Computer Memory and Storage Quiz

What is the function of primary memory in a computer system?

• To scan the surface of a spinning disc made from metal and plastic

• To magnetise tiny individual sections of a metal spinning disk

• To store data indefinitely

• To hold data and programs that are currently in use

Which of the following is a common type of secondary storage device?

• Hard disk drive

• Optical media

• Solid state drive

• Random access memory

How do magnetic storage devices represent binary data?

• By magnetising or demagnetising tiny sections of a metal spinning disk

• By reflecting or scattering laser beams on a disc surface

• By using non-volatile random access memory

• By dividing the disc surface into tracks with flat areas and hollows

What is a disadvantage of magnetic storage devices?

• They are susceptible to damage if dropped

• They have slower access times compared to other types of devices

• They are more expensive than other types of devices

• They require more power to operate

How do optical storage devices represent binary data?

What is a characteristic of ROM media?

• They can be written to more than once

• Data is pre-written on them and cannot be overwritten

• They have faster access times compared to other types of media

• They use non-volatile random access memory

What is a characteristic of solid state devices?

• They use magnetic fields to magnetise tiny sections of a metal spinning disk

• They have slower access times compared to other types of devices

• They require more power to operate

• They have no moving parts and are more durable

What is a disadvantage of solid state devices?

• They are susceptible to damage if dropped

• They are more expensive than other types of devices

• They are vulnerable to magnetic fields

• They tend to be smaller in capacity compared to other types of devices

Which type of storage device is ideal for portable devices with limited battery life?

• Random access memory

• Solid state devices

• Magnetic storage devices

• Optical storage devices

What is a characteristic of optical storage devices?

• They use magnetic fields to magnetise tiny sections of a metal spinning disk

• They have slower access times compared to other types of devices

• They require more power to operate

• They use laser beams to read and write data
