Hub
Hub is a transparent device. If you have several computers and which you want to connect you can use a hub. There are many versions of hub. They may be 4 ports as well as much more ports then 4. Basically hub has some inherent problems. First of all, if you connect 10 computers with hub then if a packet comes from internet to your hub it will just re-generate the bits of the packet and send it to all (10 computers). So it has large traffic domain. Hub does not contains any mechanism of forwarding or hub table on it.
Switch
Switch is a device which can solve much of the problems of the hub. It has different traffic domain. The most important issue regarding switch that it makes a dedicated path between switch and the connecting computer. And at the same time you can use different bandwidth wires (standard ethernet, fast ethernet, gigabyte ethernet) with switch.
