The Samsung has developed lots of smartphones and tablets which require a certain system software and that’s called an “Operating System” or OS. Most of the Samsung smartphones and tablets are compatible with Android OS, like Apple devices are running iOS, Nokia is running Windows OS and etc. Now what is a ROM?
It stands for Read-Only Memory, and a ROM is the image of a OS that’s already been installed on your phone or tablet devices that refers to the (Firmware of the device or internal storage of a device which contains the operating system instructions that wouldn’t be needed in a normal operation, as well as it is a read-only memory means you couldn’t make changes to it. A Firmware and ROM are the same, which can be modified but not under normal usage, like to make changes or flash it (install ROM) you need to access it from an advanced device such as PC to install the ROM.
And what do we need to do with ROM? So, here flashing comes, it means to install or modify the firmware of a device and the Stock ROM (Official/Original Firmware) are those which comes by default in devices and they are customized by a specified company, also a ROM is important in a device because without that a device can’t operate. There are two kinds of ROMS:-
* Stock ROMS:- This is the operating system in its default mode without any changes required to run in it. It provides the standard, original user experience of the OS without any functional changes made.
* Custom ROMs:- It is used for custom developers that go beyond the standard and wants to taste their own fruit they grow. In fact, custom ROMS development for the otherwise proprietary and closed-source Windows Mobile platform lead to the formation of the largest independent mobile development community.
