Introduction
Network routing is the process of selecting a path across
one or more networks. The principles of routing can
apply to any type of network, from telephone networks to
public transportation. In packet-switching networks, such
as the Internet, routing selects the paths for Internet
Protocol (IP) packets to travel from their origin to their
destination. These Internet routing decisions are made
by specialized pieces of network hardware
called routers.

Network Topology
Network topology is the arrangement of the
various elements (links, nodes, etc.) of a
computer network. It can be used to define or
describe the arrangement of various types of
telecommunication networks, including
command and control radio networks, industrial
fieldbuses and computer networks. Network
topology can be used to define physical or
logical topologies.
