Overview of Networking Fundamentals by Russ White
This course delivers a clear and structured introduction to networking by exploring how communication works between systems, from physical connectivity to application-level protocols.
Using the simple model of two hosts and a router, Russ White explains core networking principles in a way that builds real understanding, not just exam preparation.
What You Will Learn
1. Core Data Flow and Network Structure
Begin with a foundational scenario: two hosts connected through a router
Learn how IP addressing and packet formatting are structured to enable communication
Understand the role of the router in forwarding and decision-making
2. Tunneling Theory and Transport Protocols
Explore different tunnel types and the theory behind encapsulation
Understand the purpose and behavior of TCP (reliable transport) and UDP (connectionless communication)
Analyze the importance of network models (like OSI) to organize layers, roles, and protocol interactions
3. Application-Level Protocols and Communication Methods
Examine how real-world applications use the network via protocols like:
FTP (traditional file transfer)
gRPC (modern remote procedure call mechanism)
RDMA (Remote Direct Memory Access for low-latency communication)
Understand the basics of socket-based communication and how applications interact with the network stack through the operating system
Why This Course?
This course is ideal for anyone who wants to understand how networks really work, starting from the simplest possible scenario and building toward modern application behavior.
Russ White focuses on the why, not just the how, helping learners form a strong mental model of networking concepts, one that prepares them for real-world troubleshooting, design, and advanced learning.
