I am not trying to turn this into a networking class, but the information I get here is priceless, and I do want to use LINUX in networking!

 

I know that routers are used to transfer traffic from two different networks that use different protocols. i.e. a LAN that used netbeui connects to a router that connects it to the internet (TCP/IP)

 

Does that mean that on each of the computers in the network, TCP/IP would not be installed? For some reason that does not sound logical for me, so what would be an example of traffic that is not tcp/ip that the router would route to the outside network(internet?)

 

Lets say that all the computers in the network are Linux boxes J, and we used tcp/ip as the protocol. Then we wanted to give interenet access to the computers in this LAN. So we got a router (does it have to be a router?). how would the router know if the traffic should be routed to the outside or if it should stay within the computers of the LAN? Is it because of the use of a mask or is it the use of LAN ip address that are different than what is available on the internet?

 

 

My last question is what is the use of switches and why would salespeople try to sell that to you instead of a hub for a home network?

 

Thank you !
