There are no disadvantages, both are the same. Using one 2gb stick of memory will allow you to add another memory upgrade in the future.
No. The RAM (in the DIMM) is a storage area. The CPU performs mathematical operations.

A DDR3 DIMM has three notches - one on each end (which matches the retaining springs on the motherboard socket) - and one offset notch on the row of connector pins - to ensure you insert it the correct way into the socket.
Yes. The Intel CC820 motherboard has two DIMM slots that can use two single-sided DIMMs , two double-sided DIMMs or one single-sided DIMM and one double sided DIMM. In that case, the single-sided DIMM must be in the first slot.
<new answer> The old answer is completely incorrect, it does not tell you about the pins. The 72 indicates that the DIMM is ECC <old answer>72 pin

SO-DIMMs are smaller then regular DIMM so are suited for laptops where space is at a premium. Speed and power is similar to DIMM size memory.
SIMMs are pretty much obsolete. DIMMs are the currently popular choice for desktop style computer memory. (Laptops use SO-DIMMs.)
Single-ranked DIMMs cost more but perform better b/c the controller accesses all chips at the same time.
You can get memory dimms as big as 4 gigabytes and your computer will have three or four slots for a dimm.
Some systems use dual memory channels to access ram, if you dont have a pair of memory sticks, it cant work in dual mode, thus not allowing the system to boot. You can buy special DIMM plugins that fool the computer into thinking there are a pair of DIMMs. The other issue could be if your using registered DIMMs in with unregistered DIMMs
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.

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DDR SDRAM 2.66" 189-pin SO-DIMM contains DDR2 SDRAM 2.66" 145-pin SO-DIMM contains SDRAM 2.35" 40-pin SO-DIMMs (outdated) 130-pin SO-RIMM (conatains Rambus memory and has two notches).
dimm is better, dimm is faster, most motherboards is designed to work with this type of memory..
