Most ROM chips are used to store
Correct answer: C. Data which is not changed for longer periods of time
- A. BIOS
- B. OS routine
- C. Data which is not changed for longer periods of time
- D. All of these
Explanation
BIOS (Basic Input/Output System) is a firmware program that is stored in a ROM chip on a computer's motherboard. It provides low-level instructions for starting the computer and initializing devices. However, BIOS can be updated in some cases. So, option (a) is incorrect.OS routines (Operating System routines) can also be stored in ROM, but modern operating systems are typically stored on hard drives or solid-state drives, which are not ROM. So, option (b) is incorrect.ROM (Read-Only Memory) is a type of non-volatile memory that retains its data even when the power is turned off. It is commonly used to store data that is rarely changed, such as firmware, configuration settings, and lookup tables. So, option (c) is correct.Therefore, the most common use of ROM is to store (c) Data which is not changed for longer periods of time.
