-> ## Operating system (_Custom ROMs_)

_ROM (Read-Only Memory):_

Originally, the term ROM referred 
to a type of computer memory where 
**data could only be read, not written or modified.**
In the context of mobile devices, 
"ROM" has come to refer to the firmware or operating system 
software that is installed on the device. 
This includes the core Android operating system along with 
any additional software and customizations 
made by the device manufacturer.
