• B. Magnetic disks
• C. Magnetic drums
• D. Magnetic tapes
• E. None of the above

Answer 1

The correct option is A Semiconductor memory

Semiconductor memory is not used as secondary storage.

Semiconductor memory is a digital electronic data storage device, often used as computer memory, implemented with semiconductor electronic devices on an integrated circuit (IC).

All semiconductor memory, not just RAM, has the property of random access. Volatile memory loses its stored data when the power to the memory chip is turned off. ... This type is used for the main memory in most computers, since data is stored on the hard disk while the computer is off.
