Understanding RAM, SD Card and Device Memory of an smartphone
I have an Android smartphone and would like to understand what is the difference between RAM, SD Card and Device Memory.
When I check Memory Usage of my smartphone, I see those components:
RAM: 174 used and 52 MB free
On SD Card: 492 MB used and 3.16GB free
Device Memory: 143 MB used and 47 MB free
I understand that "SD Card" is some external memory that you put in the Smartphone. But how do I understand RAM and Device Memory?

@Joshua > You right Device memory can not expand however If you have 8 GB Device memory + 8 GB SD that make usable memory Total = 16 GB , Out of 16 GB apx. 4 GB occupied by OS & Flesh
Yea, completely aware of how that works. That wasn't the question asked in the original post. Over explaining an answer does not help them understand.
RAM is used by running processes on an as-needed basis. The biggest thing for SDK apps to note is that there is an upper bound as to how much RAM a process can consume
Device Memory is perceived to be the flash that is used to store APKs, ROM images, etc.
RAM stand 4Random Access Memory. It is d memory ur fone needs to run applications smoothly. Every file or app u open take up certain space 4rm ur RAM. Were d whole Ram is exhausted u wil have to close sum running apps to allow d running of another. Basically a fone of 1GB RAM wil allow d runnin of more apps at d same time dan a fone wit 515MB RAM while ur internal memory is d fone memory were u store ur music, videos, games etc, d internal memory can be expanded using memory card of ur choice size.
