About ROMs In Android Ecosystem
Android is an open source platform so it allows users to replace the stock ROM or re-installed the operating system with any compatible third-party ROMs. In computer language, the ROM stands for READ ONLY MEMORY that means you can not edit or delete the ROM. However, when it comes to Android there is a different meaning for the ROM. In Android, it means firmware of the device. Installing ROM on the Android device is as same as installing an operating system on a computer device. In the Android Ecosystem, there are two types of ROMs or Firmware exists. One is Stock Firmware which is provided by the manufacturer and comes pre-installed with the device and the second one is Custom ROM which is developed by third-party developers or team. Most of the cases, Stock Firmware is more stable compared to the Custom ROMs whereas Custom ROMs provides more features and updates compared to the Stock ROM
