Which of the following is an essential role of ROM in a computer system?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Storing data permanently for boot-up processes.
ROM (Read-Only Memory) is a type of non-volatile memory that permanently stores data in a computer system. It holds the firmware or the basic instructions required to boot up the system and start the operating system. ROM data is written during manufacturing and cannot be modified or erased by normal computer operations
Storing data temporarily: This is the role of RAM (Random Access Memory), which is volatile and loses its data when power is turned off.
Performing calculations: This is done by the CPU (Central Processing Unit).
Storing files created by the user: This is done by storage devices like HDDs, SSDs, or other types of non-volatile storage.
