What is the best definition of 'semiconductor storage'?

a) a type of storage using integrated circuits to store data; examples include RAM, ROM, and flash memory;

b) a legacy storage device which can read and write data slowly from a removable magnetic medium (normally 3.5" in diameter and holding 1.44 MB of data);

c) a legacy storage device using magnetic ribbon inside a plastic cassette.

What is the best definition of 'hard disk drive'?

a) a storage device using rotating magnetic platters to quickly store and retrieve digital data;

b) a type of storage using integrated circuits to store data; examples include RAM, ROM, and flash memory;

c) a newer data storage device meant to replace a traditional hard disk drive; these are characterized by speed, non-moving parts, and lower energy consumption.

What is the best definition of 'EPROM' or 'erasable programmable read only memory'?

a) a type of memory which is known for being non-volatile (permanent) and fast;

b) a legacy storage device which can read and write data slowly from a removable magnetic medium (normally 3.5" in diameter and holding 1.44 MB of data);

c) a non-volatile (permanent) memory type that is erasable via ultra-violet light and reprogrammable.

What is the best definition of 'optical storage'?

a) a data storage technique using a pattern of markings on a disc that can be read by a laser; examples include CD-ROM, and DVD-ROM technology;

b) a type of memory which is known for being non-volatile (permanent) and fast;

c) a type of storage using integrated circuits to store data; examples include RAM, ROM, and flash memory.

What is the best definition of 'magnetic storage'?

a) a storage device using rotating magnetic platters to quickly store and retrieve digital data;

b) a type of memory which is known for being non-volatile (permanent) and fast;

c) a storage technique using patterns of charged particles on a metallic surface to store data; examples include hard disk drives, tape drives, floppy disk drives.
