The Internet is the most famous computer network with billions of users to connect and share the same resources simultaneously. The network Bonuses uses a packet switching model to guide data traffic through an infinite number of possible pathways and connections. Each packet includes control information as well as data from the user. The control information contains the destination and source network address and error detection codes and sequencing information. The payload is contained in the data part of a byte.
