about hubs, Bridge, Gateway, switches and routers
Gateway: It connects networks of difrnt kinds.eg connecting a network of PCs to a mainframe computer.
Bridge: It connects networks of the same type but in different topologies.like ur skool computers different computer labs (LAN networks) are connected together maybe 1 is a star and da other is a ring topology
Router: It connects several networks. It is smart enough 2 pick da right path of communications traffic, If there is a partial failure of the network, a router looks for an alternate route.
Hubs: Connect the stations in the LAN working by broadcasting ie radio signals
Switch: It is like a hub but its more intelligent 2 no the IP addresses.
I hope that this helped.. :)
