Routers, Switches, Bridges, and Hubs

How does a Bridge/Repeater handle collision domains and broadcast domains.

Bridges break up collision domains but do not break up Broadcast domains.

What Layer of the OSI model does a Bridge/Repeater operate?

Bridges are layer two devices

What is the maximum speed and duplex of a hub?

Hubs operate at 1/2 duplex and at a maximum of 100MB/sec.

What Layer of the OSI model does a Hub operate?

It operates at layer 1 of the OSI model.

What is the difference between a layer 2 switch and a layer 3 switch

Layer 3 switches have all the benefits of a switch and router combined into one device. The switch can perform layer 3 routing at near wire speeds

How does a Router handle collision domains and broadcast domains.

Routers break up collision domains and broadcast domains.

What is the maximum speed and duplex of a switch?

Switches are mostly full duplex and can range between 10/10/1000 and even 10000/Mbs!

How does a Switch handle collision domains

Switches break up collision domains.

Tell me the difference between Hubs and Switches when it comes to Loop back.

hubs don't have any provisions to stop loops and switches have loop prevention
