Hubs are very similar to repeaters. A Hub is essentially a multiport repeater. Any electrical signal that comes into one port, goes out all other ports. Again, a very dumb device.
A repeater and a hub both work on the Physical Layer of the OSI Model.

A switch works at the Data-Link layer of the OSI Model, Layer 2.
To Troubleshoot Cisco and Windows networks, you need to know command equivalents. Cisco and Windows commands are similar but not identical.
Here are 7 Windows and Cisco commands that you should know:
- ping- used both in Windows and in the Cisco IOS to verify connectivity from of to a router (default gateway) and from a router to a PC.
- traceroute or trace in the Cisco IOS or tracert in Windows - used to trace the path your network traffic takes to a destination (like the web server you are trying to access) or from your router to a downstream router.
