwm.
