2) Replaced by a Switch, The HUB is launched - What transmission rate would be available now? - 100 Mbps the maximum is available to each node

3) Whats the difference between the way a hub and router send data around a network? - finds the best/fastest/quickest/most efficient route to send data, HUB amplifies the signal and broadcasts it to all nodes

4)Why do Routers need processing capability? - to process choose and calculate the path

5) Why are NIC's needed? - Network Interface Card - so we can connected, hardware and software required to allow communication between two networks, changing data so it can be understood etc ...
