#Dummy hub
Data transmission to other computers.
It's just relaying network between them.
Hub uses entire network bandwidth.
So It means if you add more devices, they divide the capacity in limited resource.
Conclusion : Network speed might be degraded when it exceeds threshold. That was called by "Network Traffic".
(P.s. When you want to construct computer net, Make nodes below 10.)
#Router
Even structure is different each other, this can communicate with another network.
It can be in local area, metropolitan area, and wide area network.
Device survey and select the best data arrival route which based on IP address.
It is called the "routing function".
Routing is decided by routing table which in router. Futhermore, routing table sends data to that route which router searching next address based on destination's address in internet.
Considering destination will be
#function of another things
- Error packet disposing, confusion control function.
- Designate network traffic direction belong logic address.
- Use for connecting more than two networks.
- playing desicive role to send web page request at destination.
