kaj je to router?

Router - A device which moves network data from one segment of a network to another. Routers are also responsible for determining where data needs to go in order to reach its destination. Routers can "learn" these paths and more easily send data to its destination. (http://www.hub-tech.net/terms.html).

To move info throughout the system we need to identify the individual computers, so each computer has a name (Computer name), and each LAN has name (Workgroup name).

To move the info we also need Software Protocols. A big number of protocols are available, some of them are just an outcome of "Manufactures Pride", i.e. each big player (Novel, Microsoft, IBM, etc.) develops its own protocol. Some has functional differences. Members of this board will find themselves mainly using three protocols.
