Final answer:
In most Palm OS devices, RAM and ROM are on separate memory modules. RAM is used for storing user data and applications, while ROM contains system firmware and some pre-installed apps.
Step-by-step explanation:
The memory arrangement on Palm OS operates with a combination of RAM (Random Access Memory) and ROM (Read-Only Memory). Typically in most Palm devices, RAM and ROM are not on the same memory module. The RAM, where user data and applications can be modified and stored temporarily, is usually on one chip, whereas the ROM, which contains the system's firmware and some pre-installed applications, is on another. This allows the device to preserve system software and important files that should not be changed even when the device is turned off or reset.
