common types of storage

What are the three common types of storage mentioned?

• Magnetic, Flash, and Optical

• Cloud, Optical, and Magnetic

• Solid-State, Flash, and Cloud

• Optical, Magnetic, and Solid-State

What device reads and writes data from secondary storage?

• The motherboard

• The RAM

• The drive

• The processor

Which optical storage media has the greatest storage capacity?

• CD-RW

• DVD-R

• CD-R

• Blu-ray

What makes a media read-only in optical drives?

• The surface of the disc is physically burned by the laser

• The disc is made of a special material that cannot be altered

• A reversible chemical reaction changes the chemical composition

• Data is encrypted and cannot be rewritten

Why do DVDs store more data than CDs?

• Because they are larger in size

• Because the pits and lands are smaller and closer together

• Because they are double-sided

• Because they use a different type of laser

What is a characteristic of magnetic hard disks?

• They have an extremely high capacity

• They are the most expensive type of storage

• They are the slowest type of storage

• They have no moving parts

What is a disadvantage of magnetic tapes?

• They have no moving parts

• They are not portable

• They can only be read and written sequentially

• They can only store a small amount of data

What is a limitation of solid-state drives?

• They have a limited number of read-write cycles

• They are noisy

• They have moving parts that fail

• They require frequent defragmentation

Why are solid-state drives considered very reliable?

• Because they have moving parts

• Because they operate without noise and have no moving parts

• Because they have a high storage capacity

• Because they are cheap to produce

What technology is used in solid-state drives to store data?

• Magnetised compounds

• Optical reflections

• Electrons in floating gates

• Physical burning of the surface
