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.
