What type of memory is non-volatile, considered permanent, and is also called firmware in reference to the data and instructions stored?
- A.
Cache
- B.
Read-only memory (ROM)
- C.
Random access memory (RAM)
- D.
Complimentary metal-oxide-semiconductor (CMOS)
Correct Answer
B. Read-only memory (ROM)Explanation
ROM is a type of memory that is non-volatile, meaning it retains its data even when the power is turned off. It is considered permanent because the data and instructions stored in ROM cannot be easily modified or erased. ROM is also referred to as firmware because it contains the essential instructions needed for the computer system to boot up and initialize hardware components. Unlike RAM, ROM is not directly accessible by the CPU and is used primarily for storing critical system software and firmware. Therefore, ROM is the correct answer to the question.Rate this question:

- A.
Read-only memory (ROM)
- B.
Random access memory (RAM)
- C.
Programmable read-only memory (PROM)
- D.
Complimentary metal-oxide-semiconductor (CMOS)
Correct Answer
C. Programmable read-only memory (PROM)Explanation
PROM is a type of memory that allows instructions to be permanently placed on it. Unlike RAM, which is volatile and loses its data when power is turned off, PROM retains its information even when power is removed. ROM, on the other hand, is not programmable and contains instructions that are permanently embedded during manufacturing. CMOS is a type of technology used in integrated circuits and does not refer to a specific type of memory. Therefore, PROM is the correct answer as it meets the criteria of being programmable and retaining instructions permanently.Rate this question:
