The Internet is the most renowned computer network that allows billions of people to connect and share resources at the same time. The network employs a packet switching model to route data traffic through an almost limitless number of connections and pathways. Each packet contains control information as well as user information. The control information contains the destination and source network addresses, error detection codes and sequencing information.
