http://en.wikipedia.org/wiki/DDRAM http://en.wikipedia.org/wiki/SDRAM It explains everything.
No. SDR SDRAM and DDR SDRAM modules are not interchangeable.
No. SDRAM has two notches and DDR SDRAM has only one so besides all the electrical incompatibilities it won't physically fit.
Sorry.. its either / or syndrome. If the motherboard, has DDR then it would be best to utilise this. As it is probably twice as fast as normal SDRam.
Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.
Obviously the difference is speed.
Dram and Sdram are two different types of memory.
The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.
DDRAM is an Acronym for Double Data Random Access Memory.
It's the same thing, Synchronous Dynamic RAM (SDRAM) is typically just a different name for DRAM.
speed?maybe.but more likely the spelling.."DDR2" has no"SDRAM PC2 133 168pin" unlike the"DDR2 SDRAM PC2 133 168pin"It's really hard to see it at a first glance..
The 3GB ram has one more GB than the 2GB RAM. From a user's point of view, that's 33.33 per cent more.
sd ram is synchronous dynamic random access memory, ram is just random access memory
