OSI Model Explained | 9th Class Computer Chapter 6 | 7 Layers of OSI in Computer Network

OSI Model Explained | 9th Class Computer Chapter 6 | 7 Layers of OSI in Computer Network Welcome to Easy Computers with Abdullah! 🎓 In this detailed lecture of 9th Class Computer Chapter 6 – Computer Networks, we’ll explore one of the most important topics — the OSI Model (Open Systems Interconnection Model) — explained in a simple, visual, and example-based way that every student can easily understand. The OSI Model is the foundation of computer networking — it describes how data travels from one device to another through 7 well-defined layers. Whether you’re a 9th class student, a beginner in computer networking, or someone who wants to understand how the internet really works, this video is perfect for you! 🚀 What You Will Learn in This Lecture ✅ Complete Explanation of OSI Model – What it is and why it’s important in networking. ✅ 7 Layers of OSI Model with Real-Life Examples: Layer 1: Physical Layer – Deals with cables, signals, and hardware. Example: Ethernet cables, hubs. Layer 2: Data Link Layer – Ensures reliable data transfer between devices. Example: Switches, MAC addresses. Layer 3: Network Layer – Handles IP addressing and routing. Example: Routers, IP packets. Layer 4: Transport Layer – Manages reliable data delivery using TCP and UDP. Example: Error checking, flow control. Layer 5: Session Layer – Manages communication sessions between systems. Example: Logging into a website. Layer 6: Presentation Layer – Converts data formats for understanding. Example: Encryption, compression. Layer 7: Application Layer – Interfaces with user applications. Example: Browsers, email, and chat apps. ✅ Real-Life Analogy: You’ll also understand the OSI 7 Layers using a parcel delivery system example, making the entire concept easy to visualize and remember. ✅ Exam-Focused Content: Every point is explained according to the 9th Class Computer New Book 2025 (Punjab Textbook Board). These explanations help you write short and long questions perfectly for board exams. ✅ Who Should Watch: 🎯 9th Class Computer Science Students 🎯 Beginners in Networking 🎯 Students preparing for board exams or viva 🎯 Anyone curious about how data communication and internet connections work ✅ Video Features: 📘 100% syllabus-based 📘 Simple language and easy examples 📘 Clear explanation of each layer 📘 Real-life relatable learning 📘 Ideal for board preparation & revision 📅 Time Stamps 00:00 | Channel Intro – Easy Computers with Abdullah 00:10 | Introduction to OSI Model with Hook 00:49 | Layer 1 – Physical Layer Explained with Example 01:30 | Layer 2 – Data Link Layer Explained with Example 02:03 | Layer 3 – Network Layer Explained with Example 02:36 | Layer 4 – Transport Layer Explained with Example 03:10 | Layer 5 – Session Layer Explained with Example 03:43 | Layer 6 – Presentation Layer Explained with Example 04:17 | Layer 7 – Application Layer Explained with Example 04:55 | OSI 7 Layers Explained with Real-Life Parcel Delivery System Example 09:02 | Board Exam Important Questions Reminder 09:12 | Subscribe to Easy Computers with Abdullah 📢 HashTags #9thClassComputer #ComputerNetwork #OSImodel #OSI7Layers #Class9ComputerScience #NetworkingLecture #ComputerBasics #BoardExamPreparation #EasyComputersWithAbdullah #NetworkingForBeginners #ComputerNewBook2025 #PakistaniStudents #ITEducation #LearnNetworking #ComputerLecture
