Hub Networking

Hub networking is a network topology concept where all devices are connected to a central hub, which broadcasts data to every connected device. It operates at the physical layer (Layer 1) of the OSI model, using a simple, shared medium for communication. This approach is largely obsolete in modern networks due to inefficiencies like collisions and security vulnerabilities.

Also known as: Hub, Network Hub, Ethernet Hub, Repeater Hub, Multiport Repeater

Why learn Hub Networking?

Developers should learn hub networking to understand foundational network concepts, troubleshoot legacy systems, or study network evolution in computer science courses. It's relevant for historical context in networking protocols and helps grasp why switched networks (using switches) replaced hubs for better performance and security in local area networks (LANs).
