Month 1: Understanding Networking Fundamentals

Learning objective

Learning Objectives

At the end of the lesson you will understand what a network is and the different types, including the distinctions between LAN and WAN. At the end of the lesson you will be able to explain the OSI model, detailing the seven layers and their respective functions. At the end of the lesson you will be able to compare the four layers of the TCP/IP model with the OSI model. At the end of the lesson you will be able to use Packet Tracer to design a simple network between two devices and observe data transmission across layers.

What do you already know about networks?

Introduction to Networks

Definition of a network. Importance of networks in communication. Overview of resource sharing.

Types of Networks

LAN: Local Area Network—covers small geographic areas. WAN: Wide Area Network—covers broad areas. Examples of each type.

Understanding the OSI Model

What is the OSI model? Explanation of the seven layers: 1. Physical 2. Data Link 3. Network 4. Transport 5. Session 6. Presentation 7. Application

Comparing OSI and TCP/IP Models

Overview of the TCP/IP model. Four layers of TCP/IP: 1. Link 2. Internet 3. Transport 4. Application Comparison with OSI layers.

Practical Application with Packet Tracer

Introduction to Packet Tracer tool. Designing a basic network between two devices. Observing data transmission across different layers.

Conclusion

Summary of key concepts learned. Importance of understanding networking fundamentals.

Definition List

Network: A collection of computers and devices connected together to share resources. LAN: Local Area Network, a network that covers a small geographic area. WAN: Wide Area Network, a network that covers a broad area. OSI Model: A conceptual framework used to understand network interactions in seven layers. TCP/IP Model: A four-layered model used for network communications, often compared with the OSI model. Packet Tracer: A simulation tool used for designing and understanding network configurations and data flow.
