Answer : Problem: Role of Router
|
|
A routers only job in a network originally was to split broadcast domains in manageable routable subnets. Before routers everything was bridged and large networks were riddled with latency and packet errors and extreme drop rates.
The problem was solved by routers and subnetting address ranges it to routabe groups of network nodes.
