No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
The term DDR SDRAM refers to the phrase "double data rate synchronous dynamic random access memory". DDR SDRAM is simply a faster version of SDRAM in which data travels at a double rate. If your computer specs say that it uses DDR SDRAM it can take DDR SDRAM, but not SDRAM. DDR is 184 pins and has a notch in the bottom near the center and you will be unable to put DDR in an SDRAM mother board and also unable to put SDRAM in a DDR motherboard. Recently a new type of RAM has been introduced to market called DDR2. DDR2 is its own type and will not fit into a DDR motherboard. Hope this helps. Peace.

168 pins are used on SDRAM DIMM. 184 pins are used on DDR DIMM. There are either 30 pins or 72 pins used on SIMM. 184 pins are used on RIMM.
depending on the laptop, it could be DDR, DDR2 or DDR3. But the form factor is all the same. Its all SO-DIMM memory
The fastest technology in actual is laan, laan is the longest and most profound memory ever.
This is some specification for RAM modules: DDR3 240-pin DDR 2 240Pin DDR 184 Pin SDRAM 168-pin SODIMM 200-pin DDR2 SODIMM 200-pin DDR,DDR2 and DDR3 have 2 holes SDRAM have 3 holes
The number of pins at the bottom of the stick. Some ddr's have 184 pins, some newer models have 240, starting with DDR2.
2.66" 189-pin SO-DIMM contains DDR SDRAM 2.66" 189-pin SO-DIMM contains DDR2 SDRAM 2.66" 145-pin SO-DIMM contains SDRAM 2.35" 40-pin SO-DIMMs (outdated) 130-pin SO-RIMM (conatains Rambus memory and has two notches).
No. SDRAM and DDR SDRAM are not compatible with each other.
DDR2 RAM is SDRAM. It provides double the bandwidth of DDR RAM, but at a higher latency. DDR3 is much better than DDR2 performance-wise, and it uses less voltage.
