2.5.3 Message Switching

Welcome to Unit 02 of our comprehensive series on networking fundamentals! In this unit, we're diving deep into the OSI (Open Systems Interconnection) Model, a cornerstone of modern networking. The OSI Model provides a structured framework for understanding how data moves across networks, from the physical transmission of bits to the high-level interactions between applications. Join us as we unravel the complexities of the OSI Model, explore transmission media, tackle transmission impairments, and compare various switching techniques.

2.1 Introduction of OSI Model:
Lay the foundation with an introduction to the OSI Model, its purpose, and its relevance in network communication.

2.2 OSI Model:
Explore each layer of the OSI Model, from the Physical Layer to the Application Layer, understanding their functions and interactions.

2.3 Transmission Media:
Discover the different types of transmission media, including guided media like twisted pair, coaxial, and optical fiber cables, as well as unguided media.

2.4 Transmission Impairment:
Understand the factors that can degrade signal quality during transmission and techniques to mitigate these impairments.

2.5 Switching:
Compare various switching techniques, including circuit switching, packet switching, and message switching, and their suitability for different network scenarios.

2.6 Comparison of Different Switching Techniques:
Delve deeper into the comparison of different switching techniques, analyzing their advantages, disadvantages, and real-world applications.
