Umehluko ezinqameni ddr2, ddr3, kanye ddr4
I-RAM isifinyezo se-Random Access Memory. Eyaziwa nangokuthi "Inkumbulo Yokufinyelela Okungahleliwe", iwuhlobo lwenkumbulo yesikhashana. Ngakho-ke, ulwazi lulahleka ngokushesha lapho amandla ecishiwe noma lapho ikhompuyutha iqalwa kabusha.
I-RAM isetshenziselwa ukunquma ukusebenza kwesofthiwe, lokhu kusho inani lesofthiwe engasetshenziswa ukusebenza, yingakho abasebenzisi belulekwa ukuthi bathole futhi bathenge izinhlobo ezingcono kakhulu ze-RAM ngoba ziphakathi kwezinto eziyinhloko ekusheshiseni ikhompuyutha. .
Phakathi nalokhu okuthunyelwe, sizokwazi ndawonye mayelana nezinhlobo ze-RAM kanye nomehluko phakathi kwazo ukuze wazi yonke into, ikakhulukazi uma ucabanga ukushintsha i-RAM kukhompyutha yakho.

Izinhlobo ze-RAM
Kunezinhlobo ezimbili ze-RAM, uhlobo lokuqala lwaziwa nge-SINGLE IN LINE MEMORY MODULE futhi lufushaniswe ku-“SIMM” okuwuhlobo oludala olwalusetshenziswa namadivayisi angama-486DX2, kanti uhlobo lwesibili lwaziwa nge-DUAL IN LINE MODORY, ngokufushanisiwe. njenge-DIMM futhi ihlukaniswe ngezinhlobo ezintathu, okuyi-SDRAM DDRAM ne-RDRAM.
Uhlobo lokuqala luthi “Single Data Rate Random Access Memory”, esifushanisiwe ngokuthi “SDRAM”, okungenye yezinhlobo ezindala kakhulu futhi cishe akukho ukusetshenziswa kwalolu hlobo esikhathini sethu. Lolu hlobo luguqula ulwazi ngesivinini esibuthakathaka kakhulu futhi esilinganiselwe futhi lusebenzisa inani elikhulu lamandla.
Uhlobo lwesibili, i-Double Data Rate-Synchronous DRAM, ifushanisiwe njenge-DDRAM. Lolu hlobo lwenza ukusebenza okuphezulu okuphindwe kabili kohlobo lokuqala ngaphezu kokusebenzisa amandla amancane futhi lunezinhlobo ezintathu ezihlukene, okuyi-DD-RAM I - DD-RAM II - DD-RAM III emele i-DDR1 - DDR2. Imemori ye-DDR3.
Uhlobo lwesithathu, okuyinkumbulo yokufinyelela engahleliwe eguquguqukayo ye-Rambus kanye ne-“RDRAM” efushanisiwe “I-Rambus Dynamic Random Access Memory”, ibonakala ngesivinini esikhulu kanye nenani eliphakeme kunezinye izinhlobo ezishiwo emigqeni engenhla, futhi igxile kakhulu ukusabalalisa nokudlulisa idatha phakathi kwememori nephrosesa endaweni engaphezu kweyodwa. Inkampani imise lolu hlobo ngenxa yezindleko zayo eziphezulu ngaphezu kokuthi i-DDR2 inemiphumela eqinile nenani eliphansi.
Umehluko phakathi kwezinqama ddr1 - ddr2 - ddr3 - ddr4
I-DDR1: Uhlobo oludala nolungavamile, inguqulo yokuqala ye-ddram.
I-DDR2: Lolu hlobo luvame kakhulu futhi lutholakala emibhalweni eminingi futhi lusetshenziswa njengeprosesa kumakhompuyutha edeskithophu nakulapthophu futhi, lolu hlobo luwonga amandla futhi lunogesi ofinyelela ku-1.8 GHz.
I-DDR3: Lolu hlobo lufaneleka kakhulu kuma-laptops futhi lunezinzuzo zokwandisa isivinini sokusebenza ngenkathi kunciphisa ukusetshenziswa kwamandla, kodwa intengo yalo iphezulu uma iqhathaniswa ne-DDR2.
Isihloko sesiphelile, ngiyakubona, mfundi othandekayo, kwezinye izihloko
