A hub is a multi-port repeater, which means any signal from any connection is repeated to all other ports on the hub. This leads to more collisions as a result.
A switch is a multi-port bridge, and contains packet switching so that the message is only switched out the port of the destination device, not across all ports. Thus, the collisions are very small.
Switches and hubs can be used interchangeably in a network, with performance differences. The network does not know the difference.
what are the similarities between network switch and a hub
a hub is a central point in a network through which all the wires pass, a switch connects more than 2 LAN networks
The difference is in the way how they process communications between two or more computers. If you send some information to one computer only using hub it will resend the information to all computers in the network. When switches resend information to the only one computer.
Hi all,The main differance between the a switch and Hub is the hub will disribute the data among the system.(For eg: a hub have 8 port and in each system is connected and if a a system send a data of 100 mbps then all the system will share the data among themself and by the end system 100/8 it will send or get around 12.5mbps.) but incase of switch is won't do such things instead it will send the data as the same amount as it sends from the source.
Yes. The switch is acting as a "hub" between the various clients on the network.
You would have to be a little more specific.
A freewheel hub dose not make the pedals go forward when the backwheel is turning, a track hub dose.
no difference whatsoever
A crossover cable is used to connect a Hub or Switch to another Hub or Switch - or a PC to another PC.

switches does not have the database...much smarter than a hub.
Port in hub/switch refers to the interface where you connect your computers.
