In this CompTIA Network+ training video, we’ll go over two network devices, bridges and switches, which are used to create and control collision domains.
As you’ll learn in the video above, bridges operate at the Data Link layer of the OSI (Open Systems Interconnection) model. They have simplistic routing tables (compared to routers) based on MAC addresses and are used to create separate collision domains.
Switches work very similarly to bridges, except they feature multiple ports. They can be used so that each computer on the switch resides in its own collision domain.

Hello Sir,
This blog is useful for beginners. And the immediate response for any query we send is amazing!
Can you please explain the internal process of communication between a router and a switch? How a packet and a frame communicates?
Thanks.
