SIMMs , DIMMs, RIMMs, SDRAM, SO-DIMMs, MicroDIMMS, RAM, ROM, Dual-channel, single-channel, DDR, DDR2 /3.
I can memorise all these acronyms and definition about the above and answer any exam question that have seen so far, but I still donít know what they are.
Is there any physical aspect (Size, shape, weight, color) that determines which type of memory module (or memory slot) each of them is?
By looking at each can you tell if it is RAM or DDR, ROM or SIMM, RAM or SDRAM, Dual-inline or Dual-channel ? (this question should show my confusion)
Where the difference is nothing to do with physical shape, appearance or else. Can please advise what determines, for instance if the memory is ROM or RAM.
I think this would help me clarify the definitions of different memories that I had to learn by heart without being able to understand.
Your help would be greatly appreciated.
Thank you in advance.
