What does a network bridge actually do — and why is it mostly outdated? CBT Nuggets trainer James Conrad breaks down how a bridge works at Layer 2 of the OSI model, how it manages MAC addresses, and how it splits up collision domains to reduce network traffic. You’ll learn the difference between using a hub, a bridge, and a switch, and why modern networks rely on switches instead of older technologies.
