Which of the following statements about RAM and ROM with reference to computer memory is correct?

Correct option is D

The correct answer is (d) RAM temporarily stores data for active programs, while ROM permanently stores firmware

Explanation:

• RAM (Random Access Memory) is a volatile memory, which means its data is lost when the computer is turned off.
• It is used to temporarily store data and instructions for programs that are currently running.
• ROM (Read-Only Memory) is non-volatile, and it retains data even after power is turned off.
• ROM contains firmware, which is the pre-installed software that helps start the computer (like BIOS).
• Together, they play essential roles in system operation: RAM enables multitasking, and ROM ensures boot-up functionality.

Information Booster:

• RAM is read-write memory and can be accessed and modified frequently.
• ROM is read-only in normal operations but can be modified using special methods (e.g., flashing).
• RAM improves system speed and performance, especially with more installed capacity.
• ROM is used to store bootstrap programs and system-level instructions.
• Types of RAM: DRAM, SRAM; Types of ROM: PROM, EPROM, EEPROM.

Additional Knowledge:
RAM is non-volatile, while ROM is volatile (Option a)

• Incorrect; it’s the reverse — RAM is volatile, ROM is non-volatile.

ROM is faster than RAM (Option b)

• False; RAM is much faster in data access compared to ROM.

RAM cannot be written to, only read from (Option c)

• Incorrect; RAM is read-write memory, unlike ROM which is primarily read-only.
