Answer 1

Disk is a secondary memory device.

It cannot be processed directly by the CPU. It must first be copied into primary storage (also known as RAM). Secondary memory devices include magnetic disks like hard drives and floppy disks ; optical disks such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.

Because the RAM is connected directly to the CPU via the memory bus, the CPU can access data stored in RAM very quickly. ... While the computer's primary internal hard drive is the most common secondary storage device, other devices may be considered secondary storage devices as well.

Answer 2

Answer:

D. (iii). Hard disk

E. (ii). EEPROM

F. (i). Cache memory

G. (iii). ROM

H. (ii). MRAM

Explanation:

D. Programs and data are stored permanently in secondary memory. The hard drive and floppy discs are two frequently used secondary storage media. When compared to main memory, the hard drive has a huge storage capacity. Typically, a device's system unit houses the hard disc.

E. EEPROM refers to the kind of ROM that may have its data erased by ultraviolet light.

F. Cache memory is the memory that briefly stores some data in order to speed up the CPU. The temporary store space known as cache helps the CPU run more quickly.

G. Non-volatile memory, or "read-only memory," is a type used in computers and other devices. After the memory device is manufactured, the data contained in the ROM cannot be electrically manipulated.

H. Data is stored in magnetic domains in magnetoresistive random-access memory, a type of non-volatile random-access memory. Magnetoresistive RAM, which was created in the middle of the 1980s, has its supporters believing that it will eventually surpass other technology becoming a dominant or even global storage.
