Let me start with this simple one - It is something to do with Networking. Do you know how a wired and a wireless network is physically established?
Ans - All the computers that are suppose to be present in the wired Network are connected by means of wires to a common router or a hub which is configured at the server Computer. The workstations can have any windows installed on it and the Server computer should have the Windows NT Server installed on it. All the wireless networks are established by means of a wireless PC cards that is to be installed on each computer participating in the wireless network.
You can connect two computers/laptops directly, without the use of an intermediate router, by means of wire, too, and see one computer in the other. However, it is best to use a router when connecting a small number of computers in a domain.
A switch, another networking device, can also be used in the place of a router or a hub.
A mix and match is also possible where some computers are physically connected by means of wire and others are wirelessly connected to the network. A special case is when we use Desktops and Laptops. The Desktops are connected to the hub/router by the wires and the Laptops are wirelessly connected in the network by means of wireless PC cards.
Sometimes, when you don't see one computer from the other computer connected via a router, refreshing the router physically by means of a button on it solves the problem but note that refreshing the router will throw away all your ip-address and subnet mask address that you have got from your ISP, if you have taken internet connection for your network. So, select to refresh the router depending on the type of situation.
Hope, this was helpful to amateurs.
