RAM stands for Random Access Memory, and it is the RAM that allows you to operate more than one program at a time on your computer. The more RAM you have, the faster your computer will be able to run programs. SD RAM was used on computers built some years ago, but manufacturers have moved on to using DDR RAM (double data rate ram), which operates faster. RD RAM is used on a limited number of computers.

DDR RAM is memory that was commonly used as the main memory in computers and printers several years ago. There are a number of different variations on it:
DIMMs are the typical desktop sized modules, 184 pins and about 5" long
SODIMMs are a smaller package for laptops, 200 pins and about 2" in length
MicroDIMMs were used in a very few laptops
No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
ram doesn't use a cable, but sd and ddr are not compatible
There is two types. There is DDR notebook RAM and there is DDR desktop ram. They can't be used vin each other (notebook RAM can't be used in a desktop) unless (in rare circumstances) you happen to have a notebook ram port on your desktop's motherboard. But no, DDR is a technology. Both desktops and notebooks support this technology because there is notebook DDR and desktop DDR. but notebook DDR can't be put in desktop DDR and vice versa.
ddr ram 3
no...you can't
By an order of 2.
If the motherboard supports both DDR and SDR RAM, it is almost always a better idea to go with DDR RAM
Ddr ram
SD RAM and DDR RAM
It's much faster. it has speeds up 1333hz and up.
No, they're not cross compatible. 184pin DDR is desktop memory, 200 pin ddr is a SO-DIMM, which is laptop memory.
It's the same thing.
