Inkumbulo enesiqhamo ye computer kunye nendlela ukwandisa

imemori Virtual i iteknoloji ikhethekileyo apho ulawulo memory lwezixokelelwano beelwimi zabantu zekhompyutha asebenzisa iinkqubo yokusebenza nemiba ngemiba yezemfundo. Umongo obu bugcisa kuxhomekeke kwinto yokuba inkqubo nganye ukuqinisekisa ukusebenza kwayo inxenye sixhobo, libhekisela kwimemori elipheleleyo computer kwindawo eyahlukileyo. Ethetha oku ngendlela ethile siboniswe umnqongo ebonakalayo ukuba unikeza le inkumbulo. Ukunyuka kwinkumbulo ukusebenza, ihlelwe ngale ndlela, ifunyanwa yi kukuba isithuba inkumbulo efunekayo igcinelwe kwinkqubo nganye isebenza. Ukongeza, i-virtual memory ye computer kuvumela umsebenzisi ukuba ukwandisa ngumthamo opheleleyo, ukufikelela amanani ukuba idlule abo eziqulethwe izixhobo eziphathekayo. Oku kuqinisekiswa afakwe iteknoloji izibonelelo ezingasetyenziswanga kwi yogcino.

Ukuvela obu bugcisa inxulumene phakathi kwinkulungwane yokugqibela. Ngaphambi koku, inqanaba ezimbini memory ezisetyenziswa izixhobo computing - eziziprayimari nezizisekondari. Ukuvela inkumbulo enesiqhamo sele masikhokelwe imfuneko ukufumana imo ukulawula elula kuyo.

Xa usebenzisa inkumbulo enesiqhamo nekhompyutha lula kakhulu inkqubo iprogram kuba akubikho imfuneko ukugcina ulawulo rhoqo phezu ubungakanani memory kwaye simahla okanye ayisasaze phakathi kweenkqubo ukubaleka. Kuba phantse zonke izicelo ezisebenza phantsi oku inikeza unikezelo kuyo yonke isithuba idilesi, nokuba umthamo yayo phezu izixhobo eziphathekayo ubalwe.

Ngengqiqo ezininzi jikelele, lo inkumbulo enesiqhamo nekhompyutha wenza le misebenzi ilandelayo:

- kube lula yaye rationalizes nokulungisa izicelo inkumbulo aphilileyo;

- libonelela ulawulo memory kakuhle - RAM, by Ukukhetha kunye nokugcinwa izicelo ezininzi ezithandwayo kunye asetyenziswa rhoqo;

- babe iinkqubo computing abazilawulayo ngendlela yokuba inkqubo nganye kuphunyezwa ngokungathi yonke ikhompyutha bukwazi.

Xa iikhompyutha mihla ukudala iteknoloji inkumbulo enesiqhamo ixhaswa nangeendleko kwenkxaso yentsimbi, ngaphandle kokuba imisebenzi eyodwa, ezifuna ukulungiswa mode nokusebenza ngesantya esiphezulu kakhulu. Ngokuqhelekileyo, ezi zixhobo angenzelwanga loo ukusetyenziswa abaninzi, kodwa ngenxa yabo multifunktsional sincinci kakhulu.

Ithatyathwa obu bugcisa kuphunyezwa ngeendlela ezimbini eziphambili amalungiselelo.

Upeyijo kubandakanya lidala kwimemori amaphepha enesandi, njengoko umgaqo - 4096 bytes. Ngaphakathi, iqulathe bobungakanani befayile, nto leyo coded ulwazi malunga serial number (inombolo page) kunye nokususwa yayo. I-CPU computer uguqula inani iphepha kwi dilesi ahambelanayo. Iprosesa uguqula inani iphepha virtual kwidilesi olungqamelanayo kwi ngecebo elibonakalayo. Le yokusebenza nkqubo ngokwabo i "mkhondo" ukusetyenziswa kwale inkumbulo, kunye nolawulo kulo, kuxhomekeke ukuba okanye hayi uxakekile ngayo.

Umbutho yeengcandelo isekelwe kwinto yokuba inkumbulo enesiqhamo iyonke computer yahlulwe ezithile - ziqwempu apho inkqubo yokusebenza kwaye inikeza amalungelo ukufikelela kwinkqubo nganye. Inkqubo ukujongana kule ndlela phantse efanayo naleyo isetyenziselwa iphepha-mode, kodwa lonikezelo kwicandelo kukuqhekeka kwenzeka, nto leyo echaphazela ngokungalunganga isantya PC. Soyise ezo ukuphazamiseka kunokuba ngeendlela ezimbini: mhlawumbi ukunyusa ubungakanani imemori esetyenzisiweyo okanye ezamahala, ngokucoca ngayo ze data ezingeyomfuneko. Ukuze ufunde indlela ukukhulula inkumbulo enesiqhamo, nawuphi na umsebenzisi linokubhekisela Reference kwiSebe indlela yokusebenza obufakwe kwikhompyutha yakho kwaye kukho le nkqubo elula iinkcukacha epeyintwe.

Ukwandisa inani of inkumbulo enesiqhamo ngendlela eyiyo kungenziwa ngeendlela ezimbini eziphambili - by zokwenza nyulu, njengoko kuchaziwe apha ngasentla, okanye ukwandisa umthamo wayo ngokufaka izixhobo ezitsha. Zininzi iinkqubo eziya kukuxelela indlela ukwandisa isixa inkumbulo enesiqhamo, kunye nomgangatho uncedo yokuyenza ngokwakho.
