Episode 14: Common Networking Hardware — Switches, Routers, and Beyond
This episode introduces the major hardware components that make up a network, focusing on their core functions and where they fit into the topology. You’ll learn what switches, routers, access points, modems, and firewalls actually do, and how they work together to move traffic securely and efficiently. Each device is explained in terms of its OSI layer and use case.
We also discuss how these devices are used in different environments, such as SOHO, enterprise, and data center networks. Understanding the role and behavior of network hardware is foundational knowledge that will be applied throughout your studies and your IT career.
