Question 1

What are the major differences between a hub and a switch?

Accepted Answer

The major difference is that switches are intelligent. They examine each frame that they receive for the destination MAC address and then send the frame out the correct port for that address. A hub simply accepts a frame from one of its ports and then sends it out all ports. A switch also keeps a table of MAC addresses so that it knows where to send a frame. Because a switch can control where it sends a frame, devices that are connected to a switch can communicate at the same time, allowing each device to access the full network bandwidth. With a hub, only one device can transmit at a time so the bandwidth is shared among all connected devices. Also, because a switch controls the flow of frames, there is little chance of a collision. In a hub, collisions might occur frequently when under heavy use.
