- Collision Domains and Broadcast Domains = Apples and Oranges
- May 5, 2015
- Sean Wilkins, co-author of CCNA Routing and Switching 200-120 Network Simulator, doesn't approve of blurring collision domains and broadcast domains. Though these models are often taught together, modern technology has outpaced some of the ideas, and networking specialists who are new to the field need to distinguish between current terminology and outdated concepts.
