Can someone explain what DDR, SODIMM, DIM mean, differences?
Sure.
First, I should explain how memory works.
Memory is a place that the computer stores information that it needs to access quickly. Your standard hard drive transfers data MUCH slower than the memory does.
So instead of waiting for the hard drive it loads the info into the memory so it can be accessed faster. It would be like putting your wallet into your glove compartment as opposed to your trunk. If you need that wallet quickly, it is easier to get to it if it is in reach.
That said, the differences between the types of memory is important to know.
First, your standard type of memory these days are DIMM memory which stands for Dual Inline Memory Module. That is opposed to the older SIMM memory stands for “Single” inline memory module.
After that, there are other classifications have to do with their data speed. SDR is Single-data rate and DDR means Double-Data rate. As you can guess DDR has twice the data transfer rate.
SODIMM is a term that applies to laptop memory. The “SO” prefix stands for “Small Outline”.
