Core Networking Devices Explained: Hubs, Switches, Routers, and More

Описание: *Ever wonder how your devices actually connect, communicate, and stay secure on a network?* In this video, we break down the *essential networking devices* that form the backbone of modern IT and cybersecurity infrastructures, from the humble *hub* to advanced tools like **firewalls**, **load balancers**, and **intrusion prevention systems (IPS)**.

Whether you’re new to networking, prepping for a certification, or brushing up on the OSI model, this video will give you a clear understanding of how each device works, where it fits in the stack, and how it contributes to a secure and efficient network.

👉 *What You’ll Learn:*

The difference between hubs, switches, and routers
How access points bring wireless devices onto the network
The role of firewalls, modems, and SOHO devices
Why load balancers improve performance and reliability
How IDS and IPS detect and prevent cyber threats
Where each device fits on the *OSI model* (Layers 1–7)
Real-world use cases and security considerations

From *LAN setup* to *cyber defense architecture**, understanding these devices is critical to mastering both **networking fundamentals* and **modern cybersecurity**.

If you’re studying for certifications like **CompTIA Network+**, **Security+**, or **CCNA**, this is a must-watch.
