Q

What is an example for a storage of contant values regarding RAM?

A

A digital device that stores the safe temperature limit so when temperature exceeds that value, alarms go off. The temperature is known as a constant value because it cannot be changed

Q

Which one is seen to be more beneficial - EAROM or EPROM ? And why

A

EAROM is better as it is seen as a benefit to be able to change individual elements of the memory rather than having to erase it and reprogramme everything like the EPROM does
