Switches are the heart of all computer networks and are responsible for connecting up to 1000's of computers together.
If you want to know how does a network switch work then I hope this video explains that to you.
I will also explain the difference between a hub and a switch.

A network switch looks a lot like a network hub. Unlike hubs, however, network switches are capable of inspecting incoming messages as they are received and directing them to a specific port—this creates an arp table on the switch so it knows where each device is and where to send the traffic destined for that device.
A switch determines the source and destination addresses of each packet and forwards data only to the specific devices, while hubs send the data to every port except the one that received the traffic.
A switch is a lot more efficient on bandwidth as data only is sent to where it needs to go.
Switches are often confused with Routers, but a Router is a completely different device which decides which network to send traffic to.
The confusion has come from most home broadband routers now including a small 4 port switch so box boxes are combined and most people refer to it as the router.
