CYBERSECURITY MASTERCLASS || SESSION 4 || COMPUTER NETWORKS

Understanding computer networks is crucial for anyone starting in Cybersecurity! In this video, we’ll take you through the fundamental concepts of computer networks – the bedrock of secure, efficient digital communication.

We'll start by explaining What a Computer Network Is, covering how networks allow devices to connect, share data, and function securely. Then, we'll explore the Types of Networks – from LANs and WANs to MANs and PANs – and why these different types matter in cybersecurity.

After that, we’ll look at Network Topology, showing you how different structures like star, ring, and mesh topologies impact network performance and security.

Finally, we’ll break down the essential OSI and TCP/IP Models – the frameworks that structure data flow across networks and influence secure communication. We’ll go through each layer in these models, connecting them to cybersecurity practices like encryption, firewalls, and data integrity.

Whether you’re just getting started in cybersecurity or looking to brush up on network basics, this video gives you the foundation to protect and secure networked systems. Hit play and get ready to build your cybersecurity skills from the ground up!
