    The same as with any PC...

    RAM - applications in use
    ROM - permanent storage

    You most likely will never see a RAM upgrade.

    If you need more ROM, install a larger MicroSD card.

    DROID has 256 mb of RAM and 512 mb ROM. All 256 mb of RAM are available for running processes, including those needed by the OS and system. Of the 512 mb ROM, I believe that 230 mb are available to the user for app storage, while the rest is for the OS and system. Then of course, there is the microSD ROM, of which 15 gb are user-accessible.

    They are currently not upgradeable, except for the microSD card. Until Google releases a native Apps2SD, the microSD card won't be good for anything except pictures, music and saved files. RAMhacks have "opened up" RAM on some phones. The OS will always use a certain amount of RAM at all times. For example, the big deal with the N1 right now is that only 190mb of its 512mb of RAM is freed up for user processes. DROID is only marginally more (~220mb). An updated kernel for the N1 will free up an additional 100-150 mb.

    in engineering classes it was

    RAM - Random Access Memory, that writes and reads
    ROM - Read Only Memory, that only reads and doesn't get written to


    Not sure if it means the same with these phones nowadays

    i know what the acronyms mean, lol...was wondering where our installed apps go, so i guess to ROM...downloads go where? to the SD card in the downloads folder?

    so no way to upgrade the RAM, understandable....and can't we use the SD card instead of the rom?

    32gb when they come out should be plenty, lol...

    ^^ You cannot install apps and run them from the SD card today without rooting your device. Google has said this is coming sometime in the future.

    Installed apps go onto the ROM. Some applications are able to store data on the SD card to retrieve. This is one of the things that people hope developers can use instead of having to have an Apps2SD situation. IOW, while Google shuffles their feet and twiddles their thumbs about Apps2SD, developers can create applications that use the ROM as boot-up for their apps, storing necessary run data on the SD card.
