Can A Computer ROM Be Rewrite?

The ROM in a computer cannot be rewritten in any way because it can’t really be destroyed, so there’s nothing left to rewrite. This is similar to what happens when data is stored for a prolonged period of time on magnetic media or optical discs – the recorded information doesn’t degrade. Magnetic particles lose their magnetism over time, but all the ones near each other still point outwards after 10 years for example.
