DIMM happens to be the size of the slot where you apply the SDRAM, DIMM is typically a 168-pin slot which is probably what you have if you have a most up to date or current motherboard. In older motherboards, you find SIMM slots which have only 72 pins. Basically, you are able to use much more memory today than like before. if you are using windows operating system you can go to the help section and enter the word DIMM in the search. This should get you started on a more clearer idea and as well lead you towards more information to your question.
Ddr dimm has 184 Sdram dimm has 168
DIMM is the connection interface for RAM (SDRAM, RDRAM etc.) On a motherboard, there are several DIMM "slots" in which various RAM types are inserted.
SDRAM has 168 pins
: A SDRAM DIMM has 168 Pins : A DDR DIMM has 184 Pins : A SIMM has 30 or 72 Pins : A RIMM has 184 or 168

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.
You're computer will require a "DDR2 SDRAM DIMM". DDR2 SDRAM is the type of memory you are after, it is also a DIMM. Most modern memory are all DIMM's (Dual inline memory module), much older ram were SIMMS (single ingline memory module). DIMM refers more to the physical make up of the module (DIMMS have contacts on both sides of the module). So any DDR2 SDRAM that you buy IS a dimm. You may want to look at the wikipedia page about DDR2 SDRAM at http://en.wikipedia.org/wiki/DDR2_SDRAM
The positions of two notches on a SDRAM DIMM identify the type of DIMM and the voltage requirement and also prevent the wrong type from being installed on a motherboard.

Variants of DIMM slots support DDR, DDR2 and DDR3 RAM. The most common types of DIMMs are: 72-pin SO-DIMM (not the same as a 72-pin SIMM), used for FPM DRAM and EDO DRAM. 100-pin DIMM, used for printer SDRAM.
Yes. For example the iMac uses PC2-5300 DDR2 SO-DIMM SDRAM memory.
It depends upon the motherboard, but generally, motherboards only support one type of memory. If you have SDRAM now, chances are that DDR will not work. The DIMM slots for SDRAM and DDR are not the same, so only one kind will fit.
Synchronous DRAM (SDRAM)
Common types of DIMM Memory Modules used in computers are a 168 pin SDRAM Module, or a 184 pin DDR SDRAM. These boards are designed to be used in personal computers.
All memory modules have an identification code to enable the correct dimm to be used. The code has never been designed to give any other information than the SDRAM on the DIMM. Only by going to the manufactures DATA specification sheets can voltage, dwell times, etc be found
