Common Network Devices for CompTIA Tech+ (FC0-U71): Routers, Switches, Access Points, and Firewalls Explained
Every network, from a two-computer home office to a sprawling enterprise campus, is built from the same handful of hardware building blocks. CompTIA Tech+ (FC0-U71) Domain 2.0, Infrastructure, expects candidates to recognize these devices by name, know what layer of the network they operate at, and understand why you'd choose one over another. This is foundational vocabulary that carries straight through to A+ and Network+ , so getting it right now pays off on every exam that follows. This guide walks through the core network devices Tech+ wants you to know: hubs, switches, routers, wireless access points, modems, and firewalls, plus the all-in-one SOHO devices that combine several of these roles into a single box. We'll also connect each device to the common computing devices they support and the troubleshooting mindset you'll need when one of them fails.
