---
#### Objectives:
By the end of the lesson, students will be able to:
1. Understand the basic concepts of Disk Operating System (DOS) and Windows Operating System.
2. Identify and explain the key differences between DOS and Windows OS.
3. Demonstrate an example of how each operating system works.
---
#### Materials Needed:
- Projector (for presentation)
- Computer with both DOS and Windows or simulation software
- Whiteboard and markers
- Handouts with comparison table
---
#### Lesson Outline:
**Introduction (10 minutes)**
- Greet the students and briefly discuss today's objectives.
- Quick warm-up question to engage students: "How many of you have used Windows before? Has anyone heard of DOS?"
---
**Presentation (20 minutes)**
- **Overview of Disk Operating System (DOS)**
- Introduce DOS as one of the first widely used operating systems for personal computers.
- Explain how DOS uses a command-line interface (CLI) and its reliance on text-based commands.
- Demonstrate basic DOS commands and their effects using a computer or simulator:
- `DIR` (lists files and directories)
- `COPY` (copies files)
- `DEL` (deletes files)
- **Overview of Windows Operating System**
- Introduce Windows as a popular graphical user interface (GUI) based operating system developed by Microsoft.
- Show various versions and explain the evolution from earlier versions like Windows 95 to the latest (e.g., Windows 10/11).
- Demonstrate basic operations in Windows:
- Navigation through the Start Menu
- File and folder management through File Explorer
- Installing and using applications
---
**Comparison of DOS and Windows (15 minutes)**
- Present a comparison table featuring key differences:
- **User Interface:** DOS (CLI) vs. Windows (GUI)
- **Ease of Use:** DOS (requires memorization of commands) vs. Windows (user-friendly icons and menus)
- **Multitasking:** DOS (single task at a time) vs. Windows (multi-tasking capabilities)
- **Memory Management:** Briefly touch on simpler memory management in DOS vs. more complex and efficient memory management in Windows.
- Discuss the practical implications of these differences for users.
---
**Activity (10 minutes)**
- Hands-on exercise:
- Divide the class into small groups and assign each group either a DOS or Windows simulation task.
- DOS Task: List all files, copy one file to a new directory, delete the file.
- Windows Task: Create a new folder, move a file into that folder, open an application.
- Allow students to share their experiences and any challenges faced.
---
**Conclusion (5 minutes)**
- Recap the main points discussed during the lesson.
- Ask students to summarize the key differences between DOS and Windows Operating Systems.
- Provide a short quiz on the differences discussed to reinforce learning.
---
**Assignment:**
- Ask students to write a short essay (200-300 words) on "The Evolution of Operating Systems from DOS to Windows" and highlight the major milestones.
### Additional Notes:
- Provide additional resources such as online tutorials or videos for students who want to explore the topic further.
- Encourage students to practice DOS commands and basic Windows operations at home if possible.
