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.
