Network switches are used to connect two different segments of a LAN. If a LAN has to many nodes (objects on the LAN) that are communicating, the chances of a collision occurring are higher. To lower this chance and to increase bandwidth add nodes that communicate with one another often (such as two computers and a printer) then connect the output to the LAN (everything else). This will keep bandwidth lower and will lower collisions.
However a switch isn't allways the way to go. If you have a smaller network (say a max of 10 computers or so) you might want to use a router instead. Routers help direct trafic. So two nodes can talk while others on the same LAN are too!

also, maybe try searching before posting such a silly question.
A network switch is used to connect various network devices. Switches have the ability to receive a message and relay it to just one device which the message was intended whereas a router sends it to every device on the network.
Via Ethernet cables, in the most typical case.
You can use either a network hub or a network switch to set up your network
Ethernet
Although some would suggest that a switch could segment a network (and it does use the MAC address for switching) more properly a bridge would be the answer if you are speaking of segmenting a network.

If you printer has a printer server attached or network compatible, the answer is yes you can.
Analog switches Fiber optic cables
It does not have a mechanical switch. Try to use Fn+F8 to activate wireless adapter.
Yes, switch as well as hub and router are network devices.
it is a switch in hubs
durability
interconnecting several networks using different technologies.
A managed switch is a network switch, which is used for connecting computers and network devices. It is handy because it allows you to handle individual ports of the switch.
