Mobile Rom
In case of mobile ROMs are the low level programming (also often called firmware) that contain the operating system and basic applications to make your phone work.

Firmware refers to the applications and operating system that control how a cellphone or smartphone operates. It is called firmware rather than software to highlight that it is very closely tied to the particular hardware components of a device.
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
If you ever do the hardware setup procedure with your computer, you effectively will be writing to ROM.
