Subject : Operating System

Period: Third

Topic: Memory Management

Teaching Item: Introduction to Memory Management

Class: BICT 4th Semester

Unit: Two

Time: 50 min

No. of Students: 20

1. Specific Objective:

At the end of this lesson, students will be able:

• Define memory management and its importance in an operating system.
• Identify various memory management strategies: Single Contiguous Allocation, Partitioned Allocation, Paged Memory Management, and Segmented Memory Management.

2. Instructional materials:

• Daily Usage Materials,
• PowerPoint Presentation Slide,
• Laptop,
• Projector etc.

3. Teaching Learning Activities:

• I will enter the classroom and greet the students and will motivate them before starting the lesson for their concentration on the lesson, and then I will write today's topic on the board.
• Why is memory management important in an operating system? Begin the class by asking questions to gauge prior knowledge: Can anyone explain what memory management is?
• Open the presentation slide and briefly introduce the concept of memory management and its significance in operating systems. Explain the importance of memory management in detail in multi-processing environment.
• Introduce each of the memory management strategies like: Single Contiguous Allocation: Memory is allocated to a process in a single contiguous block., Partitioned Allocation: Memory is divided into fixed-size partitions and processes are allocated memory from these partitions., Paged Memory Management: Memory is divided into fixed-size blocks called pages. Processes are divided into blocks called pages as well., and Segmented Memory Management: Memory is divided into variable-size segments. Each segment represents a logical division of a program.
• Summarize the key points covered in the lesson. And encourage students to ask questions and clarify doubts.

4. Assessment:

During the session, ask questions like,

• Which memory management strategy allocates memory to a process in a single block?
• In which memory management strategy is memory divided into fixed-size partitions?
• What are the main differences between paged and segmented memory management?

5. Evaluation:

Explain about memory management along its importance and its various strategies.
