   • Discuss the importance of secondary storage devices in computing.
   • Emphasize that they provide a way to store data permanently, allowing users to save files and access them even after shutting down the computer.
   • Use real-life examples to illustrate the significance of secondary storage devices.
3. Comparison Activity (5 minutes):
   • Divide the class into small groups.
   • Provide each group with a chart paper and markers.
   • Ask them to create a comparison chart showing the differences between two types of secondary storage devices. Encourage creativity and use of visual elements.

Activity (10 minutes):

1. Group Discussion:
   • Review the answers to the worksheet as a class.
   • Facilitate a brief discussion on any misconceptions or interesting points that emerged during the activity.

Recap the key points covered during the lesson: types of secondary storage devices and their importance.

1. Highlight the real-world applications of secondary storage devices, connecting the lesson to everyday experiences.
2. Encourage students to explore more about these devices at home and share their findings in the next class.

Homework:

Ask students to write a short paragraph about a secondary storage device they find interesting, explaining why they think it's useful.

What is secondary memory? Give an example.
