What is the main problem with using a hub in a shared CSMA/CD Ethernet network?

Hubs create a single collision domain, meaning that all devices connected to the hub share the same network bandwidth Signup and view all the answers

How do bridges help to address the problem of shared CSMA/CD communication?

Bridges learn MAC addresses and effectively split the network into two collision domains, reducing the likelihood of collisions Signup and view all the answers
