Routing And Switching Questions
A hub is a networking device that operates at the physical layer of the OSI model and simply broadcasts incoming data to all connected devices. It does not have the ability to filter or manage network traffic. On the other hand, a switch operates at the data link layer of the OSI model and intelligently forwards data packets only to the intended recipient device based on its MAC address. It can effectively manage network traffic, improve network performance, and provide better security compared to a hub.
