Answer 2

1. Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs. So, the statement "Secondary memory is also called Auxiliary memory" is false.
2. Magnetic tape is a secondary storage device. The CPU is unable to access it directly. In most cases, a computer accesses secondary storage via its input/output channels and transfers data to primary store via intermediate storage. So, the statement is true.
3. Mainframe computers use Optical disks for storage. This statement is false.
4. On Magnetic discs data is stored on both sides. Magnetic disks are flat circular plates of metal or plastic, coated on both sides with iron oxide. This statement is true.
5. WORM stands for Write Once Read Many. Write once read many (WORM) refers to a data storage medium in which information can't be changed after it's been written. This write protection ensures that once data is written to the device, it cannot be tampered with. So, the statement "WORM stands for Write Once Read Many" is true.
