3.1.2 Hardware Storage Devices Quiz

What is the primary purpose of secondary storage?

• To temporarily hold data that is currently being processed

• To permanently store data and programs for long-term use

• To process instructions in the CPU

• To manage the system's power supply

Which of the following is an example of magnetic storage?

• DVD

• SSD

• Hard Disk Drive (HDD)

• USB flash drive

How does optical storage, such as a CD or DVD, store data?

• By using magnetic fields to represent data as 1s and 0s

• By using flash memory cells to store data

• By using lasers to read and write data as patterns of pits and lands on the surface

• By using electrical charges to store data

Which of the following is a characteristic of solid-state drives (SSDs) compared to hard disk drives (HDDs)?

• SSDs have moving parts; HDDs do not

• SSDs are typically slower than HDDs

• SSDs consume more power than HDDs

• SSDs are faster and more durable than HDDs

Which type of storage device is most commonly used for backing up large amounts of data?

• Optical storage (e.g., Blu-ray disc)

• Magnetic storage (e.g., external hard drive)

• Solid-state storage (e.g., SSD)

• Cloud storage

What is a disadvantage of using optical storage?

• It has a low storage capacity compared to other methods

• It is highly susceptible to magnetic fields

• It has a higher data transfer speed than SSDs

• It is more expensive than SSDs

How is data stored in a solid-state drive (SSD)?

• Data is stored using magnetic fields

• Data is stored in flash memory cells using electrical charges

• Data is stored as pits and lands on a reflective surface

• Data is stored using a laser beam

Which type of secondary storage is typically used in portable devices like smartphones and tablets?

• Magnetic storage

• Optical storage

• Solid-state storage

• Tape storage

Why are magnetic storage devices like HDDs still widely used despite the availability of SSDs?

• They are faster than SSDs

• They are more durable than SSDs

• They offer higher storage capacities at a lower cost

• They use less power than SSDs

Which of the following is an example of an optical storage device?

• USB flash drive

• Blu-ray disc

• Solid-state drive

• External hard drive
