Complete Computer Networking & Network Security for Beginners

If you are starting from zero and want to understand computer networking and network security properly, this video is made for you.

This is a complete beginner-friendly foundation video that explains how computer networks actually work and how security fits into networking in the real world. You don’t need any prior IT background, coding knowledge, or cybersecurity experience to follow this session.

In this video, we start from the absolute basics — what a computer network is and why it exists — and slowly build your understanding step by step. You will learn about network topologies, network devices, protocols, the OSI model, and how all of this connects to information security, cybersecurity, and cryptography.

Instead of memorising definitions, the focus is on conceptual clarity. This is the kind of understanding you need if you are preparing for:

Cybersecurity careers
SOC or network security roles
CompTIA Network+ / Security+
CISSP or GRC foundations
Engineering or IT fundamentals

We also explain how networking knowledge becomes the backbone of cyber security — how data flows, where attacks happen, and where security controls are applied. You will clearly understand the difference between networking, information security, cyber security, and cryptography, without confusion.

This video is intentionally designed to stay relevant for years. Networking fundamentals do not change every year — protocols, models, and concepts remain the same — which makes this an evergreen learning resource you can return to anytime.
