Users can not modify data stored on ROMs for example, a program that manages the operation of your Air Conditioner at home or workplace, stock programs and default settings (kernel) on your mobile device, software that run video game consoles, and so on.
Manufacturers use ROMs whenever they need to store sensitive data on electronic devices or some part of a software. ROMs are very distinctive because the data that is stored on them cannot be electronically erased or changed after it has been created. The Read-only Memory (ROM) is usually used both on computers and other electronic devices, including MP3 players, Bluetooth headsets, radio sets, and others for storing sensitive data.
