MicroNuggets: Broadcast Domains Explained

Start learning cybersecurity with CBT Nuggets. https://courses.cbt.gg/security In this video, Keith Barker covers BroadCast Domains: what they are at layer 2, how they interoperate with switches and hubs, and the common code name that’s used to refer to it on networks today. A cornerstone of this video is understanding the difference in how switches and hubs operate and how BroadCast Domains work with each piece of equipment. Keith discusses BroadCast Domains and how it’s known by several different names. He’ll cover what a BroadCast Domain is at level two, how it interoperates with a switch or a hub, and then he’ll talk about the code name by which it’s commonly referred to on networks today. A switch memorizes layer two hardware addresses on each device; these are burned in from the factory, and the switch can take that information and make four ring decisions based on those layer two addresses. This is a smart approach to managing traffic, which is different from the “dumb” approach a hub uses. A switch can differentiate where traffic needs to go and only send those bits to the desired location, where a hub will send that information to every other port. A BroadCast Domain helps manage this. 🌐 Download the Free Ultimate Networking Cert Guide: https://blog.cbt.gg/gliv ⬇️ 13-Week Study Plan: CCNA (200-301): https://blog.cbt.gg/fc8a Start learning with CBT Nuggets: • Building a Business Switched Network | https://courses.cbt.gg/ho3 • Intro to Networking | https://courses.cbt.gg/tuv • CompTIA Network+ (N10-007) | https://courses.cbt.gg/lvb
