Kusiyana kwa nkhosa zamphongo ddr2, ddr3, ndi ddr4
RAM ndiye chidule cha Random Access Memory. Imadziwikanso kuti "Random Access Memory", ndi mtundu wa kukumbukira kwakanthawi. Chifukwa chake, chidziwitso chimatayika nthawi yomweyo mphamvu ikazimitsidwa kapena kompyuta ikayambiranso.
RAM imagwiritsidwa ntchito kudziwa momwe mapulogalamu amagwirira ntchito, izi zikutanthauza kuchuluka kwa mapulogalamu omwe angagwiritsidwe ntchito kuyendetsa, ndichifukwa chake ogwiritsa ntchito amalangizidwa kuti apeze ndikugula mitundu yabwino kwambiri ya RAM chifukwa ndi zina mwazinthu zazikulu pakufulumizitsa kompyuta. .
Pa positiyi, tidziwa pamodzi za mitundu ya RAM ndi kusiyana pakati pawo kuti mudziwe zonse, makamaka ngati mukuganiza zosintha RAM mu kompyuta yanu.

Mitundu ya RAM
Pali mitundu iwiri ya RAM, mtundu woyamba umadziwika kuti SINGLE IN LINE MEMORY MODULE ndipo ufupikitsidwa ku “SIMM” womwe ndi mtundu wakale womwe unkagwiritsidwa ntchito kale ndi zida za 486DX2, pomwe mtundu wachiwiri umadziwika kuti DUAL IN LINE MODORY, chidule monga DIMM ndipo imagawidwa m'mitundu itatu, yomwe ndi SDRAM DDRAM ndi RDRAM.
Mtundu woyamba ndi Single Data Rate Random Access Memory, yofupikitsidwa monga "SDRAM", yomwe ndi imodzi mwa mitundu yakale kwambiri ndipo palibe ntchito yamtunduwu m'nthawi yathu ino. Mtundu uwu umasintha zambiri pa liwiro lofooka kwambiri komanso lochepa ndipo umadya mphamvu zambiri.
Mtundu wachiwiri, Double Data Rate-Synchronous DRAM, ndi chidule cha DDRAM. Mtundu uwu umagwira ntchito kwambiri kuwirikiza kawiri machitidwe a mtundu woyamba kuwonjezera pa kuwononga mphamvu zochepa ndipo uli ndi mitundu itatu yosiyana, yomwe ndi DD-RAM I - DD-RAM II - DD-RAM III yomwe imayimira DDR1 - DDR2. DDR3 kukumbukira.
Mtundu wachitatu, womwe ndi kukumbukira kwachisawawa kwa Rambus ndi "RDRAM" mwachidule "Rambus Dynamic Random Access Memory", imadziwika ndi liwiro lalikulu komanso mtengo wokwera kuposa mitundu ina yomwe yatchulidwa pamwambapa, ndipo imagwira ntchito kwambiri kugawa ndi kusamutsa deta pakati pa kukumbukira ndi purosesa kumalo oposa amodzi. Kampaniyo idayimitsa mtundu uwu chifukwa cha mtengo wake wokwera kuphatikiza kuti DDR2 ili ndi zotsatira zamphamvu komanso mtengo wotsika.
Kusiyana pakati pa nkhosa zamphongo ddr1 – ddr2 – ddr3 – ddr4
DDR1: Mtundu wakale komanso wosowa, mtundu woyamba wa ddram.
DDR2: Mtunduwu ndiwofala kwambiri ndipo umapezeka m'njira zambiri ndipo umagwiritsidwanso ntchito ngati purosesa pamakompyuta apakompyuta ndi laputopu komanso, mtundu uwu ndi wogwiritsa ntchito mphamvu ndipo uli ndi voteji mpaka 1.8 GHz.
DDR3: Mtundu uwu ndi woyenera kwambiri pa laputopu ndipo uli ndi ubwino wowonjezera liwiro la ntchito pamene umachepetsa kugwiritsa ntchito mphamvu, koma mtengo wake ndi wokwera poyerekeza ndi DDR2
Nkhaniyi yatha, ndikukuwonani, owerenga okondedwa, m'nkhani zina
