Imemori ye-ROM uhlobo lwesitoreji sokufundwa kuphela esinamakhompyutha nemishini ye-elektroniki. Iyatholakala kodwa ayiguquki. Funda kabanzi ngalesi sihloko ngokufunda i-athikili elandelayo.
Imemori ye-ROM
Uma ukhuluma ngememori ye-ROM, kukhulunywa ngohlobo lwesitoreji esizosetshenziswa ekufundeni imisebenzi. Ibizwa ngamagama ngesiNgisi "Imemori Yokufunda Kuphela", "imemori yokufunda eyodwa". Kutholakala kuwo wonke ama-computer nakwizinto zobuchwepheshe ezimakethe namuhla.
Le memori ye-ROM inesimo sokuthi ingatholwa kuphela uma kwenzeka ilahlekile kepha idatha yayo ayikwazi ukuguqulwa. Yenzelwe izinqubo zokufunda kuphela. Inokusebenza okuzimele ngisho nasekuhambeni kwamandla. Lokhu kuyivumela ukuthi ingabumbeki noma iguquke.
Ifakwa kwimemori noma ekhadini lezinto zokusebenza ngesikhathi zenziwa. Kungaba wuhlobo oluyisisekelo noma oluyinhloko. Ukusebenza kwayo kuhamba kancane kune-RAM kadadewabo. Okuqukethwe ngokuvamile kufakwa ku-RAM ukuze kusebenze ngokushesha. ngaleyo ndlela-ke siyazi i-ROM yenzelwe ini
Ama-ROM eza ngezinhlobo ezahlukahlukene. Izinhlobo ezaziwa kakhulu yizinhlobo ze-EPROM ne-EEPROM. Banamandla wokuthi bangahlelwa futhi bahlelwe kabusha kaningana. Ochwepheshe ngokuvamile bazama ukungazisebenzisi, ngoba ukusetha kabusha kwazo kuhamba kancane kakhulu.
Zenzeleni
Ake sibone ngezansi Iyini i-ROM? Lezi zinkumbulo ngokuvamile zisetshenziselwa ukugcinwa kwesoftware. Zisetshenziselwa ukufaka izinhlelo zokuqalisa futhi zikuvumela ukuthi uphathe ukusebenza okuyisisekelo kwemishini. Njenge-BIOS ne-Set Up phakathi kwabanye. Ngaphambilini, izinkumbulo ze-ROM bezihlelwe kuphela ukugcina izinhlelo zokusebenza. Umqondo bekuwukuvikela abasebenzisi ekuguquleni okuqukethwe kwayo.
Okunye Isici se-ROM ukuthi isetshenziselwa ukugcina idatha engadingi ukuguqulwa empilweni elusizo yekhompyutha. Le datha ingaba ukusebenza kwezibalo okunengqondo, amatafula wokubheka, noma eminye imisebenzi yohlobo lobuchwepheshe. Abahleli abaningi basebenzisa izikhala zokugcina imemori ze-ROM ukugcina imininingwane ezimele.
Izinhlobo zememori ye-ROM
Emakethe kunezinhlobo eziningana zememori yeROM lapho intengo yayo iyehluka kuye ngokusebenza kwayo namandla ayo. Noma kunjalo, amakhompyutha amaningi awadingi ukushintsha le nkumbulo njalo. Ifundelwa kuphela futhi ayonakaliseki njalo. Kepha ake sibone okubaluleke kakhulu
- I-EPROM, iyinkumbulo yokuthi izinhlamvu zayo zinikeza incazelo ye- "Imemori Yokufunda Efundwayo Engahlehleleka NgeSpanishi" ngeSpanishi "Ingasetshenziswa futhi Ihlelwe Imemori Yokufunda Kuphela". Kuyinkumbulo yohlobo lwe-EEPROM, engasuswa lapho ivezwa ukukhanya kwe-ultraviolet noma uma ithola amandla kagesi aphezulu. Ikuvumela ukuthi usule idatha equkethwe futhi usebenzise okunye ukufaka esikhundleni
- I-PROM imele "Imemori efundwayo yokufunda kuphela" noma "Imemori yokufunda ehleliwe kuphela". Lolu hlobo lwememori lufakwa ekhompyutheni futhi lungahlelwa kanye kuphela. Ngoba ine-fuse encane engashintshwa.
- I-EEPROM, imele ukuthi "Imemori efundeka kuphela ehlelwa ngogesi" ngeSpanishi. Imemori efundeka kuphela ngogesi futhi ehlelwayo. Lokho wukuthi, le nkumbulo ayidingi imisebe ye-ultraviolet ukusula okuqukethwe kwayo, ingacushwa ngaphakathi kwesekethe uqobo. Ukufinyelela izingcezwana ngawodwana.
Umehluko nge-RAM
Phakathi kwe Izinkumbulo ze-ROM ne-RAM kukhona umehluko obalulekile. Esokuqala isivinini sokudlulisa. Lapho ukuhamba kolwazi ku-RAM kungaguquguquki ngokwengeziwe. Ngakolunye uhlangothi, i-RAM, ngokungafani neMemori ROM, iyaqoshwa kuzo zonke izingxenye zayo, noma ivumela imisebenzi ehlukahlukene yokugcina kanye nokusula ukuthi yenziwe.
Izinhlelo zokuqalisa ziya kule database okwesikhashana, zilahleke lapho ikhompyutha icishiwe noma uhlelo luqaliswa kabusha. Imemori ye-RAM ihlanzekile ngokuphelele futhi ilungele ukusetshenziswa futhi. Ngenkathi i-RAM igcina okuqukethwe kwayo. Ukusebenza kwememori ye-RAM kuphakeme kune-ROM
Ngezinhloso zokusebenza kahle kuyashesha, kushibhile futhi kuqinile. Ngakho-ke onjiniyela abaningi bezinhlelo bakhetha ukukusebenzisa kakhulu kune-ROM. Akusho ukuthi imemori ye-ROM ekusebenzeni kwayo konke inezinkinga. Ukuthi insizakalo eyinikezayo yehlukile kunaleyo enikezwe yi-RAM.
Enye inzuzo ye-ROM isikhala esandisiwe kwimemori yangaphakathi. Ngokungabi nemininingwane eminingi ongayicubungula njengezicelo nezinhlelo eziqhubekayo. Ukusebenza kukhuphuke kakhulu. Iyanciphisa ukusetshenziswa kwebhethri, ivumela ukunweba impilo yemishini.
