Help Memory memory memory - what does what?

[simonwootton]

Just a general question about the memory with the S2. USB memory, SD memory etc. I have a 2Gb SD card installed, but what is each memory type used for and how can I (if possible) decide on what is used where ..... Just a little confusing to a newbie!

This sticky above, entitled, "Samsung Galaxy S2 Guide:", contains the thread, "SDcard and internal memory got me confused", which explains the various memories and contains links to further explanations.
