ROM and RAM chips have distinct roles in the operation of devices like a microwave oven and refrigerator.
ROM (Read-Only Memory) chips in a microwave oven could be used to store the permanent instructions needed for its operation, such as the cooking programs and settings. On the other hand, RAM (Random-Access Memory) chips could be utilized to temporarily store data while the microwave is in use, like the time remaining or the current cooking stage.
In a refrigerator, ROM chips might hold essential system instructions, like the temperature control algorithms. RAM chips could serve to store temporary data, such as the current temperature readings or settings adjustments made by the user.
