RAM - ntoni na kwaye isebenza njani?

Ngokuthenga ikhompyutha entsha, usoloko ingqalelo iimpawu zayo, ukuba ubuso bakhe kunye okulungileyo. Phakathi kwabaninzi iparameters afunekayo ukuhlangabezana ekunciphiseni iileta ezintathu - RAM. Yintoni na yaye kutheni ufuna? Yintoni na imali kangangoko ezifunekayo ukusebenza okuqhelekileyo PC? Ngayo yonke le kamva.

Inkcazo kunye nemisebenzi

RAM - Ukufikelela Memory Random yokugcina data xa ikhompyutha. Oko kukuthi, zonke iinkqubo ezisebenzayo kunye imisebenzi kwi PC yakho kule ndawo lugcinwe-time real, apho kusingathwa kamva kumqhubekekisi. Ungafumana kwakhona & igama yesibini yale isixhobo - RAM, ukuba IsiNgesi limele imemori yofikelelo oluzenzekelayo, okanye "inkumbulo kunye terminal ngokwesigqibo esicalanye." RAM kukho inani lemisebenzi ebalulekileyo, ngaphandle apho inkqubo yonke nje akunakwenzeka:

1. izibalo Storage aggregate ukuba zilungiswa yi kumqhubekekisi.
2. imiyalelo Ukugcinwa kunye nezenzo zithunyelwa ngaxesha-CPU lwenkqubo kanye ukudlalwa. Idatha sinokusulela kuphela ngqo iprosesa, kodwa inkumbulo yayo cache, nto leyo kakhulu ngokukhawuleza ngaphezu RAM memory.
3. Ukubhala kunye nokufunda imixholo yeseli

Iimpawu eminye

RAM uyakwazi ukugcina ulwazi kuphela xa PC. Ukulungiselela le njongo kuyimfuneko ukugcina yonke idatha, ngalo sisebenza kwi hard drive yakho. RAM - ntoni na? Ngamanye amazwi, le isixhobo yokugcina, ngalo imisebenzi zonke iinkqubo kunye neenkqubo. Udlula i-RAM ebekwe imijelo ulwazi olutshintshayo. imemori oluzenzekelayo-ufikelelo (RAM) - yintoni yaye kuthetha ntoni koku? Le buchwepheshe ikuvumela ukuba ukufunda nokubhala nayiphi na indawo yememori nangaliphi na ixesha.

Indlela esebenza?

wenza njani RAM? Yintoni na, wena uyazi. Yaye isebenza njani? Ngokuqinisekileyo yememori iqulethe iiseli, ngamnye kubo idilesi yayo. Phezu kwako konke oko, ibe kukho inani elilinganayo ziikhowudi Ndikulinganise ngenani ku-8 (8 amasuntswana = 1 byte). Le yunithi Ubuncinane bazo naziphi iinkcukacha. Zonke nadilesi ifom amanani lokubini (0 no 1) ngokwalo kwakunye data. Iiseli ekuhlaleni, ilifa iidilesi ezilandelelanayo. Uninzi imiyalelo zenziwa usebenzisa i "igama", iindawo inkumbulo, eliquka bytes 4 okanye 8.

ngeentlobo

Ukuhlelwa jikelele yahlula isixhobo ezimbini iintlobo memory: SRAM (emile) kunye DRAM (onamandla). Eyokuqala esetyenziswa efihlakeleyo memory of the CPU idlala indima kwinkumbulo yekhomputha yesibini. Nayiphi iquka kusungula SRAM ukuba banokuba kumazwe ezimbini: "kwi" yaye "off". Ziquka yinkqubo entsonkothileyo yokwakha a chain zeteknoloji, ngenxa apho zithatha isithuba esininzi. Ixabiso ifowuni iya kuba kakhulu ngaphezulu kwe DRAM, apho akukho ezibangela, ngenxa apho RAM ifunyenwe compact kodwa transistor elinye capacitor omnye (umz - RAM DDR2). Imali ngokufanelekileyo ixesha layo esebenzayo zomyalelo-4 GB, ukuba iqonga computer ilungiselelwe imidlalo, ngoko kuyacetyiswa ukuba ukwandisa eli nani ngu 2 umphinda-. Namhlanje siye saqonda ukuba RAM - ntoni na kwaye isebenza njani. Ngoku ke umfundi umgaqo esisiseko ukusebenza kwale divayisi.
