Q1:

What is the main advantage of magnetic core memory over semiconductor RAM memory?

A more compact and smaller

B more economical

C a bit does not have to write after reading

D non volatile

E None of the above

ANS:D - non volatile

Semiconductor Memory Ram is a Volatile memory (loses data when power goes OFF). Magnetic Memory is non volatile (doesn't not lose data when power goes OFF). Semi conductor memory is faster, economical, smaller in size and lighter, but magnetic memories are slower compared to that. Semi conductor memories consumes less power, but magnetic memory consumes more power than that.
