Detailed explanation-1: -ROM contains the programming that allows a computer to start up or regenerate each time it is turned on. ROM also performs large input/output (I/O) tasks and protects programs or software instructions. Once data is written on a ROM chip, it cannot be removed.
Detailed explanation-2: -ROM, which stands for read only memory, is a memory device or storage medium that stores information permanently. It is also the primary memory unit of a computer along with the random access memory (RAM). It is called read only memory as we can only read the programs and data stored on it but cannot write on it.
Detailed explanation-3: -The program of the microcontroller is stored in the memory. There are two types of memory: RAM (Random Access Memory) which can read and write data, and ROM (Read Only Memory) which mainly stores programs as read-only data. There are various types of RAM and ROM depending on the usage.
