Specific Objectives

At end of the class

• Students will gain an understanding of secondary memory in computers, including its types, functions, and significance in data storage.
• Differentiate between primary memory and secondary memory.

Materials Needed:

1. Whiteboard and markers.
2. Examples of secondary memory devices .
3. Handouts summarizing key points

Introduction :

• Begin with a brief review of primary memory (RAM) and its temporary nature.
• Introduce the concept of secondary memory as a form of non-volatile, long-term storage.
• Discuss the importance of secondary memory in retaining data even when the computer is powered off.

Main Content :

1. Types of Secondary Memory (10 minutes):
   • Present different types of secondary memory, including hard disk drives (HDD), solid-state drives (SSD), Pen drives, memory cards, and optical disk (CDs, DVDs).
   • Discuss the characteristics and advantages/disadvantages of each type.
2. Functions of Secondary Memory (10 minutes):
   • Explain the primary functions of secondary memory, such as storing data, applications, and the operating system.
   • Discuss how it facilitates data transfer between devices and the significance of long-term storage.
3. Storage Capacity and Performance (5 minutes):
   • Discuss how storage capacity varies among different secondary memory devices.

Activity :

• Break the class into small groups and ask them about different between secondary memory and primary memory.
• Ask them to discuss and present the advantages and disadvantages of their assigned device.

Homework:

• Assign a research project on emerging trends in secondary memory technologies.
• Ask students to compare the storage capacity and performance of different secondary memory devices.

Assessment:

• Evaluate understanding through class participation, group presentations, and responses to questions.
