  • A computer network is the infrastructure that allows two or more computers (called hosts) to communicate with each other. The network achieves this by providing a set of rules for communication, called protocols, which should be observed by all participating hosts. The need for a protocol should be obvious: it allows different computers from different vendors and with different operating characteristics to ‘speak the same language’. This chapter introduces the fundamental concepts of computer networks.

  • DNS architecture is a hierarchical distributed database and an associated set of protocols that define: •A mechanism for querying and updating the database. •A mechanism for replicating the information in the database among servers. •A schema of the database. DNS originated in the early days of the Internet when the Internet was a small network established by the United States Department of Defense for research purposes. The host names of the computers in this network were managed through the use of a single HOSTS file located on a centrally administered server....
