A hub is a device that connects a network of computers together, usually in a server to client network. It's a connectivity device, which allows information to be transferred between and to and from the server and computers. If you have two computers you don't need a hub, only a network cable and get the computers to see each other. A hub works on a small LAN or part of a larger LAN or WAN.
A switch is also a connectivity device, although what I remember it is, is that it's used in major networks or in medium sized networks - it's a waste of asset budget in a small network due to the small amount of numbers present on the network. The switch, like the hub connects the computers together, etc, etc, although it can do this on a much larger scale. You get a 10 or 12 point switch as your smallest (don't think they make 6 - too expensive - ppl will just use hubs), and they are also used where lots of data transfer is happening.
Switches basically take the data, and relay it to the next switch. So where your network message(s) get weak, you would put a switch in to make it strong again.

Hubs are dumb devices which just forward signals from a sending computer to all the other computers on the network. This can lead to collisions in network traffic. The higher the number of collisions, the slower the network performance.
Switches are smarted hubs which, though their internal logic, avoid collisions by sending the traffic only on the port where the destination computer is known to be found (they use caches for this) instead of flooding the entire network.

if i recall.... a hub sends a signal to all pcs on the network and a switch sends the signal to the pc concerned so therefore switches are much faster at transferring data on a network......i think!!!

A switch switches between connections separately and hub will use several connections at the same time and separate them
