Subject : Operating System

Period: Third

Topic: Memory Management

Teaching Item: Types of Paging: Fixed-Size & Variable-Size

Class: BICT 4th Semester

Unit: Three

Time: 50 min

No. of Students: 20

1. Specific Objective:

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

• Define Fixed & Variable Size Paging.
• Differentiate between Fixed-Size and Variable-Size paging.

2. Instructional materials:

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

3. Teaching Learning Activities:

• I will enter the classroom and will motivate students by sharing the importance of understanding memory management in operating systems once again then I will write today's topic on board so that the students will have knowledge on what we are going to learn today.
• Begin the class by asking some questions to students related to paging and memory management to check their understanding of previous lessons.
• Open the presentation slide and briefly introduce topic.
• Further I will explain these two types of paging along with their definition, advantages, limitations and some using scenarios examples. While explaining each of them I will also make comparison between these two.
• I will summarize the lesson in brief, highlighting the key differences between Fixed-Size and Variable-Size paging.

4. Assessment:

During the session, ask questions like,

• Can anyone explain what paging is?
• What is the main difference between Fixed-Size and Variable-Size paging?

5. Evaluation:

1. How does Variable-Size paging handle memory allocation differently from Fixed-Size paging?

Point added for a correct answer:
Points for an incorrect answer:
Ignore the questions' coefficients:

1 Which of the following statements best describes Fixed-Size Paging?

	Memory is divided into variable-sized pages based on process requirements.
	Memory is divided into fixed-sized pages regardless of process requirements.
	Memory allocation size changes dynamically during execution.
	Memory is managed without using paging techniques.

2 What is a key advantage of Variable-Size Paging compared to Fixed-Size Paging?

	Fixed-size allocation leads to efficient memory utilization.
	It requires less overhead in terms of memory management.
	It allows for more efficient use of memory by allocating space based on process needs.
	It simplifies the memory management process by using a uniform page size.
