ROM is primarily used for which of the following purposes?

Correct option is B

ROM (Read-Only Memory) is primarily used for storing the BIOS (Basic Input/Output System) or firmware in a computer. Unlike RAM (Random Access Memory), which is volatile and loses data when powered off, ROM is non-volatile, meaning it retains its data even when the power is turned off. The BIOS or firmware stored in ROM contains essential instructions for starting up the computer and allowing it to communicate with hardware components.
Important Key Points:
1. Non-Volatile Memory: ROM retains data even when the computer is powered off, making it ideal for storing firmware and system-level instructions.
2. BIOS/Firmware Storage: The BIOS, which is a critical piece of firmware, is stored in ROM and provides basic instructions for the system’s startup process.
3. System Initialization: ROM is used to store the essential code that allows the computer to initialize hardware and load the operating system.
Knowledge Booster:
· Random data access: This is more typical of RAM, not ROM. ROM is designed for reading stored data, not for random access or writing data.
· Storing files for permanent access: This is typically done using storage devices like hard drives, SSDs, or flash memory, not ROM.
· Temporary data storage: Temporary storage is typically handled by RAM, which is volatile and stores data temporarily while the computer is running.
