Izinhlobo Computer Memory

Computer ngeke sigcine izinhlobo eziningi inkumbulo. Kukhona amacebo eziqukethe ulwazi isikhathi, ngenkathi abanye lingacushwa, futhi abanye bangase ulwazi olulondolozwe isikhathi eside. Ukugcina unaphakade esiningi idatha, ungasebenzisa hard drive, kanye akwazi ukugcina optical ngetakhiwo letehlukene. Lezi amadivayisi zangaphandle kwahambisana by inkumbulo module ukuthi plugs singene umbadlana.

Kukhona ezinye izinhlobo inkumbulo computer: ROM drive, RAM, kanzima drive, ngemoto optical kanye namadivayisi ahlukahlukene ephathekayo isitoreji.

Njengoba isibonelo omunye izinhlobo ROM - inkumbuza ukufunda kuphela, kungaholela BIOS. Lolu hlobo ezakhelwe ibhodi uhlelo, futhi isetshenziswa ngesikhathi besanda kuqala ukuqala computer. Lokhu inkumbulo iqukethe iqoqo isofthiwe eziphawuleka kakhulu ukuthi usungula uxhumano kokuqala phakathi amadivayisi ukuze uthole ulwazi input bese okukhipha. BIOS ukwakha ibhuloho phakathi microprocessor kanye idrayivu kanzima equkethe uhlelo lokusebenza le-computer. Le nqubo ibizwa ngokuthi kanye ukulayishwa.

ROM - lawa ikhompyutha inkumbulo izinhlobo ezihluke kakhulu kuzo zonke ezinye, ngoba zenzelwe ukufinyelela ngesivinini. Lolu hlobo isetshenziswa kuphela ukugcina imininingwane. Ngokubukeka ROM kuyinto chip ehlangene, ngokuvamile asikwazi ukushintshwa. Ngokungafani lolu hlobo kwabanye ukuthi kumelwe ukufinyelela ngesivinini esikhulu, futhi wokufundwayo yayo umjikelezo kufanele kube ongatheni, alinaso izingxenye ezinyakazayo, imisebenzi efana ngakho futhi baye baba kungenzeka. Lolu hlobo is zihlukaniswa yokuthi yikuphi ukwaziswa okugcinwe kwi-ke, futhi ngesikhathi lapho ikhompyutha ivuliwe ngokuphelele off.

RAM kuyinto inkumbulo kudivayisi ngesivinini, okuyinto asetshenziselwa ukugcina ulwazi ngesikhathi ukusebenza computer. Le ndlela ulwazi isitoreji kungenzeka kuphela uma i-computer ivuliwe futhi egijima. RAM inkumbulo computer ziye ngokwesiko enikeziwe amamojuli ukuthi ingafakwa isuswe noma indawo uma uthanda. Injongo yalolu hlobo ukuba sigcine idatha Lesisemkhatsini etholwe ngesikhathi ukusebenza microprocessor. Isikhathi ukufinyelela idatha kufanele kube ongatheni, ngakho amamojuli RAM embukisweni nezimfuneko ezithile.

Kukhona futhi izinhlobo inkumbulo computer evumela yokugcina ulwazi u-Adalberto isikhathi eside. Ngokwesibonelo, hard disk drive umshini senzelwe isitoreji unomphela ulwazi kanye nedatha ezingavikelekile kusulwe phakathi ukuvala shaqa. Ngokuvamile on the hard disk efakwe kusistimu yokusebenza kanye ezidingekayo software lesicelo. I hard disk drive exhunywe kwi-umbadlana, nedivayisi isitoreji sangaphandle.

Izinhlobo inkumbulo computer kanye nokuxhumana kwabo

Ngezinye izikhathi kukhona isimo uma ubona esikrinini umyalezo: ". Imemori enganele virtual" Kulokhu, kufanele uqaphele ukuthi ikhompyutha ngesikhathi msebenzi kuphela nokusebenza, kodwa inkumbulo ngokomzimba yama-computer, ngakho ngenxa yokuntula inkumbulo libhekisela endaweni yokulahla inkumbulo, usayizi okuyinto kuncike izilungiselelo ikhompyutha. Umsebenzisi kungandisa kule ncwadi, okuyinto lula kakhulu umsebenzi. Ukuze wenze lokhu, ngena ku izilungiselelo uhlelo lwakho futhi uthole into "Speed" lapho ukwenza izinguquko ezidingekayo. Kufanele ukhethe kudiski ifayela eguqulayo kanye nosayizi wefayela.

Esinye isilwane esibalulekile - memory inqolobane ikhompyutha, okuyinto wenza imisebenzi sesikhashana, exchange kolwazi phakathi processor RAM. Lolu hlobo imemori esheshayo, kubalulekile ukuqinisekisa ekusebenzeni ikhompyutha eliphezulu. Ngokwesiko, inani lememori enjalo ububanzi 128-512 amakhilobhayithi.
