question about DDR3 memory in a DELL Inspiron

So I have (at my warehouse) three Dell laptops:

I bought them here:
Two of these:
Dell Inspiron 17.3-Inch Laptop (i5748-4000SLV)

one of these
Dell Canada i17RM-67756sLV 17.3" i7 3537U 8GB 1TB

So I want to upgrade the memory.
According to specs on NewEgg, they have DDR3 memory. Which I honestly don't know what that all means.

I guess to simplify the question, would this memory work if I were to buy it?:

Basically I don't need much technical explanation, as I won't understand it. But a YES or NO will do nicely!

Also, the computers are physically in another country so please don't ask me to look at numbers on them or open the up.

Thanks guys!
