| Lesson Topic: Know and understand characteristics, uses, media, advantages and disadvantages of storage devices including magnetic, optical and solid-state |
Learning Objective/s:
- Describe the characteristics and media types of magnetic, optical, and solid‑state storage.
- Compare the advantages and disadvantages of each storage technology.
- Identify appropriate use‑cases for each storage device based on capacity, speed, and cost.
|
Materials Needed:
- Projector or interactive whiteboard
- Slide deck covering magnetic, optical, and solid‑state storage
- Sample media (HDD, DVD, USB flash drive)
- Handout with comparison table
- Worksheet for the checklist activity
- Whiteboard and markers
|
Introduction:
Start with a quick poll: which storage device do you use most at home? Review students’ prior knowledge of basic data storage, then state the success criteria – they will be able to describe, compare, and select suitable storage media.
|
Lesson Structure:
- Do‑now (5') – Students list the storage devices they own and share one advantage of each.
- Mini‑lecture with slides (15') – Overview of characteristics, media types, common uses for magnetic, optical, and solid‑state storage.
- Group activity (10') – Using the provided comparison table, groups fill the checklist and discuss advantages/disadvantages.
- Physical demonstration (10') – Show sample HDD, DVD, and USB flash drive; discuss handling and durability.
- Whole‑class discussion (5') – Evaluate scenarios and decide which storage type is most suitable.
- Exit ticket (5') – Each student writes one storage choice for a given scenario and justifies it.
|
Conclusion:
Recap the key differences in capacity, speed, and durability among the three technologies. Collect exit tickets to assess understanding, and assign homework to research an emerging storage technology such as NVMe over Fabrics.
