Which of the following is an example of optical media?

• CD.

• Magnetic hard drive.

• Paper.

• SSD.

Answer explanation

Optical media refers to devices like CDs and DVDs, which store data using light, unlike magnetic or solid state storage.

What is a primary disadvantage of paper storage media?

• High storage capacity.

• Requires digital devices to access.

• Easily damaged or lost.

• Fast data retrieval.

Answer explanation

Paper is easily damaged, can deteriorate over time, and is less secure than digital media.

Which of the following is a solid state media?

• Magnetic tape.

• SSD.

• DVD.

• CD.

Answer explanation

Solid state drives (SSD) are an example of solid state media, which use flash memory to store data.

What is the main characteristic of magnetic media?

• Stores data using magnetic fields.

• Stores data using light.

• Uses ink and paper to record data.

• Uses flash memory.

Answer explanation

Magnetic media, like hard drives and tapes, store data by magnetizing particles on a surface.

Which of the following is an advantage of solid state media?

• High durability and resistance to physical shock.

• Low cost compared to other storage media.

• High risk of data loss.

• Low data transfer speeds.

Answer explanation

Solid state media, such as SSDs, are durable and resistant to shock, making them more reliable for physical environments.

Which of the following is a disadvantage of optical media?

• Expensive to manufacture.

• Vulnerable to scratches and damage.

• High storage capacity.

• Very fast read/write speeds.

Answer explanation

Optical media like CDs and DVDs are vulnerable to physical damage, such as scratches, which can lead to data loss.

Which storage media is most suitable for long-term archival purposes?

• Magnetic tape.

• Paper.

• Optical media.

• SSD.

Answer explanation

Optical media, especially DVDs or Blu-rays, are often used for long-term storage due to their durability and cost-effectiveness.

What is one major advantage of magnetic hard drives over SSDs?

• Faster data access.

• Lower cost per gigabyte.

• More resistant to damage.

• Longer lifespan.

Answer explanation

Magnetic hard drives are generally more affordable per gigabyte compared to SSDs.

What is the primary purpose of using paper as a storage medium?

• Long-term archival of sensitive data.

• Temporary recording of information.

• High-speed data processing.

• Large-scale data storage.

Answer explanation

Paper is typically used for temporary information recording, such as forms or handwritten notes.

Why are SSDs preferred over HDDs for portable devices?

• Higher storage capacity.

• Lower cost.

• Faster read/write speeds and durability.

• Compatibility with older systems.

Answer explanation

SSDs have faster read/write speeds and are more durable, making them ideal for portable devices like laptops.
