The Differences between ROM and RAM include: generally, the non-volatile memory maintains the data whenever the computer is turned off, while ROM is utilized to store some necessary instructions, like firmware or a bootloader, in order to control the computer and initate it. Usually written during manufacturing once, and later hard to change.
On the other hand, RAM is a volatile memory that loses its stored data whenever the system is powered down. It temporarily holds data the processor will use while running applications and operating system processes. Data that is stored on RAM can be read from and written to really fast; hence, RAM is crucial when it comes to system performance.
Whereas ROM is mainly used to store fixed system instructions that do not change, RAM is employed for the temporary storage of data that may change while operating the system.
