What is the difference between a switch and a hub?

Options
- Switches operate at physical layer while hubs operate at data link layer
- Switches operate at data link layer while hubs operate at transport layer
- Switches operate at data link layer while hubs operate at physical layer
- Switches operate at transport layer while hubs operate at physical layer

Explanation-

-Hub operate on physical layer. Hubs are classified as Layer 1 devices per the OSI model.
-Switch operate on data link layer. Network switches operate at Layer 2 of the OSI model.

Further information

In my last I said Transport. I meant to say Network layer

Router = Network layer. Do not get confused!

Application
Presentation
Session
Transport
Network = Router
Data = Switch
Physical = Hub

See how they go up in order?

Further information

Router = Transport
Switch - Data Link
Hub = Physical


Think of it this way.

The Hub is the stupidest of the devices. It only takes and throws information out to anything.. So it goes to the bottom layer.
The Switch is kind of smart. It does some switching so we stick it one layer up at the Data link layer.
The Router is very smart and can be programmed to do MANY things.. So it goes up yet another layer to the Transport layer.


Thinking like this will make it easier to remember and understand :)

Switch and Hub

swith - Data link layer
Hub - Physical later
