Theory Distance Vector routing DVR algorithm is unlike Dijkstra's algorithm which is a non-adaptive routing algorithm and means that it is purely static, that is pre-destined and fixed, not flexible in networks where congestions are more prone to occur.

DVR is an adaptive routing algorithm in which the information from neighbours is maitained well by each and every node and this helps us to determine the simplest path possible in a changing network. Though, one of the node may fail, still, the destined node is reachable through other possible intermediate nodes that are found out by the DVR algorithm. The perfectly executing program below shows it live below.

Obtain broadcast tree for it. Theory IP addressing is the allocation of unique ID to each and every system connected in a network to maintan communication among them through out the affixed network.

There are 5 classes of IP Addresses namely A through E with the range varying from one class to the other class. A subnet is a network allocation to similar systems or same hierarchial systems present in a allocated network like an organisation. Each and every system can be reachd through a client-server computing environment where the server acts as the Master and the clients acts as the Slaves to form a Master-Slave computing environment.

Below programs show the calculation of network addresses with subnet predefinition and subnet generation. Not only from the examination point of view, I have used the above concepts in my academic as well as professional projects which also include concepts regarding Operating Systems , Compiler Design , Web Technologies and UML diagrams. A combination of all these concepts in terms of programs as depicted above would really mean a lot for every Computer Science backgroun student.
