Routing traffic and routing costs

Question 1

What happens during routing?

Answer 1

Understand that during routing, networks will
search for the shortest path and the fastest
nodes to transfer data. Together the path
between nodes and the speed of the nodes
are assessed by the device transmitting data.

Question 2

How do computers calculate routing costs?

Answer 2

Computers will look for the route with the
lowest cost (that is the shortest path and
fastest nodes) and transmit data via this lowest cost route
