Imemori yeROM luhlobo lokugcinwa kokufundwa kuphela kweekhompyuter kunye nezixhobo ze-elektroniki. Iyafumaneka kodwa ayinakuguqulwa. Funda ngakumbi malunga nesi sihloko ngokufunda inqaku elilandelayo.
Imemori yeROM
Xa uthetha ngememori yeROM, kukhankanywa uhlobo lokugcina oluzakusetyenziswa kwimisebenzi yokufunda. Ibizwa sisifinyezo ngesiNgesi "Imemori yokufunda-kuphela", "inkumbulo yokufunda enye". Itholakala kuzo zonke iikhomputha kunye nezixhobo zombane kwiimarike namhlanje.
Le memori yeROM inemeko yokuba inokubuyiselwa kuphela kwimeko yelahleko kodwa idatha yayo ayinakuguqulwa. Yenzelwe iinkqubo zokufunda kuphela. Inomsebenzi ozimeleyo kunye nokuhamba kwamandla. Oku kuyivumela ukuba ingabumbeki okanye iguqulwe.
Ifakwa kwimemori okanye kwikhadi lezixhobo ngexesha lokwenziwa kwazo. Inokuba yeyodidi olusisiseko okanye oluphambili. Ukusebenza kwayo kuhamba kancinci kunodadewabo we-RAM. Umxholo ngokubanzi uqatyelwa kwi-RAM ukuze usebenze ngokukhawuleza. Ngale ndlela ke siyayazi Yintoni iROM
IiROM ziza kwiinguqulelo ezahlukeneyo. Ezona zaziwayo ziimodeli ze-EPROM kunye ne-EEPROM. Banesakhono sokuba banokucwangciswa kwaye baphinde benziwe ngokutsha amaxesha amaninzi. Iingcali ngokubanzi zizama ukungazisebenzisi, kuba ukuseta kwakhona kuhamba kancinci.
Zenzelwe ntoni
Masibone ngezantsi Yintoni imemori yeROM. Ezi nkumbulo zisetyenziselwa ukugcinwa kwesoftware. Zisetyenziselwa ukufaka iinkqubo zokuqalisa kwaye zikuvumela ukuba ulawule ukusebenza kwesiseko sezixhobo. Njenge-BIOS kunye nokuseta phakathi kwabanye. Ngaphambili, iinkumbulo zeROM zazilungiselelwe ukugcina iinkqubo zokusebenza kuphela. Injongo yayikukuthintela abasebenzisi ekutshintsheni umxholo wayo.
Okunye Umsebenzi weROM kukuba ikwasetyenziselwa ukugcina idatha engadingi kuguqulwa kubomi obuluncedo bekhompyuter. Le datha inokuba yimisebenzi esebenzayo yezibalo, iitafile zokujonga phezulu, okanye olunye uhlobo lohlobo lobuchwephesha. Iinkqubo ezininzi zisebenzisa indawo yokugcina iROM ukugcina ulwazi oluzimeleyo.
Iindidi zememori zeROM
Kwimarike kukho iintlobo ezahlukeneyo zememori yeROM apho ixabiso lalo liyahluka ngokuxhomekeka kubuchule bayo kunye namandla. Nangona kunjalo, uninzi lweekhompyuter azidingi kuyitshintsha le nkumbulo rhoqo. Ifundwa kuphela kwaye ayonakalisi rhoqo. Kodwa masibone eyona ibalulekileyo
- I-EPROM, sisikhumbuzo sokuba oonobumba bayo banika intsingiselo "yememori enokufundeka enokucwangciswa-kuphela" ngesiSpanish "enokuCinywa kunye nokuCwangciswa kwememori yokufunda kuphela". Inkumbulo yohlobo lwe-EEPROM, enokucinywa xa ityhilelwe kukukhanya kwe-ultraviolet okanye ukuba ifumana amandla ombane aphezulu. Ikuvumela ukuba ucime idatha equlathiweyo kwaye usebenzise enye
- I-PROM imele "iMemori eFundiweyo yokuFunda kuphela" okanye "iMemori eFundwayo yokuFunda kuphela". Olu hlobo lweenkumbulo ludityanisiwe kwaye lunokucwangciswa kube kanye. Ngenxa yokuba ine-fuse encinci engenakutshintshwa.
- I-EEPROM, imele "iMemori eFundwayo yokuFunda eFunyanwayo enokuCwangciswa ngogesi" ngesiSpanish. Oko kukuthi, le nkumbulo ayifuni imitha ye-ultraviolet ukucima umxholo wayo, inokucwangciswa ngaphakathi kwisekethe ngokwayo. Ukufikelela kwiibhithi ngokukodwa.
Umahluko nge-RAM
Phakathi Iinkumbulo zeROM neze-RAM kukho umahluko obalulekileyo. Eyokuqala sisantya sokuhambisa. Apho ukuhamba kolwazi kwi-RAM kuhlala kuhleli. Kwelinye icala, inkumbulo ye-RAM, ngokungafaniyo neMemori yeROM, iyarekhodwa kuwo onke amalungu, okanye ivumela imisebenzi eyahlukeneyo yokugcina kunye nokucima.
Iinkqubo zokubaleka ziya kolu luhlu okwethutyana, ukulahleka xa ikhompyuter icinyiwe okanye inkqubo iqalile kwakhona. Imemori ye-RAM icocekile kwaye ilungele ukusetyenziswa kwakhona. Ngelixa i-RAM igcina umxholo wayo. Ukusebenza kwememori ye-RAM kuphezulu kuneROM
Ukulungiselela ukusebenza ngokukuko kuyakhawuleza, kutshiphu kwaye kuzinzile. Uninzi lweenkqubo zeenjineli zikhetha ukuyisebenzisa ngakumbi kuneROM. Oko akuthethi ukuba imemori ye-ROM ekusebenzeni kwayo konke ineziphene. Yinkonzo ebonelelweyo kuphela eyahlukileyo kule ibonelelwe yi-RAM.
Enye inzuzo yeROM yindawo eyandisiweyo kwimemori yangaphakathi. Ngokungabinalo ulwazi oluninzi lokuqhubekeka njengezicelo kunye neenkqubo ezisebenzayo. Ukusebenza kunyuke kakhulu. Iyanciphisa ukusetyenziswa kwebhetri, ivumela ukwandisa ubomi besixhobo.
