Because today, this small white to use the android inside the Envirement class, to read the information inside the phone memory.

But has been tangled in the end what is the phone memory card, what is the built-in SD card, what is ROM, what is ram ...

Here is my summary, write the wrong place also please pass the Bo friends to give a lot of advice.

In my opinion:

What we normally call memory cards in my opinion can be divided into two categories: The phone comes with a memory card and a small black tf card (external memory card: can be inserted into the phone)

    • The phone comes with a memory card: This graph will be more intuitive

    • TF card: That is, we usually use, the card camera, or the old phone can be arbitrarily unplugged in the small black card, that is, the so-called external SD card

To summarize:

commonly said phone memory: For example, Xiaomi 2s has 32G version, refers to the size of the ROM is 32G.

ROM: Installed system memory + built-in SD card size

RAM: mobile memory (not normally referred to as memory), usually separately explained on the product manual

built-in SD card: just part of ROM

external SD card: A memory card that can be unplugged
